To satisfy these requirements and to respect more stringent regulations, the petroleum industry has to face the challenge of upgrading the heavier cuts into valuable products like diesel. Purposely, conversion processes, such as hydrocracking (HCK), will require a continuous improvement of the catalytic materials, such as amorphous silica alumina (ASA) supported NiW sulfides catalysts, widely used in HCK process for purification purpose. 收起
