The invention relates to a preparation method for hydrocarbon cuts, said method comprising: a) providing a hydrocarbon feedstock originating from ethanol having an initial boiling point and a final boiling point in the range from 20 to 250 C. and comprising: from 20 to 60% by weight of aromatic compounds; from 20 to 60% by weight of non-cyclic paraffins; and from 2 to 20% by weight of naphthenes, with respect to the total weight of the hydrocarbon feedstock, b) optionally, a step of hydrogenation of the hydrocarbon feedstock originating from ethanol provided during step a) in order to obtain a hydrogenated hydrocarbon feedstock; c) a distillation step (i) of the hydrocarbon feedstock originating from ethanol during step a) or (ii) of the hydrogenated hydrocarbon feedstock according to step b), in order to obtain at least one hydrocarbon cut having a difference of less than 100 C. between the final boiling point thereof and the initial boiling point thereof.

A reactor and its internals used for the thermal processing of a liquid mixture. The reactor comprises plates and at least part of the surface of said plates is used to perform the thermal processing. The reactor and its internals are used for the thermal processing of various liquid mixtures containing organic compounds. The processes, for thermal processing the mixture comprising organic compounds, comprising the steps of feeding the reactor and its internals and being useful for treating wastes oils and/or for destroying hazardous and/or toxic products; and/or for reusing waste products in an environmentally acceptable form and/or way, and/or for cleaning contaminated soils or beaches, and/or cleaning tar pits, and/or use in coal-oil co-processing, and/or recovering oil from oil spills, and/or PCB free transformed oils. A process for fabricating the reactor and its internals is also proposed.

Process for TDAE-1 and TDAE-2 production is initiated with production of DAE Feeds which have kinematic viscosity at 100 C. ranges 24-67 cSt, followed by mixing them with solvent to yield Mixture of DAE Feed with density ranges 0.75-0.85 kg/liter and further contacting the Mixture of DAE Feed with solvent, like furfural, NMP and DMSO to facilitate a counter current liquid-liquid extraction, wherein the TDAE-1 and TDAE-2 are produced at ratio of polar solvent to Mixture of DAE Feed ranges 1.7-2.0 and 0.5-1.7, respectively. The PCA content of TDAE-1 and TDAE-2 are less than 3% weight and 3-20% weight. The amount of 8 Grimmer polyaromatics hydrocarbon content in the TDAE-1 and TDAE-2 are the same, that is, less than 10 mg/kg including Benzo (a) pyrene substance as much as less than 1 mg/kg.

Methods are provided to reduce or minimize fouling within quench systems when quenching effluents containing heavy components, such as heavy hydrocarbons and/or pyrolysis tars/coke. The methods include injecting a low density, low boiling point, high aromatic content fluid into the quench system as a quench solvent. The quench solvent also has a reduced or minimized content of fouling precursors, such as styrene, cyclopentadiene, or dicyclopentadiene.
