摘要： This invention relates to a process and system for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) subjecting a vacuum resid to a first thermal conversion in a thermal conversion reactor (such as delayed coker, fluid coker, Flexicoker™, visbreaker and catalytic hydrovisbreaker) where at least 30 wt % of the vacuum resid is converted to material boiling below 1050° F. (566° C.); (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being integrated into a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to the radiant furnace in said steam cracking furnace; and (d) recovering at least 30 wt % olefins from the material exiting the radiant furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).

摘要： The morphology of petroleum cokes produced by the delayed coking of feeds produced from extra-heavy crude sources such as those from the Venezuela Orinoco Heavy Oil Belt can be controlled to produce a less dense coke which is less likely to inflame in the coke pit or in subsequent handling. An aqueous solution of an alkali metal or alkaline earth metal carbonate salt when added to a feed of this type which would normally produce a dense coke product is effective to produce a quenchable coke product of lower density and higher porosity, usually in compact, granular form permitting it to be readily discharged from the drum.

摘要： The process of this invention comprises following steps; (1) heavy oil is converted in a low temperature coking reactor operator at 470*- 550*C and including a fluidized bed containing particles of an alkali metal carbonate compound into particles of carbonaceous residue containing desulfurized decomposition gas, desulfurized light oil, particles of the alkali metal carbonate compound and volatile components; (2) at the same time a portion of the sulfur contained in the heavy oil is fixed to form an alkali metal sulfide by the action of the alkali metal carbonate compound whereby to recover the desulfurized decomposition gas and the desulfurized light oil from the raw temperature coking reactor; (3) the particles of carbonaceous substance residue containing the alkali metal carbonate compound is transferred from the low temperature coking reactor into a high temperature coking reactor including a fluidized bed; (4) the carbonaceous substance residue is treated at an elevated temperature in the bed operating at 550* - 700*C for forming coke particles containing the alkali metal carbonate compound and desulfurized light substance; (5) the desulfurized light substance is admitted into the low temperature coking reactor whereby to recover the desulfurized gas and the desulfurized light oil; (6) the coke particles are transferred into an alkali metal sulfide regeneration reactor from the high temperature coking reactor; (7) the coke particles are contacted in a high temperature bed operating at 600*-800*C with high temperature fuel gas transferred from a heating and gasifying reactor thereby converting the alkali metal sulfide compound which has fixed the sulfur in the heavy oil contained in the coke particles into the alkali metal carbonate compound thus releasing the fixed sulfur as hydrogen sulfide; (8) the hydrogen sulfide containing fuel gas is recovered from the alkali metal sulfide regeneration reactor; (9) the coke particles are transferred into a heating and gasifying reactor provided with a fluidized bed; (10) most of the coke in the coke particles is converted into heated fuel gas in the fluidized bed operating at 700*-1,000*C; (11) the fuel gas is transferred into the alkali metal sulfide regeneration reactor thus recovering the fuel gas as hydrogen sulfide containing fuel gas; and (12) the alkali metal carbonate containing particles from which most of the coke has been removed are circulated through the high temperature coking reactor.

摘要： Hydrocarbon feedstocks, preferably heavy hydrocarbon feedstocks containing sulfur, are cracked at elevated temperatures in a novel regenerable alkali metal carbonate molten medium containing a glass-forming oxide, such as an oxide of boron, to produce high yields of light olefins such as ethylene, which olefins are useful in the synthesis of polymers and other valuable chemicals. The carbonaceous materials, i.e. coke, which are formed and dispersed in the molten medium during the cracking operation are gasified by contacting a portion of said carbonaceous materials with a gaseous stream containing oxygen, steam or carbon dioxide at temperatures of from about above the melting point of said medium to about 3000.degree.F. in order to regenerate the melt. Preferably, the amount of glass-forming oxide expressed as the oxide thereof, present in the alkali-metal carbonate melt is maintained in the range of from about 0.1 to about 25 weight percent based on the total weight of the molten medium in order to increase the overall dispersion of the carbonaceous materials which are formed in the molten medium during the cracking reaction.
