    摘要： Enabling a transalkylation process to handle both C10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column that is also closely integrated with the transalkylation unit. No longer requiring a rigorous split between C9 and C10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. These improvements result in an aromatics complex apparatus with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.

    摘要： Enabling a transalkylation process to handle both C10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column and integrated together with the transalkylation unit to reduce costs. No longer requiring a rigorous split between C9 and C10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. These improvements result in an aromatics complex apparatus with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.

    摘要： Enabling a transalkylation process to handle both C10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column. No longer requiring a rigorous split between C9 and C10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. A further enhancement to the flow scheme is accomplished through the elimination of clay treaters in favor of selective olefin saturation at the exits of a reforming unit and an isomerization unit. These improvements result in an aromatics complex with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.

    摘要： This invention is drawn to a process for isomerizing a non-equilibrium mixture of alkylaromatics in two sequential zones, the first zone operating in the absence of hydrogen using a platinum-free catalyst and the second zone using a catalyst comprising a molecular sieve and a platinum-group metal component to obtain an improved yield of para-xylene from the mixture relative to prior art processes.

    摘要： The use of transalkylation catalysts to react heavy aromatic compounds of carbon number nine (and heavier carbon numbers) with benzene to form carbon number eight aromatics is disclosed. The catalyst system preserves ethyl-group species on the heavier aromatics that are otherwise de-ethylated over most gas-phase transalkylation catalysts to form undesired ethane gas with benzene or toluene. The catalyst system also promotes methyl-group species transalkylation at selected conditions. Thus, by using the transalkylation system, a greater yield of para-xylene or other carbon number eight aromatics may be achieved overall within an integrated aromatics complex.

    摘要： A reforming and isomerization process has been developed. A reforming feedstream is charged to a reforming zone containing a reforming catalyst and operating at reforming conditions to generate a reforming zone effluent. Hydrogen and an isomerization feedstream is charged into an isomerization zone to contact an isomerization catalyst at isomerization conditions to increase the branching of the hydrocarbons. The isomerization catalyst is a solid acid catalyst comprising a support comprising a sulfated oxide or hydroxide of at least an element of Group IVB, a first component being at least one lanthanide series element, mixtures thereof, or yttrium, and a second component being a platinum group metal or mixtures thereof. The reforming zone effluent and the isomerization zone effluent are each separated to form a light ends stream and a product stream. The light ends streams are combined for processing in a net gas re-contacting zone.
