OCR catalyst online replacement) is Chevron’s industrialization technology, and its industrial application broadens the range of raw materials for RDS / VRDS hydroprocessing. Cbevron has introduced a catalyst specifically for residue reforming. ISOCRACKINGI Art was developed by Chevron Corporation in the 1990’s. In the 1960s, the company developed a series of hydrocracking catalysts called “co-polymer” which can be used to produce middle distillates.
