METHOD FOR MAKING AVIATION KEROSENE Russian patent published in 2009 - IPC C10G65/04 

FIELD: chemistry.

SUBSTANCE: method is enabled by kerosene cut hydrotreating at higher temperature and pressure with catalyst added. Invention concerns the method implying that raw stock is pre-passed through the inert "filter" bed in ratio of inert bed and catalyst within 2-98 vol. % to 25-75 vol. %. Prepared hydrogenation product is mixed with initial raw stock in ratio 60-40 wt % to 95-5 wt %.

EFFECT: prepared hydrogenation product is characterised by practically total absence of mercaptans (~0,001 wt %) and minimal content of the other sulphide compounds.
