ADVANCED ELEVATED FEED DISTRIBUTION APPARATUS AND PROCESS FOR LARGE DIAMETER FCC REACTOR RISERS

摘要

An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions while at the same elevation inside a riser. Multiple distributors may be used to position the tips for injecting feedstock at multiple radial positions. The distributors with tips more deeply positioned in the riser will penetrate a dense catalyst column we discovered generates in risers of larger diameter over 1.3 meters.
