Concepts of fundamental processes related to gasification of coal. Quarterly progress report, January-March 1981
The primary objective of the research on single stage catalytic coal gasification is to optimize the process variables and catalyst systems to maximize yields. The -200 mesh coal will be slurried in a hydrogen donor solvent, tetralin in a ratio of 2 parts solvent to 1 part coal by weight, and initially a sulfided Ni-W/SiO/sub 2/-Al/sub 2/O/sub 3/ catalyst will be used. All of the required equipment has arrived and the system is undergoing pressure testing and some minor redesign. The objective of the project on single stage coal gasification to high Btu gas is to investigate the potential for obtaining high methane yields by direct catalytic hydrogenation of coal in a single stage with a maximum temperature of 550/sup 0/C. The work completed so far has included a thermodynamic feasibility study which involved investigating the effect of various parameters, temperature, pressure, and steam percent in hydrogen feed. Fifteen experimental runs have been completed
