Novel process for depolymerization of coal to C{sub 2}-C{sub 4} hydrocarbons. Final report, 1 September 1989--31 August 1993
A principal objective of this work was to study the conversion of coal to C{sub 2} {minus} C{sub 4} hydrocarbons in a two-stage reactor system. Coal was converted to liquids at 440{degrees}C in a stirred batch autoclave using tetralin as the hydrogen donor solvent. The liquids produced were separated from the unreacted coal and ash by filtration. The liquids were then fed into a second stage fixed bed reactor containing sulfided Ni-Mo/Al{sub 2}O{sub 3} and SiO{sub 2{minus}}Al{sub 2}O{sub 3} catalyst. The liquids were hydrocracked on the dual functional catalyst giving high yields of C{sub 2} {minus} C{sub 4}. hydrocarbons. The pressure was 1800 psi and the temperatures were in the range of 425 to 500{degrees}C. The kinetic parameters of the conversion of coal liquids to gases were determined. The activation energy was determined.
