Abstract: Methods are provided for performing fluid catalytic cracking (and/or other hydrothermal processing for cracking of hydrocarbons) on a feedstock containing hydrocarbons in the presence of a catalyst that includes zeolite Beta that is stabilized toward hydrothermal conditions. The hydrothermally stabilized zeolite Beta (including any of the various polymorphs) corresponds to zeolite Beta that is formed without the use of an organic structure directing agent, and that is further stabilized by addition of one or more stabilizers, such as lanthanide series elements or phosphorus.

Abstract: This disclosure relates to the preparation of diphenyl compounds, especially dimethylbiphenyl compounds, in which there is one methyl group on each ring, and their oxidized analogues. These compounds, and particularly alkylated biphenyl compounds and biphenylcarboxylic acids, alcohols and esters, are useful intermediates in the production of a variety of commercially valuable products, including polyesters and plasticizers for PVC and other polymer compositions.

Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more large pore zeolitic catalysts, which may be prepared from a precursor zeolite. In some examples, a large pore zeolitic catalyst may be utilized to selectively reduce the endpoint of a hydrocarbon composition.

Abstract: In a process for separating one or more 3,3′-, 3,4′- and 4,4′-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with an adsorbent containing a zeolite having a largest diffuse along dimension of at least 4 Angstroms. The adsorbents provide selective adsorption of 4,4′-dimethyl biphenyl.

Abstract: A composition can include a Rho zeolite with a RHO topology having a Si to B ratio or a Si to A1 ratio greater than or equal to 8. Making such a composition can include heating an aqueous reaction mixture having a molar ratio of atomic Si to atomic B of about 4 to about 50 or a molar ratio of atomic Si to atomic Al of about 4 to about 50 in the presence of a C4-C6 diquat of N,2-dimethylbenzimidazole structure directing agent to a temperature of at least 75° C. to produce a Rho zeolite.

Abstract: Zeolitic and molecular organic framework materials as catalysts suitable for generating branched olefins from linear olefins, thereby increasing the octane of a composition comprising the linear olefins. In particular, catalyst may exhibit selectivity for methyl-shift isomerization over cracking, alkylation, and oligomerization.
