Catalytic reforming process |
摘要 |
A catalyst pretreat procedure wherein a copper, selenium, or sulfur promoted platinum-iridium catalyst, preferably a platinum-iridium-selenium catalyst, is contacted with dry hydrogen at a temperature ranging from about 600 DEG F.-1000 DEG F., at a hydrogen partial pressure ranging from about 1-40 atmospheres at a flow rate sufficient to maintain the moisture level below about 500 parts per million parts by volume of gas in the exit gas stream, for a period of time ranging at least about 16 hours, preferably at least 16 hours to about 200 hours. Treatment of these catalysts at such conditions will provide a selectivity advantage ranging from about 1 to 2 (LV%) higher than a catalyst otherwise similar but not pretreated in this manner.
