Abstract: A method and a system for recovering hydrogen from a process for making hydrogen cyanide are described herein. In the method, hydrogen is recovered from a gaseous waste stream of an Andrussow process. The method comprises the following steps: (a) adjusting a reaction mixture comprising methane, ammonia and oxygen to provide the reaction mixture with sufficient oxygen to generate a gaseous waste stream that has at least 40% hydrogen after removal of ammonia and recovery of hydrogen cyanide; and(b) removing components from the gaseous waste stream to generate recovered hydrogen.

Abstract: The present invention provides a method for preparing a foam that includes a polyurethaneurea dispersion. These foams have enhanced flexibility and resistance to compressibility compared to convention polyurethane foam. These foams may also be made by a reaction injection molding process. The method includes preparing a shaped polyurethane foam article by: (a) providing a first composition comprising at least one polyol, a chain extender composition and a blowing agent; (b) providing a second composition comprising at least one of a diisocyanate, a capped glycol, and combinations thereof; (c) mixing the first composition and the second composition to form a reaction mixture into a heated mold; and (d) allowing the reaction mixture to form a polyurethane foam; wherein the first composition includes one of: (i) the chain extender composition includes at least one amine compound; (ii) the blowing agent includes a polyurethaneurea aqueous dispersion; and (iii) combinations of (i) and (ii).

Abstract: The following example is a method treating a cyclohexylhydroperoxide (CHHP) hydrogenation catalyst. A reactor is provided that is filled with a partially deactivated hydrogenation catalyst from a CHHP hydrogenation process. A regeneration stream is then fed into the reactor, wherein the regeneration stream is a portion of the product mixture from the CHHP hydrogenation process. The partially deactivated hydrogenation catalyst is then contacted with the regeneration stream and finally the used regeneration stream is recovered from the reactor.
