Abstract
A hydrotreating catalyst is prepared from coal mineral matter obtained by low temperature ashing coals of relatively low bassanite content by the steps of: (a) depositing on the low temperature ash 0.25-3 grams of an iron or nickel salt in water per gram of ash and drying a resulting slurry; (b) crushing and sizing a resulting solid; and (c) heating the thus-sized solid powder in hydrogen.
Claims7
A process for preparing a hydrotreating catalyst from mineral matter of low-temperature ash from coal of relatively low bassanite content comprising the steps of
- (a) depositing on the low-temperature ash 0.25-3 grams of an iron or nickel salt in water per gram of mineral matter and drying a resulting slurry,
- (b) crushing and sizing a resulting solid, and,
- (c) heating the thus-sized solid powder in hydrogen at a temperature in the range of 573-873 K. for a duration up to 200 hours.
