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:
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:
A process for converting biomass to hydrocarbons and oxygenates that 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:
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:
Disclosed are solid titanium-free Fischer-Tropsch catalysts including iron homogeneously modified with a zirconium promoter/stabilizer. The homogeneously mixed solid catalysts can be formed through co-precipitation of iron and zirconium precursors followed by calcination and reduction to form the active catalyst materials. The catalysts can optionally include additional materials such as copper, potassium, and silicon promoters.
