Methods and systems for transferring feed materials between zones having substantially different pressures, where the transfer can be continuous or semi-continuous. The methods and systems include a plurality of lock hoppers to receive feed material from a low pressure zone and pressurize it with fluid to a pressure of a high pressure zone. The pressurized material can be discharged to a circulation loop, which carries the pressurized material to one or more receiving unit(s) of a pressurized system. At least some feed material remains in the receiving unit(s) and at least a portion of the fluid exits to become part of the circulation loop. After discharge, the lock hoppers can be depressurized so the next pressurization cycle can begin with additional feed material. The lock hoppers can be operated in a time-staggered manner to provide continuous or semi-continuous transfer of material.

A process for the production of a higher hydrocarbon useful as gasoline component from solid biomass is provided. The process provides for longer ZSM-5 condensation catalyst life by contacting the stable oxygenated hydrocarbon intermediate containing diols produced from digestion and hydrodoxygenation of the solid biomass to an amorphous silica alumina catalyst to reduce the diols content, and optionally removing water, prior to contacting with the ZSM-5 condensation catalyst.

Biomass conversion process to hydrocarbons

An improved process for the production of a higher hydrocarbon from solid biomass is provided. Solid biomass that has been digested and hydrodeoxygenated in a liquid digestive solvent in the presence of a hydrothermal hydrocatalytic catalyst is separated to an organic rich phase and an aqueous rich phase containing diols. At least a portion of the aqueous rich phase is contacted with an acidic amorphous silica alumina catalyst producing monooxygenate-containing stream comprising water, organic monooxygenates, and unsaturated aliphatic hydrocarbons. At least a portion of the monooxygenate-containing stream is contacted with a solid acid condensation catalyst to produce a higher hydrocarbons stream. At least a portion of the organic rich phase is also contacted with a solid acid condensation catalyst to produce a higher hydrocarbons stream.

A process for the production of a higher hydrocarbon useful to produce diesel components from solid biomass is provided. The process provides for improved production of diesel components by contacting the stable oxygenated hydrocarbon intermediate containing diols produced from digestion and hydrodoxygenation of the solid biomass to an amorphous silica alumina catalyst to reduce the diols content, and removing water prior to contacting with the condensation catalyst to produce the higher hydrocarbon.

Systems and methods involving hydrocatalytic reactions that use molecular hydrogen obtained from a biogas generated from at least a portion of the hydrocatalytic reaction product. Hydrocatalytic reactions can require significant quantities of molecular hydrogen, particularly if the molecular hydrogen is being introduced under dynamic flow conditions. The present disclosure provides systems and methods that can allow for reducing the carbon footprint of the fuels formed from the hydrocatalytic reaction because at least a portion of the hydrogen used in the hydrocatalytic reaction has low carbon footprint. A fuel with low carbon footprint can qualify for certain governmental status that provides certain benefits.

A method of extending the catalyst life of a hydrogenolysis catalyst activity in the presence of biomass and aqueous solution is described. Lignocellulosic biomass solids and aqueous solution is provided to in a hydrothermal digestion unit in the presence of a digestive solvent, and a supported hydrogenolysis catalyst containing (a) sulfur, (b) Mo or W, and (c) Co, Ni or mixture thereof, incorporated into a solid metal oxide support. The lignocellulosic biomass solids in the hydrothermal digestion unit is heated to a temperature in the range of 180&#xb0; C. to less than 300&#xb0; C. in the presence of digestive solvent, hydrogen, and in the range of 0.15 wt. % to 12.5 wt. %, based on catalyst, of HS or HS source at least partially soluble in aqueous solution, and the supported hydrogenolysis catalyst forming a product solution containing plurality of oxygenated hydrocarbons, the hydrothermal digestion unit maintaining protective sulfur concentration.

Processing of a reaction product mixture containing at least one volatile organic compound as well as lignin, lignin derived compounds, and/or unextracted cellulose and hemicellulose using a recovery system comprising at least two flashers or at least one flasher and at least two reboilers. In a particular embodiment, the reaction product mixture comes from reactions involving deconstruction (or digestion) of biomass, particularly cellulosic biomass which contains various polysaccharides (e.g., carbohydrates) and lignin.

Digestion of cellulosic biomass solids may be complicated by release of lignin therefrom. Methods and systems for processing a reaction product containing lignin-derived products, such as phenolics, can comprise hydrotreating the reaction product to convert the lignin-derived products to desired higher molecular weight compounds. The methods and systems can further include separating the higher molecular weight compounds from unconverted products, such as unconverted phenolics, and recycling the unconverted phenolics for use as at least a portion of the digestion solvent and for further conversion to desired higher molecular weight compounds with additional hydrotreatment. The methods and systems can further include a further hydrotreatment step configured for additional lignin conversion and/or a further hydrotreatment step configured for generating hydrogen.
