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： The invention is to a process for removing contaminants from a compressor and/or compressor intercooler in a methanol to olefin separation system. The process comprises compressing an effluent in a compressor having an inlet and an outlet and a compressor surface, the compressing occurring under conditions effective to form a contaminant on the compressor surface. A contaminant-removal medium is injected into the compressor or intercooler and the contaminant-removal medium contacts the contaminant under conditions effective to remove the contaminant from the compressor or intercooler inner surface thereby forming a mobile contaminant. The mobile contaminant is then removed from the compressor or intercooler.

摘要： This invention comprises a method of producing ethylene rich product streams from a pressurized charge gas mixture of olefins and other components received from olefin generation/preparation processes. The method of this invention may eliminate the need for cryogenic fractional distillation and other special separation equipment operating at temperatures below -55.degree. F., and thus also potentially eliminate the refrigeration and heat exchange equipment needed to achieve those low temperatures. Alternatively, the method of this invention may eliminate the need for a circulating lean oil absorbant material, and thus also potentially eliminate the heat exchange equipment and reduces the refrigeration and fractional distillation load required to manage that material. In accordance with the process of this invention, a secondary ethylene rich product stream is produced at a rate and composition suitable for subsequent generation of a primary ethylene rich product potentially containing substantially no components having a boiling point at least as low as ethylene. Further, the secondary ethylene rich product stream may be suitable as feedstock in the production of ethylene derivatives, or be amenable to further concentration of ethylene using bulk separation techniques, or combinations thereof. Accordingly, the capital and operating cost associated with the manufacture of ethylene rich product streams from pressurized charge gas mixtures made by olefin generation processes may be significantly reduced through the method of this invention.
