Question

The activity of the catalyst in a semi-regenerative catalytic reformer is reduced over time during operation by:

• A. chloride loss
• B. carbonaceous coke
• C. both A and B together
• D. either A or B

Answer 1

The correct option is C both A and B together

In catalytic reforming process, the noble metals platinum and rhenium are the catalysts used on a silica or silica-alumina support base. Fresh catalyst is chlorinated prior to use. On the other hand, an excessive chlorination could depress excessively the activity of the catalyst. Also in the case of the semi-regenerative catalytic reformer, the catalyst is reduced over time by carbonaceous coke deposition and chlorine loss.
