DESULFURISATION AND NEW METHODS OF DESULFURISATION Russian patent published in 2008 - IPC B01J20/30 C10G25/00 C10G25/12 

FIELD: chemistry, technological processes.

SUBSTANCE: composition for hydrocarbon raw material desulfurisation contains metal oxide and activator, in which part of activator is present in form of activator with reduced valency. Method of obtaining composition includes mixing of liquid, zinc-containing compound, material containing silicon oxide, aluminium oxide, drying, burning of dried mixture, introduction of activator, bringing activated mixture into contact with acid, selected from group, including citric acid, tartaric acid and their combinations, with obtaining mixture that has contacted, drying and burning, reduction of burned mixture by means of reducing agent with obtaining of composition, which contains activator with reduced valency, and isolation of said composition.

EFFECT: composition is efficient for application in desulfurisation zone for removal of sulfur from hydrocarbon flow, obtaining desulfurised cracking-benzene or Diesel fuel.
