PROCESS FOR PRODUCING CRUDE BIO-OIL FROM BIOMASS WITH A HIGH MOISTURE CONTENT AND CATALYST FOR HYDROTHERMAL LIQUEFACTION OF STREAMS OF BIOMASS WITH A HIGH MOISTURE CONTENT
The present invention addresses to a hydrothermal liquefaction process capable of generating a liquid stream, rich in renewable molecules, with lower oxygen content, lower percentage of water and lower acidity compared to other products of thermochemical processes of biomass conversion. In order to effectively carry out this process, a catalyst was developed, obtained from the calcination of castor bean hull, to be used in the field of biofuels in order to provide an environmentally friendly alternative for the production of fuels.
INTEGRATED CONVERSION AND OLIGOMERIZATION OF BIO-DERIVED ALCOHOLS
Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM-48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.
SELECTIVE PRODUCTION OF LIGHT SYNTHETIC GASOLINE
A production plant and a method for production of a synthetized gasoline product from a synthetic hydrocarbon mixture produced from a mixture of reactive oxygenates, the method including a. separating the synthetic hydrocarbon mixture in at least a light hydrocarbon fraction, and a higher boiling hydrocarbon fraction, wherein the higher boiling fraction comprises at least 70% of the molecules including 10 or more carbon atoms and less than 20% of the molecules comprising exactly 9 carbon atoms, b. directing at least an amount of said higher boiling hydrocarbon fraction as a hydrocracking feedstock to contact a material catalytically active in hydrocracking under effective hydrocracking conditions providing a hydrocracked hydrocarbon stream, wherein at least an amount of said hydrocracked hydrocarbon stream is combined with at least an amount of said light hydrocarbon fraction, to provide said synthetized gasoline product having a T.sub.90 being below T.sub.90 of said synthetic hydrocarbon mixture.
OCTANE ENHANCED INTERMEDIATE HYDROCARBON COMPOSITION

The intermediate hydrocarbon composition includes a renewable first gasoline component in an amount of from 5 to 50%-vol of the total intermediate hydrocarbon composition volume and the rest consisting of a second gasoline component, wherein the second hydrocarbon gasoline component includes unsaturated hydrocarbons from 50 to 90%-vol of the second gasoline component volume.
DISTILLATION SYSTEM AND METHOD USING MICROWAVE-ASSISTED PYROLYSIS
A method of producing a hydrocarbon fuel from a soapstock includes supplying a pyrolysis reactor that includes a microwave absorbent bed susceptible to microwave irradiation, applying microwave energy to the pyrolysis reactor, wherein the microwave absorbent bed converts the microwave energy to thermal energy, supplying the soapstock to the microwave absorbent bed, and condensing a vapor generated by pyrolysis of the soapstock sufficient to collect the hydrocarbon fuel.
PROCESS
A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.
Production of aromatics by pyrolysis, water gas shift and aromatization of CO2
Device and process for converting a feedstock of aromatic compounds, in which the feedstock is notably treated using a fractionation train (4-7), a xylenes separating unit (10) and an isomerization unit (11), and in which a pyrolysis unit (13) treats a second hydrocarbon-based feedstock, produces a pyrolysis effluent feeding the feedstock, and produces a pyrolysis gas comprising CO, CO2 and H2; a WGS water gas shift reaction section (50) suitable for treating the pyrolysis gas and for producing a WGS gas enriched in CO2 and in hydrogen; a CO2 aromatization reaction section (52) suitable for: at least partly treating the WGS gas to produce a hydrocarbon effluent comprising aromatic compounds, and feeding the feedstock with the hydrocarbon effluent.

Cost efficient integration of hydrothermal liquefaction and wet oxidation wastewater treatment.
Aqueous wastewater from hydrothermal liquefaction (HTL) systems is typically high in chemical oxygen demand (COD), which renders classic aerobic wastewater treatment to be prohibitively expensive. HTL wastewater can be processed using thermochemical wet oxidation in a manner that is not only cost efficient but also contributes more heat than is required for the energetically demanding HTL process. Provided are methods and devices for integrated hydrothermal liquefaction of biomass and treatment of resulting wastewater.
