New methods upgrade refinery residuals into lighter products

摘要

Gasification of refinery residue is a method to produce hydrogen, carbon monoxide (CO) or both for chemicals (ammonia, methanol and oxo-alcohols). Recently, gasification is also being used to close the hydrogen gap for refineries. This operation is often coupled with further upgrading of refinery bottoms from other unit processes such as solvent deasphalting, coking and visbreaking.
