The correct method for using metal passivators in catalytic cracking is ( B ). A. Add it to the catalyst after dilution B. Add it to the feed oil after dilution C. Spray it directly into the riser after dilution D. Add it to the circulating slurry after dilution
The correct method for using metal passivators in catalytic cracking is ( B ). A. Add it to the catalyst after dilution B. Add it to the feed oil after dilution C. Spray it directly into the riser after dilution D. Add it to the circulating slurry after dilution
The answer is B: it is added to the crude oil after dilution, mainly because the amount added is small, so diesel is generally used for dilution before addition
