| titleOfInvention | Method for double bond isomerization of butane |
| abstract | The invention relates to a method for double bond isomerization of butane. According to the method, the technical problems of low selectivity of a reaction product and short catalyst activity period in the prior art are mainly solved. The method disclosed by the invention comprises the following step that raw materials containing the butane and a catalyst are contacted and react to generate an effluent which containing butane-1 and butane-2 and the mol ratio of the butane-1 to the butane-2 approaches to a thermodynamic equilibrium value under the conditions that the reaction temperature is 100-450DEG C, the reaction pressure is -0.08MPa to 10MPa and the weight space velocity is 0.1-100h<-1>, wherein the used catalyst comprises the following components in percentage by weight: (a) 50-95 percent of ZSM molecular sieve of which the silicon-aluminum mol ratio of SiO2 to Al2O3 is 40-1000; (b) 0.001-6 percent of alkaline-earth metal elements or oxides thereof loaded on the ZSM molecular sieve; and (c) 5-50 percent of bonding agent. According to the technical scheme, the problems are solved. The method can be used for industrial production of the double bound isomerization of the butane. |
