Solvent tailoring in coal liquefaction. Quarterly report, November 1982-February 1983
TL;DRAbstract
A simple kinetic model, including a first-order catalyst deactivation rate, was applied to the upgrading of coal-derived feedstocks prepared from two solvent-refined coal fractions. A catalyst deactivation mechanism was proposed which involves the adsorption and surface reaction of coke precursors on active catalytic sites. The effect of feedstock composition, temperature, and pressure on kinetic parameters and, in particular, the catalyst deactivation rate, was determined. 21 references, 6 figures, 7 tables.
