    摘要： In a process for the production of para-xylene, methanol is preheated to a first temperature, an aromatic feedstock comprising toluene and/or benzene is preheated to a second temperature and the preheated methanol and aromatic feedstocks are fed to a reactor at a first methanol to aromatic feedstock molar ratio. The preheated aromatic feedstock is contacted with the preheated methanol under alkylation conditions in the reactor in the presence of a catalyst so that the methanol reacts with the aromatic feedstock to produce an effluent comprising para-xylene. During the reaction, a temperature is measured within the reactor and is compared with a predetermined optimal temperature. The methanol to aromatic feedstock molar ratio is then adjusted in a manner to reduce any difference between the measured and predetermined optimal temperatures in the reactor.

    摘要： In a process for producing a para-xylene enriched product from a gaseous mixture comprising at least para-xylene, meta-xylene and ortho-xylene, the gaseous mixture is contacted with an adsorbent capable of selectively adsorbing para-xylene and comprising a crystalline molecular sieve having an average crystal size between about 0.5 micron and about 20 microns. The contacting is conducted at a temperature and pressure such that at least part of the para-xylene in the mixture is adsorbed by the adsorbent to produce a para-xylene-depleted effluent stream. The para-xylene is then desorbed from said adsorbent and collected to form a para-xylene enriched stream. The adsorption and desorption steps are repeated for a plurality of cycles, such that the time between successive contacting steps is no more than 10 seconds.

    摘要： Catalysts have been discovered that are useful in hydrogenation reactions, and particularly for the selective hydrogenation of acetylene and/or methyl acetylene (MA) and/or propadiene (PD) in light olefin-rich feedstreams. These catalysts can selectively hydrogenate acetylene with less selectivity to making oligomers (green oil) as compared with existing commercial catalysts, particularly palladium catalysts. These catalysts are non-palladium catalysts, and have three different constituents that are metal or metal-based components. The metal of the first constituent may be nickel or platinum, the metal of the second constituent may be from Groups 1–10, and the metal of the third constituent may be from Groups 11–12, where the Groups are of the Periodic Table of Elements (new IUPAC notation).

    摘要： It has been discovered that a dual bed process using two different catalysts for the selective hydrogenation of acetylene and/or methyl acetylene (MA) and/or propadiene (PD) in a light olefin-rich feedstream can be accomplished with less selectivity to making oligomers (green oil) as compared with existing commercial technologies, if a low oligomers selectivity catalyst is used first in the process. A palladium catalyst may be used as a second, sequential catalyst to further hydrogenate acetylene and/or MAPD while consuming at least a portion of the balance of the hydrogen present. The first catalyst should be different from the second catalyst.
