Abstract: Process for the complete saturation of a stream containing C2 to C4 hydrocarbons by hydrogenating such in a trickle phase over a fixed bed noble metal catalyst in the presence of a hydrogen atmosphere wherein about 0.3 to 3 parts of hydrogenation products per part of fresh feed are recycled in the process.

Abstract: 1,126,848. Selectively hydrogenating C 4 hydrocarbons. FARBENFABRIKEN BAYER A.G. 8 May, 1967 [15 June, 1966], No. 21328/67. Heading C5E. C 4 -hydrocarbon mixtures containing butadiene and n-but-1-ene are selectively hydrogenated to obtain butadiene-poor C 4 fractions with high n-but-2-ene content and diminished n-but-1-ene content by passing the liquid C 4 charge in a descending stream over a catalyst fixedly arranged in the reaction zone in a hydrogen atmosphere at an inlet temperature of 10-35‹C. and an outlet temperature of 60-90‹ C. The butadiene content may be reduced to less than 0À1% by volume and butane is formed only in small quantities. A group VIII metal, e.g. Pd, may be used in a catalyst in amount 0À01-1% by wt. of the catalyst. The catalyst support may contain 20% of lithium aluminium spinel and have a specific surface of 10-100 m 2 /g. A hydrogen pressure of 7 to 20 atmospheres is preferred.

Abstract: 1,149,093. Propane. FARBENFABRIKEN BAYER A.G. 9 May, 1966 [8 May, 1965], No. 20482/66. Heading C5E. [Also in Division B1] Unsaturated hydrocarbons in a C 3 -phase (mainly propylene, but may contain small amounts of allene and methyl acetylene) are completely hydrogenated to propane in the liquid phase over a noble metal catalyst in a practically stationary atmosphere of hydrogen. The process is preferably in the trickle-phase. The catalyst may be platinum or palladium on a support, e.g. alumina and/or an aluminium spinel, the spinel-forming metal being Li, Be, Mg, Mn, Cu or Ni. The reaction product is preferably recycled through the process in an amount of 0À3-3À0 parts per part of fresh feed. Suitable hydrogenation conditions are: temp. 10-75‹ C., pressure 10-50 atm. gauge, and feed throughput 2-20 kg/litre of catalyst.
