A family of highly charged crystalline microporous metallophosphate molecular sieves designated PST-16 has been synthesized. These metallophosphates are represented by the empirical formula of:

R.sup.p+.sub.rA.sub.m.sup.+M.sub.xE.sub.yPO.sub.z

where A is an alkali metal such as potassium, R is an organoammonium cation such as ethyltrimethylammonium, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. The PST-16 family of molecular sieves are stabilized by combinations of alkali and organoammonium cations, enabling unique metalloalumino(gallo)phosphate compositions and exhibit the CGS topology. The PST-17 family of molecular sieves has catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

A catalyst composition contains an inorganic porous material with pore diameters of at least 2 nm and of crystals of molecular sieve. The crystals of molecular sieve have an average diameter, measured by scanning electron microscopy, not bigger than 50 nm. The catalyst composition has a concentration of acid sites ranges from 50 to 1200 mol/g measured by TPD NH3 adsorption. An XRD pattern of the catalyst composition is the same as an XRD pattern of the inorganic porous material.

The present disclosure generally relates to methods and systems for reforming and isomerizing hydrocarbons. More particularly, the present disclosure relates to a novel combination of two traditionally separate reforming and isomerization reaction zones. A first hydrocarbon stream comprising C.sub.5-C.sub.6 hydrocarbons is isomerized in a first isomerization zone. A second hydrocarbon stream comprising C.sub.7+ hydrocarbons is reformed thus producing a C.sub.7 hydrocarbon stream and a C.sub.8 hydrocarbon stream. The reformed C.sub.7 stream is then isomerized in a second isomerization zone.

A catalyst system comprising a combination of: 1) one or more catalyst compounds comprising at least one nitrogen linkage; 2) a support comprising an organosilica material, which is a mesoporous organosilica material; and 3) an optional activator. Useful catalysts include pyridyldiamido transition metal complexes, HN5 compounds, and bis(imino)pyridyl complexes. The organosilica material is a polymer of at least one monomer of Formula [Z.sup.1OZ.sup.2SiCH.sub.2].sub.3(1), where Z.sup.1 represents a hydrogen atom, a C.sub.1-C.sub.4alkyl group, or a bond to a silicon atom of another monomer and Z.sup.2 represents a hydroxyl group, a C1-C.sub.4alkoxy group, a C.sub.1-C.sub.6 alkyl group, or an oxygen atom bonded to a silicon atom of another monomer. This invention further relates to processes to polymerize olefins comprising contacting one or more olefins with the above catalyst system.

This invention relates to a hydrogen spillover-based catalyst and use thereof, wherein a hydrogen activation metal cluster is dispersed in the form of being encapsulated in a crystalline or amorphous aluminosilicate matrix which is partially or fully structurally collapsed zeolite, thereby exhibiting high hydroprocessing or dehydrogenation activity and suppressed C-C hydrogenolysis activity.
