Summary
The principal objective of this program is to experimentally study the process variables and chemistry of the Flash Hydropyrolysis Process, a rapid gas-phase, non-catalytic coal hydrogenation technique developed at BNL for the conversion to gaseous and liquid fuels. The experimental equipment used for this purpose is a highly instrumented 1 inch down-flow tubular reactor originally designed to operate at up to 4000 psi and 800/sup 0/C, with coal feed up to 1 lb/hr. These conditions are being extended to include temperatures to 900/sup 0/C at pressures equal to or less than 2500 psi and coal feed to 2 lbs/hr. Coal and char analyses are performed on a routine basis. A second distillation curve was performed on the total organic liquid product, this time extending the distillation temperature range to 350/sup 0/C. The results were similar to the first curve indicating that the liquid contains approximately 50% BTX (benzene, toluene, xylene) and 50% heavier hydrocarbons. A major portion of the experimental effort was devoted to the study of the effect of coal particle residence time. A number of exploratory runs were also conducted and results are reported here, including the use of a Battelle Treated Coal (BTC-caking coal treated with CaO), a New Mexico sub-bituminous coal, a mixture of lignite and lignite char and a lignite impregnated with iron.
