Carbon monoxide solubility in ionic liquids: determination, prediction and relevance to hydroformylation.

The solubility of carbon monoxide in 37 ionic liquids and in some organic solvents has been determined using high-pressure (13)C NMR spectroscopy; a method for predicting the CO solubility is demonstrated, and it was shown that the rate of the hydroformylation of 5-hexen-2-one does not correlate with the CO solubility, as expected from the determined relative solubility of CO compared to H(2).

Reactor Design Issues for Synthesis-Gas Fermentations.

Synthesis gas is readily obtained by gasifying coal, oil, biomass, or waste organics and represents an abundant, potentially inexpensive, feedstock for bioprocessing. The primary components of synthesis gas, carbon monoxide and hydrogen, can be converted into methane, organic acids, and alcohols via anaerobic fermentations. Bioconversion of synthesis gas is an attractive alternative to catalytic processing because the biological catalysts are highly specific and often more tolerant of sulfur contaminants than inorganic catalysts. However, because the aqueous solubilities of carbon monoxide and hydrogen are low, synthesis-gas fermentations are typically limited by the rate of gas-to-liquid mass transfer. Consequently, a major engineering challenge in commercial development of synthesis-gas fermentations is to provide sufficient gas mass transfer in an energy-efficient manner. This paper reviews recent progress in the development of synthesis-gas fermentations, with emphasis on efforts to increase the efficiency of gas mass transfer. Metabolic properties of several microbes able to ferment synthesis gas are described. Results of synthesis-gas fermentations conducted in various bioreactor configurations are summarized. Recent results showing enhancement of synthesis-gas fermentations using microbubble dispersions are presented, and studies of the mass-transfer and coalescence properties of microbubbles are described.

Solution process of CO gas in liquid phase methyl formate and methanol was experimentally studied under various pressures and temperatures to evaluate the transport effect of CO gas in the liquids in a two-step methanol synthesis process which starts with carbonylation of methanol to methyl formate, then followed by the hydrogenolysis of the formate. The solubility of carbon monoxide in liquid phase methyl formate and methanol were measured by the decrease in pressure due to absorption at pressures up to 1700 kPa and temperatures form 20 to 140°C. It was obtained that the solubilities were between 3.1×10-3 and 11.5×10-3 for CO in methyl formate, and between 4×10-4 and 10.7×10-3 for CO in methanol. The Henry's law constant was about 160 MPa at a temperature of 20°C for CO in methyl formate, and about 250 MPa at temperatures under 100°C and pressures under 1000 kPa for CO in methanol. The Henry's law constant decreased with the increase of temperature. Empirical correlations for solubility at various temperatures and pressures were given based on the experimental data.

Solubility and Diffusivity of Carbon Monoxide in Liquid Methanol

The solubility of carbon monoxide in liquid methanol was measured by the decrease in pressure due to absorption at pressures up to 1500 kPa and temperatures up to 140 °C. The mole fraction solubility was between 4.2 × 10-4 and 11 × 10-3, and the Henry's law constants were about 250 MPa at temperatures lower than 80 °C and pressures up to 1000 kPa. The diffusivity of CO gas in methanol was determined by measuring the diameter and solution time of a single CO bubble in methanol over the temperature range from 25 °C to 90 °C at a pressure of 500 kPa. The diffusion coefficients ranged between 5 × 10-9 m2·s-1 and 9.5 × 10-9 m2·s-1 for the temperature range from 25 °C to 90 °C and increased as temperature increased. Empirical correlations for the solubility and diffusivity at various temperatures were given.

Solubilities of Carbon Monoxide in Aromatic Hydrocarbons at Temperatures from 323 to 433 K and Pressures to 23.3 MPa

The solubilities of carbon monoxide in benzene, naphthalene, phenanthrene, and pyrene were measured using a static equilibrium cell over the temperature range from 323.2 to 433.2 N and pressures to 23.3 MPa. The uncertainty in these solubility measurements is estimated to be less than 0.001 in mole fraction. The data were analyzed using the Soave-Redlhich-Nwong (SRN) and Peng-Robinson (PR) equations of state (EOS). In general, the two equations represent the experimental data well over the complete temperature range when one interaction parameter is used for each binary system. Marginal improvements in equation of state predictions are realized when an additional interaction parameter is used

