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 dehydration of an ethanol feed stream comprising sending said ethanol feed stream and steam to a radial flow reactor to contact a catalyst under reaction conditions and produce an effluent comprising ethylene. The use of a radial flow reactor eliminates concerns about pressure drops that may occur with conventional fixed bed downflow reactors.

Abstract: An ethanol dehydration process is disclosed. The process comprises adding an amount of steam to a feed to the dehydration reactor to provide a charge stream. The steam stream is mixed with the feed to the dehydration reactor such that the steam to ethanol ratio is between about 0.5 to about 5.0 wt/wt. The charge stream is passed to a dehydration reactor to produce a dehydrated stream. Steam can be imported from outside the dehydration process such as from an oligomerization or dimerization reaction. Steam can be produced from the dehydrated stream.

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.

Abstract: A process for dehydration of ethanol to produce ethylene is provided. Ethanol is dehydrated to produce ethylene and the subsequent conversion of ethylene to longer chain olefins and then their hydrogenation to produce long chain paraffins. In some embodiments, a split feed is employed to improve efficiency and a caustic wash column is eliminated. The advantages of the process include a lower requirement for steam and a reduction in the combined reactor volume of 30-40% when two reactors are used as compared to a single reactor.

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.
