| The main types of platinum based catalysts for propane dehydrogenation are classified into low carbon and high carbon types based on carbon content. The production and experimental data show that the recovery of low carbon propane dehydrogenation catalyst is 98% at 500℃ for 4 hours, acid ratio 1:1.7, and that of high carbon propane dehydrogenation catalyst at 900℃, oxygen flow rate 6~13 L/ min, heat treatment time 6 hours, 6-stage dynamic heat treatment, the direct yield is 90%, which needs to be further improved. |
