1. A process comprising providing a reactor process in association with a coking process wherein said reactor process comprises a modification of a traditional vapor line between a coke drum and a fractionator to perform as a reactor vessel, to promote chemical reactions of a process stream from said coking process and return products of said reactor process to said coking process to cause a modification of a quantity, a yield characteristic, a quality, or a property of a product resulting from said coking process. 2. A process of claim 1 wherein said reactor process is selected from the group consisting of riser cracking reactor, fluidized bed reactor, ebullated bed reactor, fixed bed reactor, bunker reactor, plug flow reactor, or other reactor processes. 3. A process of claim 1 wherein said coking process is selected from the group consisting of delayed coking, fluid coking, flexicoking, or other coking processes. 4. A process of claim 1 wherein said modification of said product resulting from said coking process is caused by the introduction of an additive to said reactor process, said additive comprising catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier fluid(s), or any combination thereof. 5. A process of claim 4 wherein said catalyst is an acid based catalyst that provides propagation of carbon based free radicals that actively participate in a mechanism of a cracking reaction, a coking reaction, or any combination thereof. 6. A process of claim 4 wherein said catalyst is selected from the group consisting of alumina, silica, zeolite, calcium compounds, iron compounds, activated carbon, crushed pet coke, or any combination thereof. 7. A process of claim 4 wherein said catalyst is selected from the group consisting of new catalyst, FCCU equilibrium catalyst, spent catalyst, regenerated catalyst, pulverized catalyst, classified catalyst, impregnated catalysts, treated catalysts, or any combination thereof. 8. A process of claim 4 wherein said catalyst has particle size characteristics to prevent entrainment in the product vapors, achieve fluidization in said process reactor, or any combination thereof. 9. A process of claim 4 wherein said catalyst has sufficient porosity and other characteristics to catalyze reactions with a reactant in a liquid phase, a vapor phase, a semi-solid phase, a solid phase, or any combination thereof. 10. A process of claim 4 wherein components of said additive are blended using a batch or continuous mixing process prior to introduction of said additive to said reactor process. 11. A process of claim 1 wherein said coker process stream is selected from the group consisting of coke drum product vapors, coker recycle, coker fractionator bottoms, coker naphtha, light coker gas oil, heavy coker gas oil, extra heavy coker gas oil, partially condensed coke drum product vapors, or any combination thereof. 12. A process of claim 1 wherein said reactor process provides sufficient process conditions to promote cracking reactions, coking reactions, pyrolysis reactions, hydrogenation reactions, hydrogenolysis reactions, hydrolysis reactions, addition reactions, dehydrogenation reactions, condensation reactions, polymerization reactions, aromatization reactions, oligomerization reactions, isomerization reactions, or any combination thereof. 13. A process of claim 1 wherein hydrogen is added to said reactor process to enhance chemical reactions caused by said reactor process. 14. A process of claim 1 wherein an operating temperature and operating pressure of said reactor process are maintained for desired reactions. 15. A process of claim 14 wherein said operating temperature is maintained between 600 and 900 degrees Fahrenheit. 16. A process of claim 14 wherein said operating temperature of the reactor process is maintained by a fired heater of said coking process, a new fired heater, removal of insulation on process equipment of said coking process, a heat exchanger to withdraw excess heat, other heat exchange equipment, or any combination thereof. 17. A process of claim 14 wherein said operating pressure is maintained by a pressure of said coking process, a pressure of a compressed fluid to said reactor process, a pressure created by said catalytic reactions, a pressure from an increase in volume of said process stream, or any combination thereof. 18. A process of claim 1 wherein said modification of said product resulting from said coking process is caused by catalytic cracking, catalytic coking, thermal cracking, thermal coking, or any combination thereof. 19. A process of claim 1 wherein said modification of said product resulting from said coking process is used to reduce recycle in the coking process, reduce heavy components in the coker gas oils, or any combination thereof. 20. A process of claim 1 wherein a process stream external to said coking process is added to said reactor process to enhance chemical reactions or provide excess reactants in chemical reactions. 21. A process of claim 20 wherein said process stream external to said coking process is selected from a group consisting of hydrogen, gas oils, FCCU slurry oils, FCCU cycle oils, extract from aromatic extraction units, coker feed, bitumen, other aromatic oils, coke, activated carbon, coal, carbon black, or any combination thereof. 22. A process comprising providing a reactor process in association with a coking process: wherein said reactor process comprises a modification of coker process equipment to act as a reactor vessel, to promote chemical reactions of a process stream from said coking process and return products of said reactor process to a fractionator of said coking process; andwherein said coker process stream is selected from the group consisting of coke drum product vapors, coker recycle, coker fractionator bottoms, coker naphtha, light coker gas oil, heavy coker gas oil, extra heavy coker gas oil, partially condensed coke drum product vapors, or any combination thereof;to cause a modification of a quantity, a yield characteristic, a quality, or a property of a product resulting from said coking process. 23. A process comprising: providing a coking process stream from a delayed coking process;providing said coking process stream to a reactor vessel;injecting an additive comprising catalyst said reactor vessel;producing a reactor process output from said reactor vessel; andproviding said reactor process output to a fractionator.
