20090145810 | Addition of a Reactor Process to a Coking Process - A reactor process added to a coking process to modify the quantity or yield of a coking process product and/or modify certain characteristics or properties of coking process products. | 06-11-2009 |
20090152165 | System and Method for Introducing an Additive into a Coking Process to Improve Quality and Yields of Coker Products - Gas oil components, coking process recycle, and heavier hydrocarbons are cracked or coked in the coking vessel by injecting an additive into the vapors of traditional coking processes in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack or coke these components. The quenching effect of the additive can be effectively used to condense the highest boiling point compounds onto the catalyst(s), thereby focusing the catalyst exposure to these target reactants. With a catalyst to crack these highest boiling point materials, this mechanism can effectively increase the catalyst's selectivity, thereby increasing its efficiency and reducing catalyst requirements and costs. Selective, catalytic conversion of the highest boiling point materials in the coking process product vapors (coker recycle and/or ‘heavy tail’ of the heavy coker gas oil) may be accomplished with an exemplary embodiment of the present invention in varying degrees. Exemplary embodiments of the present invention can also provide methods to control the (1) coke crystalline structure and (2) the quantity and quality of volatile combustible materials (VCMs) in the resulting coke. Pet coke from this process may have unique characteristics with substantial utility. | 06-18-2009 |
20090209799 | System and Method of Introducing an Additive with a Unique Catalyst to a Coking Process - Gas oil components, coking process recycle, and heavier hydrocarbons are cracked or coked in the coking vessel by injecting an additive into the vapors of traditional coking processes in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack or coke these components. Modifications of the catalysts in the additive improve performance for certain desired outcomes. One exemplary embodiment of the present invention uses the olefin production capabilities from newly developed catalysts to increase the production of light olefins (e.g. ethylene, propylenes, butylenes, pentenes) for alkylation process unit feed, the production of oxygenates, and petrochemical feedstocks, such as plastics manufacture. Another exemplary embodiment of the present invention is the use of the olefin production from newly developed catalysts to improve the coker naphtha quality. A third exemplary embodiment of the present invention uses the cracking characteristics of newly developed catalysts to optimize the production of light gas oils, naphtha, and gases from the coking process. | 08-20-2009 |
20100170827 | Selective Cracking and Coking of Undesirable Components in Coker Recycle and Gas Oils - Undesirable gas oil components are selectively cracked or coked in a coking vessel by injecting an additive into the vapors of traditional coking processes in the coking vessel prior to fractionation. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack or coke these undesirable components that typically have a high propensity to coke. Exemplary embodiments of the present invention also provide methods to control the (1) coke crystalline structure and (2) the quantity and quality of volatile combustible materials (VCMs) in the resulting coke. That is, by varying the quantity and quality of the catalyst, seeding agent, and/or excess reactant the process may affect the quality and quantity of the coke produced, particularly with respect to the crystalline structure (or morphology) of the coke and the quantity & quality of the VCMs in the coke. | 07-08-2010 |
