New catalysts for coal-liquid upgrading. Quarterly report, December 1, 1982-February 28, 1983
The objective of this project is to develop thermally stable, poison-tolerant catalysts that will be effective under moderate conditions in the hydrogenation or hydrodenitrogenation of nitrogen-containing heterocycles typical of coal liquids. The hydrogenation of model compounds, model compound mixtures and coal liquids will be carried out using the new class of catalysts, metallophthalocyanines (M(PC)). The initial screening of the catalysts will be done using quinoline as a substrate at 300 to 400/sup 0/C and pressure of 1000 to 3000 psi H/sub 2/. The most effective catalysts will then be selected and used in hydrogenation of other model compounds like pyridine, indole, carbazole and acridine, in the hydrogenation of model compound mixtures and then coal liquids. The model compound mixture to be used consists of phenanthrene, dibenzothiophene, dibutylsulphide, quinoline, dibenzofuran and p-cresol. Coal liquids from the H-Coal process will be subjected to hydrotreating. The activity of (M(PC))/SiO/sub 2/ in the hydrogenation of quinoline has been compared to that of the commercial catalysts and the results are reported here. Also experiments in the hydrogenation of the model compound mixture with various catalysts are reported. (LTN)
