A device and process for the conversion of aromatic compounds, includes/uses: a unit for the separation of the xylenes suitable for treating a cut comprising xylenes and ethylbenzene and producing an extract comprising para-xylene and a raffinate; an isomerization unit suitable for treating the raffinate and producing an isomerate enriched in para-xylene which is sent to a fractionation train; a pyrolysis unit suitable for treating biomass, producing a pyrolysis effluent feeding, at least partially, the feedstock, and producing a pyrolysis gas comprising CO and H.sub.2; a Fischer-Tropsch synthesis reaction section suitable for treating, at least in part, the pyrolysis gas, producing a synthesis effluent sent, at least in part, to the pyrolysis unit.

A method of demulsifying an emulsion with an ionic liquid having a nitrogen or phosphorus cation.

Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

A system and method for torrefying a combination of biomass and biochar colloidal dispersion is provided.

The present invention relates to a process for treating an SRF and/or plastics pyrolysis oil, comprising: a) optionally, selective hydrogenation of the feedstock; b) hydroconversion in an ebullated bed, in an entrained bed and/or in a moving bed, to obtain a hydroconverted effluent; c) separation of the hydroconverted effluent in the presence of an aqueous stream, to obtain a gaseous effluent, an aqueous liquid effluent and a liquid hydrocarbon effluent; d) fractionation of the liquid hydrocarbon effluent to obtain at least one gas stream and a cut with a boiling point of less than or equal to 385° C. and a cut with a boiling point above 385° C.; e) hydrotreatment of said cut comprising compounds with a boiling point of less than or equal to 385° C. to obtain a hydrotreated effluent; f) separation to obtain at least a gaseous effluent and a hydrotreated liquid hydrocarbon effluent.

A method of producing a non-petroleum based electrical insulating oil, wherein the method can include providing a primary mixture of non-petroleum origin, containing isomerized straight chain hydrocarbons; performing a distillation and/or stripping of the primary mixture; collecting a paraffinic base oil as a product of the distillation and/or stripping, containing a mixture of isoalkanes and alkanes; and mixing the base oil with an antioxidant additive.

A process for dewatering a thermochemical oil. The process comprises providing a thermochemical oil comprising water; adding a solvent selected from mesityl oxide, 2-methyltetrahydrofuran, dioxane and furfural to the thermochemical, oil, to form a mixture comprising the thermochemical oil and the solvent; heating the mixture to remove an azeotrope comprising water and the solvent from the mixture, thereby forming a dewatered thermochemical oil. A dewatered thermochemical oil. A fuel precursor.

Systems and methods are provided for co-processing of biomass oil in a fluid catalytic cracking (FCC) system that include recovering an additional source of H.sub.2 or synthesis gas from the overhead product gas stream. The additional H.sub.2 can be used to partially hydrogenate biomass oil prior to co-processing the biomass oil in the fluid catalytic cracking system. Additionally or alternately, the additional synthesis gas can represent an additional yield of products from the process, such as an additional yield that can be used for synthesis of further liquid products.

Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

Systems and methods to provide low carbon intensity (CI) transportation fuels through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and fuel product distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the transportation fuel below a pre-selected threshold that defines an upper limit of CI for the transportation fuel.
