    摘要: A novel composition comprising zinc oxide and at least one metal phosphate that can be effectively used to remove sulfur compounds from a fluid stream by contacting said fluid stream under suitable absorption conditions with this novel composition. Also, a novel method is described for making a composition comprising mixing with zinc oxide at least one metal phosphate followed by the addition of a dilute acid to form a paste or paste like material having a desired consistency for agglomeration.

    摘要: Process for the hydrogenation of functionally substituted acetylenic compounds employing catalyst comprising nickel boride on an inorganic oxide support is disclosed. Functionally-substituted acetylenic compounds are selectively reduced under mild reaction conditions to give functionally-substituted cis-olefinic compounds in high yield.
