A process for selective hydrogenation of acetylene during ethylene purification without in-situ prereduction utilizing a palladium/gold impregnated catalyst wherein the ratio of the gold to the palladium is from about 6:1 to about 50:1.

Process for selective hydrogenation of acetylene in an ethylene purification process

A process for selective hydrogenation of a C and C olefinic feed stream containing acetylenic and diolefinic impurities whereby the acetylenes and diolefins impurities are selectively hydrogenated concurrently in a vapor phase process without first separating the C and C olefinic gases into separate feed stream.

Process for selective hydrogenation of an olefinic feed stream containing acetylenic and diolefinic impurities

An adsorbent product for the adsorption of trace elements of sulfur, arsenic, mercury, compounds which contain these elements or metal hydrides from a hydrocarbon gas stream, preferably an olefinic or paraffinic stream, wherein the adsorbent product is iron oxide and manganese oxide placed on a support material, preferably aluminum oxide. Also disclosed is a process for the use of this adsorbent product for the removal of trace elements of arsenic, mercury and sulfur or compounds containing those elements or metal hydrides from a hydrocarbon gas stream, preferably an olefinic or paraffinic gas stream.

Adsorbent for the removal of trace quantities from a hydrocarbon stream and process for its use

Adsorbent for the removal of trace quantities from a hydrocarbon stream

An improved vapor phase catalytic hydrogenation of aldehydes to the corresponding alcohols wherein the improvement comprises employing a copper oxide-zinc oxide catalyst impregnated with a selectivity enhancer selected from the group consisting of an alkali-metal, transition metal and mixtures thereof.

Improved aldehyde hydrogenation process

An aldehyde hydrogenation catalyst consisting essentially of a mixture of copper and zinc oxide impregnated with a minor selectivity improving amount of a selectvity enhancer comprising the combination of an alkali metal selectivity enhancer selected from the group consisting of sodium, potassium, lithium, cesium, and mixtures thereof and a transition metal selectivity enhancer selected from the group consisting of nickel, cobalt, and mixtures thereof.
