| 英文摘要 | a novel two-stage catalyst combination system for co hydrogenation was applied. first, the thermal coupling conditions between modified fisher-tropsch (ft) synthesis catalyst cu25fe22co3k3/sio2 and methanol synthesis catalyst cu/zno/al2o3 were investigated. then, the loading mode and volume of cu/zno/al2o3 and cu25fe22co3k3/sio2 catalyst combination system for lower alcohols synthesis was optimized. the obtained thermal coupling conditions were as follows: (reduction conditions) t = 400 degrees c, p = 0.5 mpa, and gshv = 840 h(-1); (reaction conditions) t = 280 degrees c, p = 5.5 mpa, and gshv = 2800 h(-1). under these conditions, the per-pass conversion of co and yield of lower alcohols reached 48.3% and 492.0 g kg(-1) h(-1), respectively, over the two-stage bed catalyst combination system of cu25fe22co3k3/sio2 (2.5 ml)//cu/zno/al2o3 (2.5 ml). it was indicated that the combined loading mode in a two-stage bed reactor showed better catalytic performances than single or mixed loading mode in a single bed reactor. through a lumped kinetics study over the cu25fe22co3k3/sio2 (2.5 ml)// cu/zno/al2o3 (2.5 ml) two-stage bed catalyst combination system, this can be due to the improvement of methanol synthesis over the lower cu/zno/al2o3 catalyst which was promoted by the generated co2 from the upper cu25fe22co3k3/sio2 catalyst. |
