Chemistry of lignite liquefaction. Quarterly report, July--September 1976. [NiO--MoO/sub 3/--TiO/sub 2/; MoO/sub 3/--NiO--TiO/sub 2/--SiO/sub 2/; MoO/sub 3/--NiO--ZrO/sub 2/; MoO/sub 3/--NiO--Al/sub 2/O/sub 3/]
Studies in the separation of the major groups of SRL are now discontinued due to reaction of the ion exchange resin with the solvent, non-quantitative recovery of the sample from the ion exchange resin, and efforts under way at the Pittsburgh Energy Research Center to find an optimum procedure for this purpose. One of the two computerized methods of analysis for handling various types of input data has been developed to the point that laboratory uv data are being put into it. Additional more accurate laboratory data have been obtained on the basis set of 20 compounds. The initial inaccuracy occurred because of under-specification performance of the Cary 14 spectrophotometer. The machine was repaired and the data retaken. The one-liter batch autoclave studies are continuing, using catalysts for the upgrading of SRL. These were tested and the results reported herein are very interesting. They show comparable activity to the best of the commercial catalysts tested thus far, and have less surface area. They hold much promise for future development. The characteristics of the one-liter batch autoclave are given for temperature vs. time (to show the degree of temperature control), pressure vs. temperature (to illustrate gas consumption with temperature), and pressure vs. time (gas consumption with time). For the model compound reduction, the results for benzophenone and diphenylmethane are completed and given. For benzophenone, a combination of CO and H/sub 2/ is most effective and the CO reaction is promoted by base. Diphenylmethane is difficult to reduce under these conditions. For electron spin resonance work, the Bruker spectrometer is installed and operating, and a new vacuum line was constructed. The earlier results of the interaction of CO with MgO is being duplicated with some parts of the resultant signal not in agreement with earlier reported results.
