About 7 1/2 tons of SRC-II vacuum flash drum bottoms from the liquefaction of Powhatan coal were successfully gasified in a 12 ton per day pilot plant. The single fifteen hour run was completed at 24 atmospheres pressure. A 99.5 percent conversion of the carbon in the feed to syngas was achieved, yielding 33.4 SCF of dry syngas per pound of residue charged. The dry syngas contained about 90 (vol) percent carbon monoxide plus hydrogen. About three percent heavy distillate was added to the molten residue to reduce its viscosity to an acceptable level for handling in the pilot plant. Samples of all effluent streams were obtained and sent to Gulf Mineral Resources Company for detailed analyses. The short pilot plant run confirmed the operability of the Texaco Synthesis Gas Generation Process with this feedstock, and the data obtained confirm earlier predictions of performance efficiency. The run consisted of two Type II Preliminary Pilot Plant Evaluations run back to back, thus achieving a single run of twice the normal on stream time for a Type II Evaluation.
