    摘要: This invention relates to a FCC process using a mesoporous catalytic cracking catalyst. The mesoporous fluidized catalytic cracking catalyst is selective for minimizing the production of coke and light gas. The catalyst comprises at least one amorphous, porous matrix, each matrix having pores ranging in diameter from about 1 Å to about 10 Å and pores ranging in diameter from about 40 Å to about 500 Å, wherein in the pore range from 50 Å to 250 Å, there is a single maximum in differential pore volume distribution over the 50 Å to 250 Å range.

    摘要: A process for shape-selective hydrocarbon conversion that involves initially contacting a feed stream which includes an alkylaromatic compound and a co-feed of water, under conversion conditions with a catalytic molecular sieve. Preferably, the catalytic molecular sieve has been modified by being ex situ selectivated with a silicon compound. After an effective amount of time, the water co-feed is omitted from the feed stream and the hydrocarbon conversion process is continued. Optionally, the catalytic molecular sieve can also be in situ trim-selectivated.
