Title: Effect of pretreating of host oil on coprocessing. Quarterly progress report, April 1, 1993--June 30, 1993

Abstract

The principal objective of this research is to gain information on the role that host petroleum-derived oils (1000 F+), as well as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The host oil will be extensively characterized and then pretreated in a number of ways which involve catalytic reactions such as hydrogenation, hydrocracking, and isomerization. The pretreated oils will then be characterized by elemental analysis, catalytic dehydrogenation, distillation, GC-MS, and NMR. The effects of the host oil on coprocessing with coal will be compared to those obtained using catalytically modified heavy oils. When appropriate, model compounds will be used to study specific reactions brought about by the pretreatments. In the progress report for January, 1993--March, 1993, we concluded that the dispersed iron based catalysts were not effective in hydrotreating the AMOCO VTR at 400{degree}C. During the second quarter of this year, several pretreatment runs were conducted at 440{degree}C using molybdenum naphthenate, a known active hydrotreatment catalyst. The reaction time was increased from one hour to two hours, during which time the reaction pressure leveled off. hen Mo naphthenate was added at a concentration of 500 ppM of Mo, coke production was drasticallymore » reduced, to less than 3%. Gas production was also reduced which resulted in higher oil (pentane soluble) yields. At a higher catalyst loading of 2,000 ppM of Mo there was little change to the products, the asphaltene content decreasing slightly. This indicates that a catalyst loading of 500 ppM of Mo is probably sufficient for hydrotreating the AMOCO VTR, and there is little benefit in increasing the loading to 2000 ppM.« less
