New catalysts for coal-liquid upgrading. Quarterly report, June 1-August 31, 1982. [Tin phthalocyanine]
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 catalysts to be used are supported on silica (M(PC))SiO/sub 2/; where M = Mn, Fe, Co, Ni, Cu, Ag, Mg, Pb, Sn, Mo, Rh, Rd, Pt, Os, Ir. The reduced forms, M/sup 1//sub n/(M(PC))/SiO/sub 2/ where M/sup 1/ = Na or Li and n = 1 to 5, are to be prepared and their catalytic activity evaluated. 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. A number of supported catalysts of (Co(PC)) have been prepared at several metal loading levels with three supports and tested in the hydrogenation of quinoline to 1, 2, 3, 4 tetrahydroquinoline. Within the experimental error the support has no important effect on catalytic activity.
