摘要:
A process for the production of an isomerate with a RON that is at least equal to 80 and that contains less than 1% by weight of aromatic compounds, starting with a fraction consisting mostly of hydrocarbons with 7 carbon atoms, and containing paraffins, naphthenes, and aromatic compounds in any proportion is described. Said process uses at least one isomerization unit, at least one unit for opening naphthene rings, and at least one separation unit; these units are combined in such a way as to recycle, to exhaustion, methyl cyclohexane, toluene, and normal paraffins and monobranched paraffins.

摘要:
Process for the production of high-purity hydrogen from an ethanol or higher-alcohol feedstock, employing a steam reforming unit, a carbon monoxide conversion unit and a membrane separation unit and comprising intense thermal integration that is obtained by combustion under the control of an effluent of the process so as to provide the calories that are necessary to the steam reforming reaction.
摘要:
Continuous process for the production of prevalently heavy hydrocarbons starting from synthesis gas in the presence of a gas phase, a liquid and a solid catalyst, the above process being carried out using a bubble column, characterized in that the bubble column internally has: (a) at least one draft-tube; (b) at least one device for the inlet of the synthesis gas; (c) at least one device for the inlet of the regenerating gas; (d) at least one device for activating/interrupting the stream of regenerating gas; (e) optional devices suitable for minimizing the mixing of the synthesis gas with the regenerating gas.
摘要:
The invention concerns a process for optimal operation of a slurry bubble column containing a suspension of solid particles in a liquid, characterized in that a gas phase containing the reactant(s) required for the production of the desired products is injected in the form of bubbles close to the lower extremity of said reactor and at least a portion of the liquid fraction and optionally of the solid fraction of said suspension is recirculated, drawn off from close to one extremity of said reactor and reintroduced close to the other extremity of said reactor, with a liquid flow rate U.sub.1 in the reactor which is at least equal to and preferably greater than the sedimentation rate U.sub.s of the solid particles. The invention also concerns an apparatus for optimal operation of the process. Finally, the invention concerns the use of the process and apparatus in the Fischer-Tropsch synthesis.
摘要:
The present invention relates to a method of producing sweet juice from lignocellulosic substrate, wherein enzymatic hydrolysis is carried out by performing cellulase supplementation with supported β-glucosidases used in a reactor separate from the lignocellulose enzymatic hydrolysis reactor.
