The carbon four liquefied gas is used as an important petroleum resource, and has an increasingly important role in the field of chemical production. The comprehensive utilization way of the C4 is also wider, wherein the synthesis of methyl tertiary butyl ether by the reaction of isobutene in the C4 hydrocarbon and methanol is the main way of the C4 utilization in China at present. The carbon four raw material with high isobutene content required by the etherification reaction of the carbon four device is obtained by butene isomerization reaction. The conversion of the isomerization directly affects the isobutylene content in the etherification feed carbon four. And 1.3-butadiene can accelerate coking speed of the isomerization catalyst, reduce catalyst activity and increase production cost of the device. In order to reduce the effect of 1.3-butadiene on the isomerization catalyst, it is desirable that 1.3-butadiene in the feed carbon four be converted to 1-butene by a hydrogenation process. The four carbon devices currently adopt palladium catalysts as catalysts for the hydrogenation conversion of 1.3-butadiene, and in order to ensure the hydrogenation effect of 1.3-butadiene, the pressure of a hydrogenation system needs to be controlled at 1.45Mpa, so that the efficiency of the existing devices is lower, the power consumption is higher, and the production cost of the devices is increased.
