| titleOfInvention | Method for preparing 2-butene through 1-butene double bond isomerization |
| abstract | The present invention relates to a method for preparing 2-butene through 1-butene double bond isomerization, wherein problems of low target product yield and poor stability in the prior art are mainly solved with the present invention. The technical scheme comprises that C4 olefin is adopted as a raw material, and the raw material passes through a catalyst bed layer at a reaction temperature of 200-450 DEG C under a reaction pressure (calculated as absolute pressure) of 0-5 MPa at a weight space velocity of 1-50 h<-1> to produce 2-butene, wherein a specific surface area of the catalyst is 200-1000 m<2>/g, a pore volume is 0.3-1.0 m<3>/g, an average pore size is 6-12 nm, and a surface alkaline site concentration is 0.3-10.0 mumol/g. With the technical scheme, the problems in the prior art are well solved, and the method can be used for industrial production of 2-butene preparation through 1-butene double bond isomerization. |
