    摘要： In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.

    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.

    摘要： This invention provides methods of making molecular sieve catalyst particles, molecular sieve slurries that can be used in such methods, molecular sieve catalyst compositions and their use in catalytic hydrocarbon conversion processes. In one of its aspects, the invention provides a method of making molecular sieve catalyst particles, the method comprising the steps of: a) providing a solution or suspension of an aluminum-containing inorganic oxide precursor in a liquid medium; b) combining the solution or suspension of aluminum-containing inorganic oxide precursor with a molecular sieve, and optionally other formulating agents, to form a catalyst formulation slurry; c) aging the catalyst formulation slurry to generate in said slurry a percentage, or increase in said slurry the existing percentage, of aluminum atoms of the aluminum-containing precursor in the form of oligomers having a sharp 27 Al NMR peak at 62-63 ppm; and d) forming molecular sieve catalyst particles from the catalyst formulation slurry. The catalyst compositions obtained by the methods of the present invention have improved attrition resistance, and are particularly useful in hydrocarbon conversion processes.
