Abstract
This paper is focused on researching the influence of process parameters of partial oxidation, such as quality of hydrocarbon raw materials that differ in their stock properties (especially boiling point and viscosity) on the composition of output gas (selectivity of the process), and also on the formation extent of soot which could be used as an excellent and valued sorbent CHEZACARB ® and/or filler in the rubber industry, e.g. for automotive tires. The effects of steam flow rate and the oxygen to raw material feed rate ratio is discussed as well. In addition, sensitivity of POX product composition depending on properties of different raw materials and reaction conditions were analysed in this study.
Highlights
An increased demand on hydrogen, which is essential for a deeper hydrorefining of petroleum oils to ensure better quality of motor fuels motivate research on partial oxidation (POX) of high-boiling hydrocarbons residues or alternative biomass waste[1,2,3,4]
The impact of both steam and oxygen ratio to hydrocarbon oils feed on selectivity of its partial oxidation (POX) of black and white oils with regard to the composition of gaseous product was investigated in this study
Based on pilot plant experiments, the paper describes basic parameters influence on selectivity of partial oxidation process
Summary
An increased demand on hydrogen, which is essential for a deeper hydrorefining of petroleum oils to ensure better quality of motor fuels (from the point of view of exhaust emissions) motivate research on partial oxidation (POX) of high-boiling hydrocarbons residues or alternative biomass waste[1,2,3,4]. The raw material is gasified in industrial plants[5] typically at temperatures above 1300 °C under pressure of 3.5 MPa. The performance of the operating unit enables production (in the reaction space of 1 m3) of 1500 m3 h–1 of synthesis gas of a typical composition (% vol.): H2 = 49.3; O2 = 6.8; CO = 46.0; CH4 = 0.2; (N2 + Ar) = 1.1; H2S = 0.7. Its production can be monitored by discharging a soot dispersion into water, which arises at product quench cooling by water after outlet from the POX reactor The impact of both steam and oxygen ratio to hydrocarbon oils feed on selectivity of its partial oxidation (POX) of black and white oils with regard to the composition of gaseous product was investigated in this study. The texture characteristics, specific surface area SBET and micropores volume Vmicro, were measured (by N2 sorption) using ASAP 2010 M, Micromeritics, Co., USA
