Abstract: Process for the dehydrogenation of a hydrocarbon feed stream comprising steps of contacting the feed stream with a dehydrogenation catalyst in at least one dehydrogenation zone and reacting the feed stream to a hydrogen containing effluent stream;admixing to the effluent stream an oxygen containing atmosphere in at least one mixing zone;removing hydrogen from the effluent stream by reaction with oxygen in the oxygen containing atmosphere by contact with a hydrogen oxidation catalyst in at least one hydrogen removing zone,the improvement of which comprises employing massive forms of noble metals or alloys thereof as catalyst in the hydrogen removal zone.

Abstract: A monolithic, structured catalyst for the preparation of aldehydes. Alcohol is converted to a corresponding aldehyde by partial oxidation of the alcohol using the catalyst which includes an active catalytic material and a monolithic, inert carrier for the same. The active material includes oxides of molybdenum and oxides of chromium, vanadium, aluminum, iron, tungsten, manganese and mixtures thereof.

Abstract: The removal of sulphides from gas streams while using a solid absorbent containing tin, tin oxides or mixtures thereof and optionally a stabilizing component consisting of nickel, copper, cobalt, iron or oxides thereof takes place by contacting the sulphide-containing gas stream with the solid absorbent, which is expediently in the form of a carrier with the tin component and the stabilizing component; hereby the absorbent is sulphided and the gas stream desulphided. Subsequently the sulphided absorbents are regenerated by being contacted with a stream of steam. The regeneration process employed is substantially thermoneutral so that superheating and consequent sintering of the absorbent is avoided; moreover it is not necessary to operate at low temperatures, whereby the formation of sulphates as a by-product is avoided.

Abstract: A catalyst for the partial oxidation of an alcohol to a corresponding aldehyde. The catalyst includes a monolithic structured inert carrier and an active catalytic mixture of oxides of molybdenum and either chromium, vanadium, aluminum, iron, tungsten, manganese or mixtures thereof in a molar ratio of the molybdenum oxide to the other oxide or oxides of between 1 and 5. The catalyst has a reduced pressure drop compared to a particulate catalyst bed.
