摘要:
This invention relates to a process for production of transportation fuels from biomass. More particularly, this invention relates to a process for using solvent to remove metal impurities and high molecular weight components from biomass derived biocrude to prevent potential catalyst poisoning and catalyst bed plugging in biocrude-to-transportation fuel upgrading process.
摘要:
Oxygenate feedstocks derived from biomass are converted to a variety of fuels including gas, jet, and diesel fuel range hydrocarbons. General methods are provided including hydrolysis, dehydration, hydrogenation, condensation, oligomerization, and/or a polishing hydrotreating.
摘要:
A single pass direct conversion of biomass derived oxygenates to longer chain hydrocarbons is described. The longer chain hydrocarbons include higher naphthene content which is quite useful in the distillate range fuels or more particularly, the jet and diesel range fuels. Naphthenes help the biomass derived hydrocarbons meet product specifications for jet and diesel while really helping cold flow properties.
摘要:
The present invention relates to a process for converting biomass to hydrocarbons and oxygenates. The process may include providing a biomass feedstock and de-oxygenating the biomass feedstock to form a solid-intermediate. The process may further include liquefaction of the solid intermediate, which may be carried out either by rapid heating followed by condensation or by liquefying by applying high pressure. The liquefaction of the solid intermediate may produce a mixture of hydrocarbons and oxygenates, which is generally termed as biocrude. Further, the biocrude is processed by one or more refining means for production of hydrocarbons that can be used as fuel.

摘要:
The present invention relates to a process for converting pyrolysis oil obtained by pyrolysis of biomass into fuel range hydrocarbon by alcoholysis of pyrolysis oil with subsequent hydrotreatment. The current invention provides straightforward methodology to prepare upgradable pyrolysis oil via alcoholysis. The invention uses hydrotreating technology for oxygen removal and hydrocarbon production. The resulting hydrocarbon products are 100% fungible with conventional transportation fuels.
