摘要:
A process is disclosed for converting lignocellulosic material to liquid fuels. In the process the cellulose is dissolved in an Ionic Liquid. The conversion process may comprise pyrolysis, thermal cracking, hydrocracking, catalytic cracking, hydrotreatment, or a combination thereof. Undissolved lignin is removed from the Ionic Liquid medium, and is converted in a separate conversion process. The Ionic Liquid preferably is an inorganic molten salt hydrate.

The present invention refers to a catalytic process of hydrogenation/hydrogenolysis of glycerol or glycerine into oxygenated compounds and hydrocarbons containing 1 to 3 carbon atoms, using supported metal catalysts based on metals from group VIII-B of the periodic table of the elements, which have been supported by standard techniques on materials having a high specific area, such as powder charcoal, aluminum silicate, alumina, clays, zeolites and molecular sieves.
摘要:
A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8.

摘要:
A hydrocarbon product stream having hydrocarbons with boiling points in the aviation fuel range is produced from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating, deoxygenating, isomerization, and selectively hydrocracking the feedstock to produce paraffinic hydrocarbons having from 9 to 16 carbon atoms and a high iso/normal ratio in a single reaction zone containing a multifunctional catalyst, or set of catalysts, having hydrogenation, deoxygenation, isomerization and selective hydrocracking functions.
