Catalysts prepared by dispersing Ni, Mo, and combinations of Ni and Mo on the sodium form of hydrous oxides of titanium (HTO), zirconium (HZO), and niobium (HNO) by an ion exchange process were tested for use in direct coal liquefaction. Conversion of coal to oil, as measured by the amount of product having a molecular weight less than )similarreverse arrowto)250, was a function of the active metal used with Mo catalysts yielding higher conversions than Ni catalysts. Conversion was also proportional to the Mo/Ni atomic ratio for catalysts containing both metals. In contrast, hydrogen consumption for the liquefaction experiments was a function of not only the active metal (Ni, Mo), but also the hydrous metal oxide support (HZO, HNO, HTO). Comparison of the results for the hydrous metal oxide catalysts with those for a Ni-Mo/alumina catalyst demonstrated that the Mo hydrous metal oxides were as effective for conversion of coal and the Mo HZO catalyst consumed significantly less hydrogen. 8 refs., 1 figs. 1 tab.
