Abstract: A process for hydrotreating a hydrocarbon feedstock, such as light cycle oil, using a catalyst composition containing a hydrogenation/dehydrogenation component and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. The hydrotreating process removes contaminants, such as sulfur and/or nitrogen, from the feedstock.

Abstract: Petroleum wax feeds are converted to high Viscosity Index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity dicarboxylic acid-treated zeolite Beta or mordenite catalyst which effects a preferential isomerization on the paraffin components to less waxy, high V.I. isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig.

Abstract: There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons including C.sub.5 + liquid hydrocarbons are produced. The catalyst used in this reaction may be a ZSM-5 catalyst. The process involves the use of an initial cofeed, such as propane, in admixture with the methane and oxygen to induce the formation of liquid hydrocarbons. As the reaction progresses, the flow of cofeed is shut off, and liquid hydrocarbons continue to be produced.

Abstract: A mixture of organic compounds comprising a major amount of liquid hydrocarbons, mostly aromatic, is formed by the direct partial oxidation of methane in the presence of a ZSM-5 catalyst. The reaction conditions are substantially the same as those required for the direct homogeneous partial oxidation to methanol. However, liquid hydrocarbon formation depends on the presence of a small amount of an impurity such as propane or propylene in the feed; in the absence of such, only methanol is formed. With such modifier present, controls of reaction parameters, e.g., temperature, permits synthesis of both methanol and liquid hydrocarbons in desired proportions. Properly processed natural gas can serve to provide methane and at least part of the reaction modifier.
