Abstract
Liquefaction of newsprint and cellulose in tetralin at 350°C and pressure of 1.07–2.51 MPa for 1 h resulted in their 37% and 40% by weight conversion to organic liquids, respectively. A significant amount of water was also formed. The gases produced consisted of mainly CH 4 and CO. The total amount of gases produced was about 3–5% of the original amount of solid charged to the reactor. A first order kinetic model was proposed for the conversion of newsprint and cellulose. Rate constants and Arrhenius parameters were also calculated. Material balance for the process showed a good correlation between the carbon and oxygen contents of the reactant solid and products. Data indicate that most of the hydrogen supplied to the products is supplied by the solvent (tetralin). Fractionation of liquid products show that a major portion can be classified as pentane-soluble and asphaltenes with negligible benzene-insoluble fraction. The molecular weight distribution of the three fractions for the liquids obtained from newsprint and cellulose liquefaction was determined by size exclusion chromatography.
