The invention relates to the use of particulate silicone resins in the absence of added organic solvents with particulate inorganic materials to form structured bodies and in particular molecular sieve containing structured bodies. The silicone resin is used in the form of a particulate with an average particle size of less than 700 um. Upon calcining, the silicone resin is converted to silica which acts as a binder.

Structured bodies with siliceous binder

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.

Gasoline sulfur reduction in fluid catalytic cracking

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-. 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.

In a process for preparing a selectivated catalyst composition useful in the disproportionation of toluene, a catalyst comprising an acidic molecular sieve is contacted with a boron compound at a temperature in excess of 500&#xb0; C.; and the resultant catalyst is then contacted with a medium containing hydrogen ions to at least partially restore the acid activity of the molecular sieve.

Selectivation of molecular sieve catalysts and use therof in hydrocarbon conversion

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.

EMM-3, new crystalline microporous material

A method is disclosed for modifying a catalytic molecular sieve for shape-selective hydrocarbon conversions comprises:

High temperature calcination of selectivated molecular sieve catalysts for activity and diffusional modification

A process for catalytic cracking of a hydrocarbon feedstock feeds to produce an enhanced yield butylenes and isobutane comprises contacting the feedstock with a catalyst composition comprising MCM-68. The MCM-68 may be used as the primary cracking catalyst or may be used as an additive component in conjunction with a conventional cracking catalyst, such as a large pore molecular sieve having a pore size greater than 7 Angstrom.

Catalytic cracking processing using an MCM-68 catalyst

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 4 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.

A process for catalytic cracking of a hydrocarbon feedstock comprises contacting the feedstock with a catalyst composition comprising a primary cracking component, such as zeolite Y, and a mesoporous aluminophosphate material which includes a solid aluminophosphate composition modified with at least one element selected from zirconium, cerium, lanthanum, manganese, cobalt, zinc, and vanadium. The mesoporous aluminophosphate material has a specific surface area of at least 100 m /g, an average pore size less than or equal to 100 &angst;, and a pore size distribution such that at least 50% of the pores have a pore diameter less than 100 &angst;.

A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is useful as an acid catalyst and as an adsorbent.
