A carbon monoxide combustion catalyst and a method of making the catalyst used in fluid bed catalytic cracking process. The catalyst can contain metals and other composites which promote oxidation of carbon monoxide to carbon dioxide during regeneration of spent FCC catalyst.

Carbon monoxide combustion catalyst and a process of preparation thereof

The present invention relates to a process for obtaining food grade hexane, comprising: fractionating a hydrocarbon feed having a boiling point in the range of 50&#xb0; C. to 140&#xb0; C. to obtain a hydrocarbon fraction having boiling point in the range of 63&#xb0; C. to 69&#xb0; C. and having 3%-15% (wt/wt) of aromatic compounds content; extracting the hydrocarbon fraction by counter current solvent extraction using sulfolane as a solvent to obtain a first raffinate phase; extracting the first raffinate phase by co-current solvent extraction using sulfolane as a solvent to obtain a second raffinate phase; and washing the second raffinate phase with water to obtain a food grade hexane containing less than 100 ppm of aromatic compounds.

Process for obtaining food grade hexane

The present invention relates to sulphur reduction catalyst additive composition comprising an inorganic porous support incorporated with metals; an alumino silicate or zeolite component; an alumina component and clay. More particularly the present invention relates to sulphur reduction catalyst additive composition comprising refinery spent catalyst as support. The primary sulphur reduction catalyst additive component of the catalyst composition contains metals of Period III or IV of the Periodic Table, preferably Zinc or Magnesium or combination thereof or one of the transition metals along with other metals.
