    摘要： The invention relates to a process for converting an oxygenate feedstock into an olefin product stream comprising (a) contacting an oxygenate feedstock with a molecular sieve catalyst in a reactor under conditions effective to convert the feedstock into an olefin product stream and to form carbonaceous deposits on the catalyst; (b) contacting at least a portion of the catalyst having said carbonaceous deposits with an oxygen containing gas under conditions effective to obtain a regenerated catalyst having a reduced carbonaceous deposit level and having an increased molecular oxygen content; (c) removing at least 60% by volume of said molecular oxygen from the regenerated catalyst based upon the total volume of molecular oxygen; (d) returning said regenerated catalyst to said reactor; and (e) repeating steps (a)–(d).

    摘要： This invention provides a methanol composition, a method of making the composition, and a method of using the composition. The methanol composition of this invention is supplemented with certain additional alcohols and/or aldehydes, and serves as a particularly desirable feed stream for use in the manufacture of olefins such as ethylene and propylene. Such feed streams result in increased production of ethylene or in the increased production of both ethylene and propylene.

    摘要： Disclosed herein is a method of recovery of the activity of a molecular sieve catalyst following use of the catalyst in an OTO conversion process. This is achieved by a regeneration apparatus and a method of regenerating a molecular sieve catalyst, comprising two stages. In a pretreatment stage, the catalyst is pretreated under pretreatment conditions by heating the catalyst to a temperature of between 320° C. to 700° C. in an oxygen depleted medium for a residence time of between 1 minute to two hours; and, in a regeneration stage, the catalyst is regenerated under regeneration conditions by heating the catalyst at a temperature of between 200° C. to 700° C. in an oxidizing medium for a residence time of between 1 to 60 minutes.
