Concepts of fundamental processes related to gasification of coal. Quarterly progress report, October-December 1980
Progress reports for the following investigations are presented: (1) single stage catalytic coal gasification; (2) single stage coal gasification to high Btu gas; (3) reaction of aromatic compounds with steam. The objective of the first project is to optimize the process variables and catalyst systems to maximize methane yields. For project two, the objective 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 objectives for project three are: to develop a catalyst of suitable activity and sufficient life; to determine the conversion and approach to equilibrium as a function of the main variables of the reaction (temperature, pressure, contact time and steam/carbon ratio); to determine reaction mechanisms and kinetics of the reforming reactions. Some of the highlights for this quarter are: construction of the new high pressure laboratory has been sufficiently completed to allow the assembly of the coal gasification system; the stainless steel reactor vessel has been fabricated; thermodynamic feasibility study which involved pressure, temperature and steam percent in hydrogen feed, has been completed; hydrogen gas is now being analyzed by gas chromatography; liquids and unreacted solids are being analyzed for C,H,N; the experimental procedure has been standardized; the gas chromatogram has been refurbished for product analysis; a reactor has been designed which is separated into two zones (1) preheating and reaction, and (2) control and product analysis; a system for the preparation of catalyst for the reforming of aromatic compounds has been built.
