In C5/C6 isomerization, we want to process low benzene (3%) and high C7+ (up to 15mol%). Our plant is designed to handle high benzene (up to 5.5%) and 7% of C7+ in the feed naphtha. We are expecting more severity on reactors and hence more cracking. If any one have experience on this, please share especially on yield and cracking. (what %age of isomerization yield will be lowered? and how much cracking will increase)
