An ethanol dehydration process is provided in which the steam to ethanol ratio is between about 1.0 to 2.0 wt/wt and preferably about 1.5 wt/wt. Steam can be imported from outside the dehydration process such as from an oligomerization or dimerization reaction.

Steam integration in ethanol to jet fuel process

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.

Ethanol to ethylene process

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.
