In the reforming unit, under what conditions does the catalyst coking occur? What are the consequences of catalyst coking?
A high content of olefins in the feedstock, high reaction temperatures, low hydrogen-to-oil ratios, and low space velocities can all lead to coking. The consequence is poor reaction efficiency, low octane number and yield, as well as catalyst poisoning
There are many reasons for catalyst coking: for example, leaks in the bottom reboiler of the pre-hydrogenation unit lead to defective refined oil, excessive sulfur content in the feed, too low a hydrogen-to-oil ratio, and a low catalyst circulation rate
