Amoco is developing and evaluating catalysts and process improvements for coal liquefaction in the two-stage close-coupled catalytic process. The project is being done under contract to the United States Department of Energy. Bench-scale beneficiation of Martin Lake lignite and Illinois No. 6 coal was completed in the preparation of low-ash samples for testing as liquefaction feedstocks. Size separation in combination with gravity beneficiation was effective in beneficiating Illinois No. 6 coal, as demonstrated by liquefaction runs made in the AU-51 flow unit. In the case of Martin Lake lignite, size separation in combination with aqueous sulfur dioxide treatment followed by density separation was shown to be effective in preparing a liquefaction feedstock. Second-stage catalyst testing is continuing. AMOCAT{sup {trademark}}-1C had previously been shown to outperform catalysts prepared using Cabot-based aluminas for denitrogenation, Ramscarbon removal, and conversion of coal resid. Commercial catalysts including UOP`s RCM-4, Idemitsu`s zeolite-containing catalyst, Shell 324, and Topsoe`s TK-771 are about as active as AMOCAT{sup {trademark}}-1C for resid and Ramsbottom conversions. However, both Shell 324 and Topsoe`s TK-771 are more active than AMOCAT{sup {trademark}}-1C for denitrogenation. A ruthenium-promoted version of AMOCAT{sup {trademark}}-1A prepared at SRI was no more active than AMOCAT{sup {trademark}}-1C. Future work will include continuous liquefaction runs with the samples of beneficiated lignite and base-line run with Illinois No. 6 coal. Catalyst testing in the Miniager will continue with the evaluation of novel catalysts.
