    摘要: A cobalt carbonyl phosphine complex useful for hydrogenation of cyclic polyenes to corresponding cyclic monoenes is prepared by reaction of dicobalt carbonyl and a phosphine compound in at least one non-oxygenated aliphatic solvent. Selective hydrogenation of the cyclic polyenes comprises an induction period during which the polyenes are contacted with the cobalt carbonyl complex catlayst under hydrogen pressure followed by decreasing the reaction temperature and pressure for a period of time sufficient to complete the hydrogenation.

    摘要: An adsorption method is disclosed for removal of acid gas from a sulfur compound stream. The method relates to a novel process to remove acid gas from a sulfur compound stream by adsorption on an adsorption media adsorbent followed by regeneration of the adsorption media after the adsorption capacity has been reached. The adsorption media comprises an activated alumina, which has been previously treated with one or more alkali metal compounds, one or more alkaline earth metal compounds, or a mixture thereof; and then regenerating the adsorbent after the adsorption capacity has been reached.

    摘要: A process for purifying a fluid stream contaminated with carbon dioxide is provided which comprises contacting, under conditions sufficient to substantially remove the contaminated carbon dioxide from the fluid stream which contains at least one C.sub.2 -C.sub.5 olefin such as ethylene or propylene, with a composition containing an oxygen-containing metal compound such as, for example, an alkaline earth metal hydroxide. The contacting is carried out in the presence of water.
