A process for catalytic cracking and C3/C4 olefin alkylation with phosphorus stabilized faujasite catalyst is disclosed. Catalytic cracking produces C3 and C4 olefins, which are alkylated using phosphorus stabilized and water activated cracking catalyst. Spent alkylation catalyst may be discharged into the FCC unit.

Alkylation with activated equilibrium FCC catalyst

Aqueous sulfur and caustic component-containing waste streams are disposed of in an environmentally acceptable manner employing a process featuring integrated coking and gasification operations.

Process for the disposal of aqueous sulfur and caustic-containing wastes

This invention relates to a method for removing organic directing agents from as-synthesized molecular sieves comprising:

Method to recover organic templates from freshly synthesized molecular

An azeotropic distillation method for separating diamondoids from a near-boiling solvent. The method is particularly useful for recovering diamondoids extracted from a produced natural gas stream via hydrocarbon solvent injection.

Azeotropic distillation process for recovery of diamondoid compounds

A two-stage method is provided for converting diamondoid-containing wash oils to gasoline comprising a first hydrocracking stage and a second reforming stage. In the most preferred embodiment, process conditions are controlled to effect a substantially hydrogen-balanced conversion of diamondoid-containing solvent to a motor gasoline blending component.

Hydrogen-balanced conversion of diamondoid-containing wash oils to

Polymeric compositions of matter and methods of making the same are disclosed, said polymeric compositions comprising at least one monomer having the structure of one selected from the group consisting of diamantane, triamantane and the higher adamantalogs, said monomer being bonded through at least one double bond extending through a methylene position of said monomer.

Diamondoid polymeric compositions

Diamondoid compounds are concentrated in a solvent mixture containing at least 20% by weight of normal and slightly branched C.sub.5 -C.sub.30 paraffins by selectively converting the paraffins to lower boiling aliphatic hydrocarbons and separating the lower boiling aliphatics from the solvent mixture to yield a concentrated solvent mixture enriched in diamondoid compounds. Useful shape selective catalysts include zeolites having Constraint Indices from about 1 to about 12, such as ZSM-5 and MCM-22.
