CATALYST FOR HYDROTHERMAL LIQUEFACTION OF PLANT BIOMASS Russian patent published in 2018 - IPC B01J21/04 B01J21/06 B01J23/02 B01J23/14 B01J27/18 C10B53/02 

FIELD: biotechnology; chemistry.

SUBSTANCE: invention relates to catalysts for hydrothermal liquefaction of plant biomass and can be used in the preparation of alternative liquid motor fuels. Catalyst is in fluorinated and/or sulphated form and comprises, wt. %: strontium oxide or titanium oxide or tin oxide, or a mixture thereof 1–50, a finely dispersed alumina-containing oxide carrier comprising phosphates or aluminum arsenates being the rest, up to 100. Technical result is the increased catalyst activity due to its greater specific surface area and the presence of an isomerizing component. High value of the specific surface area of the catalyst leads to an increased content of a gasoline component, and the isomerizing function of the catalyst used under the conditions of the hydrothermal liquefaction reaction leads to the increased octane number of the gasoline fraction contained in the resultant bio oil.

EFFECT: use of the described catalyst provides improved low-temperature properties of the diesel component of the resultant bio-oil, also due to the increased content of the isobaric hydrocarbons in the latter.
