摘要： In a method of synthesizing a silicoaluminophosphate molecular sieve having 90%+CHA framework type character, a reaction mixture is prepared comprising first combining a reactive source of aluminum with a reactive source of phosphorus to form a primary mixture that is aged. A reactive source of silicon and a template for directing the formation of the molecular sieve can then be added to form a synthesis mixture. Crystallization is then induced in the synthesis mixture. Advantageously, (i) the source of silicon comprises an organosilicate, (ii) the source of phosphorus optionally comprises an organophosphate, and (iii) the crystallized silicoaluminophosphate molecular sieve has a crystal size distribution such that its average crystal size is not greater than 5 μm. The molecular sieve can then preferably be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

摘要： This invention is directed to a method of rejuvenating a molecular sieve that has decreased catalytic activity as a result of contact with moisture, and a method of using the rejuvenated catalyst to make an olefin product from methanol feed. The molecular sieve can be rejuvenated by heating at a rate sufficient to increase the catalytic activity of the molecular sieve. The molecular sieve is considered to be rejuvenated when the molecular sieve has a CMCPS that is increased by at least 5% relative to that at a heat rate basis of 40° C./min over a temperature range of from 25° C. to 475° C.

摘要： A method of making a higher olefin product from a C4+ fraction separated from the hydrocarbon product produced by an oxygenate to olefin reaction unit. The C4+ fraction primarily contains butenes which may be directed to a higher olefin reaction unit without removing isobutenes, butanes, and/or butadiene. The C4+ fraction is particularly well suited for the production of higher olefins because of its high olefin content, low branching number, and low contaminent levels. The invention is also directed to an olefin product composition that is produced by contacting the C4+ fraction with an oligomerization catalyst. The olefin composition is characterized by a relatively high octene content, and octene with a branching number less than 1.4.
