Abstract: A process for producing acetylene, ethylene, or both is disclosed. The process includes combusting a fuel stream to produce a combustion gas effluent stream and pyrolyzing a feed stream in a pyrolysis zone in the presence of the combustion gas effluent stream to produce a pyrolysis zone effluent stream which is further quenched and compressed. The compressed quenched stream is separated in a solvent separation column to produce a net gas stream comprising hydrogen, methane, and at least one carbon oxide and a product stream. A portion of the carbon oxide of the net gas stream is converted into methane in a methanation reactor and a reactor effluent stream is sent to an amine scrubber where carbon dioxide is removed and a methane containing stream is generated as an effluent. The methane containing stream is then recycled to the pyrolysis zone of the supersonic reactor.

Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which subjects oligomerized product to hydrocracking and perhaps hydroisomerization to convert heavier oligomers to jet fuel range oligomers. A jet fuel product stream may be taken from a side of a stripping column which produces a heavy drag stream from a bottom of the stripping column to ensure an end point boiling specification is achieved.

Abstract: An integrated process for hydrogenating olefins wherein the hydrogen stream is generated from electrolysis of water is described. Water is derived from a first reaction step wherein a first feed stream comprising oxygenated hydrocarbons is reacted to produce a first reacted product stream comprising olefins and a second reacted product stream comprising water. The second reacted product stream is electrolyzed to produce an electrolyzer product stream comprising hydrogen. Hydrogen is used to hydrogenate olefins. A paraffin stream can be obtained from the hydrogenated effluent.

CPC classification number: C07C5/333 , B01J19/0053
Abstract: A new process and apparatus for ethanol dehydration combines a fired heater with a dehydration reactor in a single vessel. The reactor provides catalyst tubes in a firebox. The catalyst may be added to and withdrawn from the catalyst tubes. The apparatus reduces equipment account substantially while holding the reaction to isothermal conditions.

Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which manages the dimerization exotherm by diluting it with paraffins which are inert in the dimerization. The olefin stream can also be split and fed to multiple dimerization reactors to further reduce the heat generated. The ethylene feed can also be cooled before entering the dimerization reactor. The paraffins can be obtained from saturating oligomerized effluent.
