    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： This invention relates to an improved hydrotreating process for removing sulfur from naphtha and distillate feedstreams. This improved process utilizes a hydrotreating zone, an acid gas removal zone, and a pressure swing adsorption zone having a total cycle time of less than about 30 seconds for increasing the concentration of hydrogen utilized in the process.
