    摘要: The present invention relates to a process for desulfurizing bitumen and other heavy oils such as low API gravity, high viscosity crudes, tar sands bitumen, or shale oils with alkali metal compounds under conditions to promote in-situ regeneration of the alkali metal compounds. The present invention employs the use of superheated water and hydrogen under conditions to improve the desulfurization and alkali metal hydroxide regeneration kinetics at sub-critical temperatures.

    摘要: Basically, the present invention is predicated on the discovery that zeolites that have a high silica to alumina ratio, e.g., a ratio of 20 and above, pore diameters of greater than about 5.0.ANG., and which have substantially no active acid sites, i.e., zeolites which are non-reactive toward olefin isomerization and oligomerization, are especially useful in substantially separating linear olefins and paraffins from hydrocarbon mixtures containing at least linear and branched aliphatic hydrocarbons and optionally containing aromatic and other hydrocarbons.

    摘要: Carbon dioxide containing acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an aqueous amine solution, wherein the amine consists of at least about 50 mol % of a sterically hindered amino alcohol and at least about 10 mol % of a tertiary amino alcohol, wherein said sterically hindered amino alcohol contains at least one secondary amino group which is part of a ring and is attached to either a secondary or tertiary carbon atom or a primary amino group attached to a tertiary carbon atom. The coaction of the sterically hindered amino alcohol and the tertiary amino alcohol provide an increase in the amount of carbon dioxide containing acidic gases absorbed compared to the use of the sterically hindered amines alone and lowers the heat of reaction.

    摘要: The invention relates to a process for treating naphthenic acid--containing whole crudes or fractions thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fraction at a temperature of from about 50.degree. C. to 350.degree. C. with a neutralizing amount of tetraalkylammonium hydroxide, preferably tetramethyl-ammonium hydroxide. The process has the additional benefits of reducing materials handling problems associated with treating oils using liquid solvents and in reducing emulsion formation.
