摘要： Carbon monoxide is removed from feedstreams by a process which comprises contacting the feedstream with a solution of a cuprous fluorinated acetylacetonate in an organic solvent containing a stabilizing agent to remove CO by forming a first cuprous complex, decomposing the first cuprous complex whereby the stabilizing agent which replaces CO in the first cuprous complex to form a second cuprous complex, and separating the displaced CO. The formation of the second cuprous complex avoids any deposition of copper metal upon heating.

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： 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.
