通过对不同反应温度下醛氨缩合反应催化剂Co-ZSM-5分子筛的比表面积、孔体积、平均孔径、催化活性及积炭的研究中发现,在其它条件不变时,反应温度范围在400-500℃,尤其当反应温度为450℃时,醛氨缩合反应对催化剂的固相性质影响较小,比表面积(221.95m2/g)、孔体积(0.2491cm3/g)较大,一定水平的平均孔径(4.49nm),较低的积炭量(11.92%),较高的烷基吡啶收率(70.94%)。
Through the study of the specific surface area, pore volume, average pore diameter, catalytic activity and carbon deposition of aldimine condensation reaction catalyst Al-Ammoniation reaction catalyst under different reaction temperatures, it was found that under other conditions, the reaction temperature range of 400- 500 ℃, especially when the reaction temperature is 450 ℃, the aldimine condensation reaction has little effect on the solid-phase properties of the catalyst. The specific surface area (221.95m2 / g) and pore volume (0.2491cm3 / g) The pore size (4.49nm), lower carbon deposition (11.92%) and higher alkylpyridine yield (70.94%).