The solubilities of carbon monoxide in decane, eicosane, octacosane, and hexatriacontane were measured using a static equilibrium cell over the temperature range from 310.9 to 423.2 K and pressures to 10.2 MPa. The uncertainty in these new solubility measurements is estimated to be less than 0.001 in mole fraction. The data were analyzed using the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state. In general, two binary interaction parameters per isotherm are needed to describe the data adequately

Solubility of carbon monoxide in n-hexane between 293 and 473 K and carbon monoxide pressures up to 200 bar

The solubility of carbon monoxide, CO, in n-hexane was measured at 293, 323, 373, 423, and 473 K for CO partial pressures up to 200 bar. The enthalpy of solution was calculated between 293 and 473 K. Using the Krichevsky-Ilinskaya equation of state, the solubility of CO in n-hexane can be calculated between 293 and 423 K for CO partial pressures up to 200 bar with an accuracy better than 5%.

Correlation of solubilities of carbon monoxide, carbon dioxide, and hydrogen in paraffins.

A lattice-gas model is used for calculating Henry’s constants of binary mixtures of light gases in normal paraffins. The results, compared with experimental Henry’s constants, have an error of around 10%. The paper shows the possibility of predicting gas solubility in normal paraffin using a binary parameter obtained in the process of correlating Henry’s constants.

Solubility of Gases in Liquids. 15. High‐Precision Determination of Henry Coefficients for Carbon Monoxide in Liquid Water at 278 to 323 K

AbstractThe solubility of carbon monoxide in pure liquid water was measured in the pressure range 60 to 110 kPa and the temperature range 278 to 323 K with a high‐precision apparatus of the Benson‐Krause type. These data are used to derive Henry coefficients H2, 1(T, Ps, 1), the temperature dependence of which is accounted for by both a Clarke‐Glew type fitting equation and a power series in T−1. The imprecision of our measurements is characterized by an average deviation of H2, 1(T, Ps, 1) from these smoothing equations of about ±0.04%. From the temperature variation of H2, 1(T, Ps, 1) the partial molar quantities pertaining to the solution process (such as standard changes in enthalpy and heat capacity) are obtained. In addition, Ostwald coefficients are given in tabular form at rounded temperatures. Experimental results are compared with values calculated via scaled particle theory.

Hydroformylation with supported liquid phase rhodium catalysts Part II. The location of the catalytic sites

Hydridocarbonyltris(triphenylphosphine)rhodium(I), dissolved in triphenylphosphine and capillary condensed into the pores of a support, is applied in the catalytic heterogeneous hydroformylation of ethylene and propylene. Catalysts with triphenylphosphine in the liquid and in the solid state, do not show any difference in apparent activation energy and catalytic activity. From this it follows that we are dealing with a case of heterogeneous catalysis, i.e. that only the rhodium complexes at the gas-triphenylphosphine phase boundary are involved in the reaction. The inactivity of the rhodium complexes outside the phase boundary is most likely due to high coordination of these complexes with free triphenylphosphine molecules, and to the very low solubility of carbon monoxide in triphenylphosphine, and not to an extreme liquid-phase diffusional retardation of the rate of reaction.

Carbon Isotope Separation by Absorptive Distillation

Abstract The feasibility of separating carbon isotopes by absorptive distillation has been studied for CO absorption by cryogenic solvents. Phase equilibrium, isotopic separation, and mass transfer data were taken between 77.4 and 114.3 K for the following solvents: propane, propylene, 1:1 propane-propylene, 1-butene, isobutane and nitrogen. Carbon monoxide solubility followed Henry's Law, with a maximum experimental solubility of 6.5 mole per cent. Isotopic separation between CO in the gas and liquid phases using hydrocarbon solvents was several times that for pure CO vapor-liquid equilibrium. The maximum observed isotopic separation factor was 1.029 at 77.4 K with the propane-propylene solvent mixture. Mass transfer measurements yielded calculated HTU's of 2 to 5 cm for a possible separation system. An attempt has been made to correlate isotopic separation data using Hildebrand's theory of solutions. The differential absorption of isotopic CO species is expressed as a difference in solubility of the iso...
