Abstract: A process of converting an ethanol feed stream to ethylene comprising sending portions of said ethanol feed stream to two reactors in parallel and then sending the combined product to a third reactor that is operated at a higher temperature to prevent the formation of ethers such as diethyl ether.

Abstract: A process for oligomerizing olefins to distillate fuels which oligomerizes a recycle olefin stream with a charge olefin stream in a first-stage oligomerization reactor. The first-stage oligomerate is oligomerized in a second-stage oligomerzation reactor to provide a second-stage oligomerate stream. The second-stage oligomer stream is hydrogenated to produce fuels. A stripping column is used to prepare the hydrogenated fuel streams for fractionation.

Abstract: An integrated apparatus for hydrogenating olefins wherein the hydrogen stream is generated from the 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.

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 The catalyst may be added to and withdrawn from the catalyst tubes.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.
