    摘要: A process for converting ethylene to liquid fuel products utilizing a ZSM-5 catalyst that is essentially free of catalyst metals other than silica and alumina, where the catalyst has been subjected to a post-synthesis treatment comprising contacting the catalyst with a solution comprising at least one of an acid or a base to increase the resistance of the catalyst to accumulation of coke in the zeolite crystallite and extend catalyst life. The base treatment is provided by a weak sodium hydroxide of less than 1 Molar. The acid treatment comprises a hydrogen chloride solution exceeding 2 Molar.

    摘要: The present disclosure relates to processes for formation of a molecular sieve, particularly a metal- promoted molecular sieve, and more particularly an Iron(III) exchanged zeolite. Preferably, the zeolite is of the chabazite form or similar structure. The processes can include combining a zeolite with Iron(III) cations in an aqueous medium. The process can be carried out at a pH of less than about 7, and a buffering material can be used with the aqueous medium. The processes beneficially result in Iron exchange that can approach 100% along with removal of cations (such as sodium, NH4, and H) from the zeolite. An Iron(III)-exchanged zeolite prepared according to the disclosed processes can include about 2,000 ppm or less of cation and about 1% by weight or greater of Iron(III). The disclosure also provides catalysts (e.g., SCR catalysts) and exhaust treatment systems including the Iron(III)-exchanged zeolite.
