Hydrotreating and Hydrofinishing
HDMax® 510 is a hydrotreating catalyst, developed primarily for severe hydrotreating operation of waxes and lube oil stocks. Its macroporous structure is best suited to improving color and oxygen stability as well as lowering the organic acidity of the product. HDMax® 510 is a robust nickel oxide / molybdenum oxide catalyst. It is available in the CDS shape.
HDMax® 520 is best suited to hydrofinishing reactions aimed at removing chemically active compounds which affect color and color stability. Due to its specific macroporous structure and acidic properties, the HDMax® 520 hydrofinishing catalyst produces water clear white oils.
