X-ray scattering intensities have been obtained of seven vitrinites of different rank and a natural graphite before and after treatment with lithium in ethylenediamine. Scattering intensities showed extensive changes in the arrangement of carbon atom

A petroleum vacuum resid (1,000 F+) was pretreated by catalytic hydrogenation and hydrocracking reactions and the pretreated resids (host oils) were then coprocessed with coal. The fraction of coal converted to soluble products and the yield of penta

The use of solid acids, especially Pt/ZrO{sub 2}/SO{sub 4}, to convert long chain alkanes and Fischer-Tropsch waxes to liquid fuels under mild reaction conditions was explored in this work. Anion and/or hydrogenation metal modified zirconium oxides w

In this quarter we studied the effect of hydrogen pressure, and of sulfur and nitrogen containing compounds on the isomerization and hydrocracking of n-hexadecane using a Pt/ZrO{sub 2}/SO{sub 4} catalyst. The reactions were carried out at 300{degrees

The principal objective of this research is to gain information on the role that host petroleum-derived oils (1000{degrees}F+), as well as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The

Work in the proceeding quarter focussed on the kinetic modeling of isomerization and hydrocracking reactions of long-chain paraffins over a Pt/ZrO{sub 2}/SO{sub 4} catalyst. The model is based on a simplified reaction network. The effects of hydrogen

In the last quarterly report we presented results of coprocessing runs made with an Illinois No. 6 coal and an AMOCO VTR (as received) and after the heavy oil had been pretreated a number of different ways. Coal conversions and product yields were pr

This study demonstrated the feasibility of using catalytic dehydrogenation for the examination of direct coal liquefaction process-derived materials. The technique, which was developed for the examination of coals, was applied to the 850{degrees}F{su

During the last quarter we characterized the acidity of platinum-promoted solid superacids by TPD (temperature-programmed desorption) and investigated the effect of sulfate concentration on the activity of Pt/ZrO{sub 2}/SO{sub 4} catalysts for isomer

A bench-scale reactor is being used to conduct studies of the conversion of synthesis gas to methanol (MeOH) in the liquid phase by a novel process. In previous report, we provided evidence for a two step reaction in series, the carbonylation reactio
