摘要:
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.

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.
摘要:
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.
摘要:
This invention relates to a method for removing organic directing agents from as-synthesized molecular sieves comprising:(a) contacting said porous synthetic material with polar solvent having dissolved therein at least one cation donor, wherein said polar solvent is characterized by solubility parameters f.sub.d, f.sub.p, and f.sub.h wherein the values of solubility parameters f.sub.d, f.sub.p, and f.sub.h are defined by a circular region of the Teas diagram of Figure 41, said circular region having a center defined by the coordinates (f.sub.d =46, f.sub.p =22, f.sub.h =32) and encompassing about 21 percent of the total area of said Teas diagram of Figure 41, and wherein each of said sorbed templating agent and said cation donor are soluble in said polar solvent; and(b) holding said porous synthetic material, said nonaqueous polar solvent, and said cation donor of step (a) in contact at elevated temperature for a period of time sufficient to absorb at least a portion of said templating agent from said synthetic material.
摘要:
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.
摘要:
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.
摘要:
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.
