WhatsApp: +86 18838072829Axens's HCoal process is also a twostage process (two catalytic reactors). Generally, the ICL process produces highcetane diesel and lowoctane naptha; the DCL process produces onspec diesel and highoctane naptha. (Headwaters points out the hybrid DCL/ICL process can produce premium gasoline and diesel fuel with minimal refining.)
