摘要
对于苯体积分数为1%～2%的汽油,采用苯烃化技术可显著降低汽油中的苯含量。在小型固定流化床试验装置上,采用自制的催化剂,考察了汽油苯烃化反应的影响因素并确定了优化的反应条件:反应温度250℃,反应压力1MPa(表压),汽油空速1.0h-1,烯/苯摩尔比6～7。在优化的反应条件下,汽油中的苯含量可降低45%。
The content of benzene can remarkably be reduced from gasoline by benzene alkylation technology with original volume fraction of 1% -2%. The effect of operating parameters on benzene alkylation process are discussed with self-made catalyst in a confined fluidized bed reactor. The result show that the content of benzene from gasoline can be reduced by 45 %, which under the optimal reaction conditions：reaction temperature of 250℃, reaction pressure of 1 MPa （g） ,space velocity of 1.0 h^-1 ,the molar ratio of ethylene to benzene,6 -7.
