Work in Catalyst Preparation and Screening was concerned with modification of product workup procedure and elimination or reduction of uncertainties in the analysis of data from batch autoclave screening runs. Toluene was substituted for benzene as a solvent in the product workup because of the health hazard associated with the use of benzene and was added to the product prior to filtration in order to expose both liquid and solid product to the solvent. The conversion was about the same, using either the old benzene or new toluene product workup. The Engelhard dry coal charging device was used in an attempt to eliminate uncertainties in the batch screening data analysis. After considerable experimentation, use of the charging device was abandoned because of problems with plugging, temperature upsets, and catalyst coking. The effort in Catalyst Aging Tests with Eastern and Western Coal was centered around preparation of enough liquefaction solvent for the DOE program. In the application of new catalysts to the H-Coal process work centered around the 500 pound batch Amocat-1A (CoMo) received from W.R. Grace Company Catalyst inspection data were acceptable and, according to a recent HRI report, the performance results of the 500 pound batch were equivalent to or better than those of an earlier experiment Amocat-1A that HRI tested. The batch of catalyst was also tested in our continuous flow pilot plant, but results were inconclusive since lined-out slurry oil contained unconverted coal particles.
