Abstract:

The carbonized resin w as prepared using strong acid cation exchange resin as the precursor .Using the carbonized resin as carrier , the carbonized resin supported PW₁₂ catalyst was prepared by loading PW₁₂ on the carbonized resin .Effect of activation condition of the carbonized resin on the surface performance, loadings of PW₁₂and stability of PW₁₂ were investigated.The adsorption process of solid acid catalyst PW₁₂ on carbonized resin w as influenced.Research results show that activation of HNO₃ is better than that of HCl, H₂SO₄ and H₃PO₄ , and the optimal concentration of HNO₃ of the pretreatment solution is 4.5mol/L .The etherification of light catalytic cracking gasoline and methanol w as carried out under the conditions of reaction temperature is 70 ℃,methanol and olefin mole ratio is 1.1, pressure is 1 .0 MPa , LHSV is 1.0 h-1 .The conversion of tertiary carbonic olefin is up to 56.68 %, which is higher than that of D005 strong acid cation exchange resin catalyst.

摘要： 以大孔强酸性阳离子交换树脂为前驱体制备了炭化树脂, 以此为载体, 通过负载磷钨酸(PW_l2)制备了炭化树脂载磷钨酸催化剂。考察了炭化树脂活化条件对表面性能和磷钨酸负载量及负载牢固程度的影响。固体酸催化剂PW_l2在炭化树脂吸附过程中受预处理的影响。实验结果表明, HNO₃活化效果好于HCl、H₂SO₄和H₃PO₄, HNO₃ 处理液的最佳浓度为4.5 mol/ L。在反应温度为70 ℃、醇烯摩尔比为1 .1 、压力为1 .0 MPa 、空速为1.0 h^-1的条件下进行了催化裂化轻汽油与甲醇的醚化试验, 叔碳烯烃转化率达到56.68 %, 高于D005 阳离子交换树脂催化剂。
