A catalyst for oxidative dehydrogenation of butene and a method for producing the same are described. The method includes forming a first coprecipitate, forming a second coprecipitate, and mixing the first and second coprecipitates under conditions that product a catalyst having a favorable surface chemistry profile.

Method for producing a catalyst for oxidative dehydrogenation of butene

The present invention relates to a catalyst for oxidative dehydrogenation of butene and a method for producing the same. The catalyst for oxidative dehydrogenation of butene has a large amount of Mo&#x2014;Bi phase acting as a reaction active phase on the surface, and therefore, can exhibit high catalytic activity, high conversion rate and high butadiene selectivity in the oxidative dehydrogenation of butene.

Catalyst for oxidative dehydrogenation of butene and method for producing the same

The present specification provides a ferrite catalyst, a method for preparing the same and a method for preparing butadiene using the same.

Ferrite-based catalyst, preparation method therefor, and method for preparing butadiene using same

A method of preparing butadiene and a device for preparing the same. The method includes passing reaction raw materials containing butene, oxygen, steam, and a diluent gas through an oxidative dehydrogenation reactor, and oxidative dehydrogenation is performed therein to produce a reaction product separating water from the reaction product condensing hydrocarbons to produce a crude hydrocarbon mixture; and separating butadiene from the crude hydrocarbon mixture, where a gas containing n-butane remaining after the butadiene is separated is fed into the oxidative dehydrogenation reactor, and butane is used as a diluent gas. Because butane is used as a diluent gas, a C4 mixture and gas products may be easily separated through cooling and condensation processes. Thus, the method may increase productivity while reducing energy consumption and raw material costs, thereby improving economic efficiency.

Method of preparing butadiene

Disclosed herein is a micro-channel reactor formed by placing a planar upper plate and a planar lower plate, each having a channel formed therein, such that the upper plate and the lower plate face each other, wherein the channel includes one or more introduction channels, into which different fluids are introduced respectively, a mixing channel, along which the fluids introduced into the introduction channels flow in a state in which the fluids join each other, and a discharge channel, from which the fluids joining in the mixing channel are discharged, the mixing channel includes a stem channel extending from the introduction channels to the discharge channel and one or more branch channels that diverge from the stem channel and are then interrupted, and, when the fluids are mixed through repetitive diverging and joining, the fluids diverge in upward and downward directions and then join each other in leftward and rightward directions.

Micro-channel reactor
