A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for a refining process; and (ii) adding an additive to the crude hydrocarbon.

Functionalized polymers containing polyamine succinimide for antifouling in hydrocarbon refining processes

A method for treating an emulsion of a hydrocarbon is disclosed. The method includes providing an emulsion of a crude hydrocarbon, and adding an additive to the emulsion to obtain a treated hydrocarbon.

Functionalized polymers containing polyamine succinimide for demulsification in hydrocarbon refining processes

In a process for producing mono-cycloalkyl-substituted aromatic compound, benzene and cyclic monoolefin are contacted with a catalyst under alkylation conditions to produce an effluent containing mono-cycloalkyl-substituted aromatic compound. The catalyst comprises a molecular sieve.

Process for producing a monocycloalkyl-substituted aromatic compound

A catalyst composition comprising: (i) a support; (ii) a first component comprising at least one metal component selected from Group 1 and Group 2 of the Periodic Table of Elements; and (iii) a second component comprising at least one metal component selected from Groups 6 to 10 of the Periodic Table of Elements, wherein the catalyst composition exhibits an oxygen chemisorption of greater than 50%.

Cyclohexanone dehydrogenation catalyst and process

In a process for the dehydrogenation of dehydrogenatable hydrocarbons, a feed comprising dehydrogenatable hydrocarbons is contacted with a catalyst comprising a support and a dehydrogenation component under dehydrogenation conditions effective to convert at least a portion of the dehydrogenatable hydrocarbons in the feed. The catalyst is produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid.

Dehydrogenation process

In a dehydrogenation process a hydrocarbon stream comprising at least one non-aromatic six-membered ring compound and at least one five-membered ring compound is contacted with a dehydrogenation catalyst produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid. The contacting is conducted under conditions effective to convert at least a portion of the at least one non-aromatic six-membered ring compound in the hydrocarbon stream to benzene and to convert at least a portion of the at least one five-membered ring compound in the hydrocarbon stream to paraffins.

A processes for producing a dehydrogenation reaction product stream comprising the step of contacting a hydrocarbon stream comprising cyclohexane and methyl cyclopentane with a dehydrogenation catalyst comprising at least one metal or compound thereof and at least one molecular sieve and under conditions effective to convert at least a portion of the cyclohexane to benzene and to convert at least a portion of the methyl cyclopentane to at least one paraffin. The hydrocarbon stream is produced by hydroalkylating benzene and hydrogen to form a hydroalkylation reaction product stream which is separated to yield the hydrocarbon stream.

This invention relates to a process for selectively hydrodesulfurizing naphtha feedstreams using a catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material.

Selective hydrodesulfurization process
