摘要： A process for the combined hydrodesulfurization and hydroconversion of certain heavy hydrocarbon feedstocks is disclosed. Specifically, asphaltene-containing feedstocks, such as residua feedstocks, are initially contacted with a hydrodesulfurization catalyst which selectively avoids the conversion of the asphaltene agglomerates and metal-containing compounds therein, so that said feedstock is at least partially desulfurized, and then is contacted with an alkali metal in a conversion zone at elevated temperatures and in the presence of added hydrogen so that said feedstock is both further desulfurized and hydroconverted, preferably so that at least about 50 percent of the 1050.degree.F+ portion of the feedstock is converted to lower boiling products. In this manner the catalyst is maintained for long periods, while at the same time advantage is taken of the ability of the alkali metal desulfurization agent to both desulfurize and upgrade the hydrocarbon feedstock by the hydroconversion of the higher boiling components thereof.

摘要： The present invention relates to a process for desulfurizing heavy oil feedstreams with alkali metal compounds and improving the compatibility of the to stream components in either the feed stream, an intermediate product stream, and/or the reaction product stream in the desulfurization process. The present invention utilizes a high stability aromatic-containing stream that is preferably added to the heavy oil prior to reaction with the alkali metal compounds. The resulting stream resists precipitation of reaction solids in the desulfurization reactors. Even more preferably, the desulfurization system employs at least two desulfurization reactors in series flow wherein the high stability aromatic-containing stream is contacted with the reaction product from the first reactor prior to the second reactor, wherein the first reactor can be operated at a higher severity than without the use of the high stability aromatic-containing component stream.

摘要： The invention relates to an integrated, continuous process for the removal of organically bound sulfur (e.g., mercaptans, sulfides and thiophenes) comprising the steps of contacting a heavy oil, sodium hydroxide, hydrogen and water at a temperature of from about 380.degree. C. to 450.degree. C. to partially desulfurize the heavy oil and to form sodium sulfide, contacting said sodium sulfide with a transition metal in water to form a transition metal sulfide, sodium hydroxide and hydrogen. The sodium hydroxide is recirculated and the transition metal sulfide is removed. The partially desulfurized, dewatered heavy oil is treated with sodium metal under desulfurizing conditions, typically at a temperature of from about 340.degree. C. to about 450.degree. C., under a hydrogen pressure of at least about 50 psi to essentially desulfurize the oil, and form sodium sulfide. Optionally, the sodium salt generated can be regenerated to sodium metal using regeneration technology. The process advantageously produces essentially sulfur-free product oils having reduced nitrogen, oxygen and metals contents and reduced viscosity, density, molecular weight and heavy ends.

摘要： Improved processes for the combined desulfurization and hydroconversion of various sulfur-containing pertroleum oils, and particularly various residua feedstocks, are disclosed. These feedstocks are thus contacted with alkali metals, such as sodium, in the molten state, in a conversion zone maintained at specified conditions such that the feedstocks are both desulfurized and subjected to significant hydroconversion, particularly demonstrated by significant reductions in the 1,050.degree. F+ fraction of these feedstocks, as well as significantly decreased Conradson carbon and increased API gravity. In addition, the deep demetallization and moderate denitrogenation of these feedstocks is also achieved. These important results are obtained by maintaining the conversion zone at temperatures of above 750.degree. F, and in the presence of sufficient added hydrogen to produce a hydrogen pressure in the conversion zone of between about 1500 and 3000 psig.

摘要： The present invention relates to a process for removing sulfur from sulfur-containing hydrocarbon streams utilizing a multi-ring aromatic hydrocarbon complex containing an alkali metal ion. Preferably, the sulfur-containing hydrocarbon stream is comprised of high molecular weight hydrocarbons, such as a low API gravity, high viscosity crude, tar sands bitumen, an oil derived from shale, or heavy refinery intermediate stocks such as atmospheric resids or vacuum resids which are typically difficult to desulfurize and contain relatively high amounts of sulfur. However, intermediate refinery streams and refinery product streams may also be treated by the process of the current invention to achieve very low sulfur concentrations to meet environmental specification for fuels sulfur content.
