Patent number: 9168483Abstract: Methods are provided for forming zeolite crystals suitable for gas phase separations with transport characteristics that are stable over time. The zeolitic materials and/or corresponding methods of synthesis or treatment described herein provide for improved stability in the early stages of process operation for some types of gas phase separations. The methods allow for synthesis of DDR type zeolites that have reduced contents of alkali metal impurities. The synthetic methods for reducing the non-framework alkali metal atom or cation impurity content appear to have little or no impact on the DDR crystal structure and morphology.Type: GrantFiled: November 8, 2013Date of Patent: October 27, 2015Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Peter I.

Patent number: 7683233Abstract: 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.Type: GrantFiled: August 20, 2007Date of Patent: March 23, 2010Assignee: ExxonMobil Chemical Patents Inc.Inventors: John Di-Yi Ou, Sebastian C.
