    摘要： A process for converting methanol to light olefins is disclosed and claimed. The catalyst is a metalloaluminophosphate molecular sieve having the empirical formula (ExAlyPz)O2 where EL is a metal such as silicon or magnesium and “x”, “y” and “z” are the mole fractions of EL, Al and P respectively and specifically where “x” has a value of about 0.02 to about 0.08. A preferred molecular sieve is one which has predominantly a plate crystal morphology in which the average smallest crystal dimension is at least 0.1 microns and has an aspect ratio of no greater than 5. The process provides greater selectivity to ethylene and propylene versus C4+ byproducts.

    摘要： A process is disclosed for enhancing the production of light olefins with a catalytic reaction zone containing small pore zeolitic and non-zeolitic catalysts which can significantly improve the yield of ethylene and propylene in a process for the conversion of light olefins having four carbon atoms per molecule and heavier. Specifically, a C.sub.4 olefin stream from an ethylene production complex is converted in a reaction zone over a non-zeolitic catalyst at effective conditions to produce a product mixture containing ethylene and propylene. Ethylene and propylene are separated from the product mixture and recovered. A portion of the remaining heavy hydrocarbons and paraffins may be recycled to the reaction zone for further conversion, or oligomerized to produce valuable downstream products. The additional step of removing iso-olefins from the recycle stream provided significant advantages. The process of the present invention may be applied in commercial ethylene plants, in petroleum refining catalytic cracking operations, and in processes for the conversion of oxygenates such as methanol-to-olefins to enhance the production of ethylene and propylene.

    摘要： The present invention relates to a process for the production of light olefins comprising olefins having from 2 to 4 carbon atoms per molecule from an oxygenate feedstock. The process comprises passing the oxygenate feedstock to an oxygenate conversion zone containing a metal alumninophosphate catalyst to produce a light olefin stream. The light olefin stream is fractionated and a portion of the products are metathesized to enhance the yield of the ethylene, propylene, and/or butylene products. Propylene can be metathesized to produce more ethylene, or a combination of ethylene and butene can be metathesized to produce more propylene. This combination of light olefin production and metathesis, or disproportionation provides flexibility to overcome the equilibrium limitations of the metal aluminophosphate catalyst in the oxygenate conversion zone. In addition, the invention provides the advantage of extended catalyst life and greater catalyst stability in the oxygenate conversion zone.

    摘要： Hydrothermal treatment of silicoaluminophosphate molecular sieves at temperatures in excess of about 700.degree. C. for periods sufficient to destroy a large proportion of their acid sites while retaining at least 80 percent of their crystallinity is found to result in a catalyst for converting methanol to lower olefins having increased catalyst life, increased selectivity for C.sub.2 -C.sub.3 olefins and decreased selectivity for paraffin production than the untreated SAPO-n starting composition.
