Abstract: An improved ebullated bed hydroconversion process is disclosed that utilizes a bimodal heterogeneous catalyst and a metal containing oil-miscible-catalysts compound to achieve a reduction in sediment, an increase in conversion, a reduction in the energy utilized to maintain reaction conditions and increases the stability of the ebullated catalyst bed. The oil-miscible compound may be provided in a concentration so as to provide about 1 to about 60 wppm metal based on the charge hydrocarbon oil.

Abstract: Naphtha is selectively hydrodesulfurized using spent resid upgrading catalyst to remove sulfur while minimizing loss in octane level due to olefin saturation.

Abstract: A method of catalytically hydroconverting a hydrocarbon feed stream containing a substantial quantity of components boiling above about 1000.degree. F. to convert a substantial portion thereof to components boiling below 1000.degree. F. is disclosed. More particularly, aromatic heavy oil additive, such as Heavy Cycle Gas Oil, is added to a heavy hydrocarbon feed stream and the stream is contacted with a solid catalyst and an oil-miscible metal naphthenate. The method disclosed herein advantageously substantially eliminates plugging of the hydroconversion reactor and minimizes the amount of insolubles in the total liquid product.

Abstract: A waste molybdenum-containing stream recovered from the work-up of a reaction mixture wherein propylene has reacted with t-butyl hydroperoxide to form propylene oxide (in the presence of a complex of ethylene glycol and a molybdenum compound) is passed as an oil-miscible/soluble molybdenum-containing catalyst to a reaction wherein heavy hydrocarbon is hydroconverted to lower boiling products in the presence of heterogeneous catalyst.
