摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction additive comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve. The molecular sieve is normally a large pore size zeolite such as USY or zeolite beta or an intermediate pore size zeolite such as ZSM-5. The metal is normally a metal of Period 3 of the Periodic Table, preferably zinc or vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

摘要： EMM-3 (ExxonMobil Material number 3) is a new crystalline microporous material with a framework of tetrahedral atoms connected by atoms capable of bridging the tetrahedral atoms, the tetrahedral atom framework being defined by the interconnections between the tetrahedrally coordinated atoms in its framework. EMM-3 can be prepared in aluminophosphate (AlPO) and metalloaluminophosphate (MeAPO) compositions with the hexamethonium template. It has a unique X-ray diffraction pattern, which identifies it as a new material. EMM-3 is stable to calcination in air, absorbs hydrocarbons, and is catalytically active for hydrocarbon conversion.

摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction catalyst composition comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve as well as a cerium component which enhances the stability and sulfur reduction activity of the catalyst. The molecular sieve is normally a faujasite such as USY. The primary sulfur reduction component is normally a metal of Period 3 of the Periodic Table, preferably vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

摘要： A feedstock of low molecular weight oxygenates such as methanol and/or dimethylether is contacted with a mildly presteamed or hydro-thermally treated zeolite catalyst in a reaction zone to produce liquid hydrocarbons in the gasoline boiling range. The pretreated zeolite catalyst has an .alpha.-value (acid cracking activity) substantially the same as the .alpha.-value of fresh unsteamed catalyst and shows increased stability and resistance to aging under oxygenate conversion conditions of elevated temperature and pressure.

摘要： A process for removing catalyst fines from the wax product produced in a slurry Fischer-Tropsch reactor comprises removing the wax product from the reactor and separating the catalyst fines by passing the wax product through a high gradient magnetic field, whereby the catalyst fines are held by a magnetized filter element and the wax product passes through unhindered to form a purified wax product which is ready for upgrading. The separated catalyst fines are returned to the reactor by backwashing the filter element.
