摘要: This invention is directed to a molecular sieve having acid catalyst sites and a method of maintaining the acid catalyst sites of a template-containing silicoaluminophosphate molecular sieve. The method comprises providing a template-containing silicoaluminophosphate molecular sieve and heating the molecular sieve in an oxygen depleted environment under conditions effective to maintain or preserve the number of acid catalyst sites. The heated molecular sieve exhibits at least one peak in the infrared region in a range of from 3630 cm−1 to 3580 cm−1. Preferably, the heated molecular sieve exhibits a combined peak area in the 3630 cm−1 to 3580 cm−1 range of at least 10% of a total peak area of all peaks in an infrared region between 4000 cm−1 to 3400 cm−1.

摘要: This invention is directed to a method of making an olefin product from an oxygenate feedstock and a method of protecting catalytic activity of a silicoaluminophosphate molecular sieve. The methods comprise providing a silicoaluminophosphate molecular sieve having catalytic sites within the molecular sieve; shielding the catalytic sites to protect from loss of catalytic activity; and contacting the protected sieve in its activated state with an oxygenate feedstock under conditions effective to produce an olefin product before undesirable loss of catalytic activity. Undesirable loss in catalytic activity occurs when activated molecular sieve contacting the oxygenate feedstock has a methanol uptake index of at least 0.15.

摘要: Disclosed is a method for making olefin product from an oxygenate-containing feedstock. In the method, a silicoaluminophosphate molecular sieve catalyst is contacted with the oxygenate-containing feedstock in a reactor at an average catalyst feedstock exposure index of at least 1.0. The method produces lower coke yield and provides an olefin product which is low in C1-C4 paraffin content. The invention is particularly effective in producing an olefin product having a very low propane content.

摘要: Disclosed is a method of rejuvenating a molecular sieve. The method includes contacting a molecular sieve having a methanol uptake of less than 1, or a catalyst containing molecular sieve having a methanol up of less than 1, with anhydrous liquid or vapor until the methanol uptake ratio is increased by at least 10%. The rejuvenated molecular sieve or catalyst can be used to make an olefin product from an oxygenate-containing feedstock. The preferred molecular sieve is a silicoaluminophosphate (SAPO) molecular sieve.
