Reitz,

A series of experiments carried out in a DHD chamber containing a sequence of four 10-liter ovens are described. The experiments alternated among 20- and 60-minute cycles, 0.5 and 1.0 kg/1/hr catalyst throughput, catalysts K6108 (Terrana) and K6752 (synthetic aluminum silicate), and various temperatures from about 400/sup 0/C to about 480/sup 0/C. They operated on a prehydrogenation middle oil from bituminous coalliquefaction and on two petroleum middle oils. The products of the process were distilled into fractions boiling up to 150/sup 0/C (gasoline) from 150/sup 0/C to 180/sup 0/C (heavy gasoline or middle oil), and past 180/sup 0/C (residue). Data about each of the experiments were tabulated and presented in graphical form. Information collected included compositions of the various fractions including gaseous fractions, aniline points, iodine numbers, octane and cetane numbers. Some of the graphs showed changes in these values with changing temperature of reaction, and others showed changes in the values through the sequence of experimental cycles or through the course of one cycle. The aluminum silicate seemed to be a much more active catalyst than the Terrana. Even at a much lower temperature than for Terrana, the aluminum silicate gave almost twice as much gasoline. Aluminum silicate gave lower iodine numbers and better octane numbers. 5 tables, 11 diagrams
