  A composition comprising a supported hydrogenation catalyst comprising palladium and an organophosphorous compound, the supported hydrogenation catalyst being capable of selectively hydrogenating highly unsaturated hydrocarbons to unsaturated hydrocarbons. A method of making a selective hydrogenation catalyst comprising contacting a support with a palladium-containing compound to form a palladium supported composition, contacting the palladium supported composition with an organophosphorus compound to form a catalyst precursor, and reducing the catalyst precursor to form the catalyst. A method of selectively hydrogenating highly unsaturated hydrocarbons to an unsaturated hydrocarbon enriched composition comprising contacting a supported catalyst comprising palladium and an organophosphorous compound with a feed comprising highly unsaturated hydrocarbon under conditions suitable for hydrogenating at least a portion of the highly unsaturated hydrocarbon feed to form the unsaturated hydrocarbon enriched composition.

  The problem to be solved is to provide a process for producing a polyoxymethylene copolymer in a molding machine with a reduced generation of formaldehyde gas. In a process for continuously producing a polyoxymethylene copolymer comprising a step of melt-kneading a crude polyoxymethylene copolymer at a temperature not lower than the melting point thereof, devolatilizing under reduced pressure the formaldehyde gas generated as a decomposition product, subsequently mixing a formaldehyde scavenger containing a hydrazide compound (A) while keeping the copolymer in a molten state and immediately pelletizing the mixture, a dispersed solution obtained by slurry-dispersing said (A) in a diluent (B) having a melting point lower than temperature (Ta) which is the lower of the melting point and the decomposition temperature of (A), within a temperature range not lower than the melting point of (B) and lower than (Ta) is used as the formaldehyde scavenger.
