STUDY ON 2-BUTENE ISOMERIZATION TO 1-BUTENE

The effects of reaction parameters such as temperature,WHSV and pressure to isomerization of 2-butene with Zhong yuan C_4's cut fraction over silicate catalyst was investigated in a fixed bed reactor,and the stability and regeneration of the catalyst was discussed.Results showed that the catalyst has a high conversion of 2-butene and a high selectivity to 1-butene at reaction conditions of 250- 300℃,WHSV 6-15 h~(-1),pressure 0.5-2.0 MPa.The catalyst had been run steadily for 1 800 h without regeneration.3×10~4 t/a isomerization industrial test of 2-butene showed that the reactivity and stability of the catalyst is excellent.The catalyst has high yield and high selectivity of 1-butene at high WHSV and long catalyst regeneration period.
