Methods and systems are provided for making gasoline. The method includes converting a resid-containing feed to a first fuel gas and a fluid coke in a fluidized bed reactor; gasifying the fluid coke with steam and air to produce a second fuel gas, said second fuel gas comprising a syngas; contacting the first fuel gas with a first conversion catalyst under first effective conversion conditions to form an effluent comprising C.sub.5+ hydrocarbon compounds; and converting the syngas to gasoline boiling range hydrocarbons by converting the syngas to a methanol intermediate product.

Methods and systems are disclosed for upgrading a paraffinic feed to gasoline. The system includes a fluidized cracker receiving a paraffin-containing feedstream and producing an olefin product therefrom, the olefin product comprising C4 olefins; a separation system receiving the olefinic product and separating an olefin-containing feed therefrom, the olefin-containing feed having an olefin content of at least about 10 wt %; and an oligomerization reaction system receiving the olefin-containing feed and exposing the olefin-containing feed to a conversion catalyst under first effective conversion conditions to form an oligomerized olefin effluent comprising C.sub.5+ olefinic compounds.

The present invention provides a process and a system for coking and simultaneous upgrading of a heavy hydrocarbon feedstock. More particularly the present invention relates to a process of cracking heavy hydrocarbon feedstock employing high heat carrier, incorporated with weak acid sites for improving the liquid yield and reducing coke yield. The feedstock is vaporized and brought in contact with a heat carrier material to produce a product stream and separating the product stream from the particulate heat carrier, regeneration of the particulate heat carrier to the extent of 10-30% and collecting a gaseous and liquid product from the product stream.

Systems and methods are provided for performing steam cracking on a feed while using direct heating of the reaction environment. The heating of the reaction environment can be achieved in part by transporting heat transfer particles from a heating zone to cracking zone. This can be performed in a fluidized bed reactor, a moving bed reactor, a riser reactor, or another type of reactor that can allow for catalyst movement and regeneration during operation.

A method for forming catalytically treated pyrolytic vapor product from pyrolyzable material, the method comprising burning fuel in a fluidized bed boiler, thereby heating some particulate material; transferring at least some of the heated particulate material or some other heated particulate material to a pyrolysis reactor to pyrolyze some pyrolyzable material in the pyrolysis reactor; and conveying at least some pyrolytic vapor through a catalyst bed comprising catalyst material; and conveying at least part of the formed side products upstream back to the process; thereby producing the catalytically treated pyrolytic vapor product in an resource efficient manner. In addition, a system configured to produce catalytically treated pyrolytic vapor product from pyrolyzable material. The system comprises a fluidized bed boiler; a pyrolysis reactor; a catalytic reactor; means for conveying some heated particulate material to the pyrolysis reactor; a pipeline for conveying at least some pyrolytic vapor from the pyrolysis reactor into the catalytic reactor and means for conveying at least part of the formed side products upstream back to the process for recovering heat and chemical energy bound to the side products.

Present invention relates to a novel process for upgrading a residual hydrocarbon oil feedstock having a significant amount of Conradson Carbon Residue (concarbon), metals, especially vanadium and nickel, asphaltenes, sulfur impurities and nitrogen to a lighter more valuable hydrocarbon products by reducing or minimizing coke formation and by injecting fine droplets of oil soluble organo-metallic compounds at multiple elevations of the riser with varying dosing rates.

A fluid coking operation for converting bitumen to lighter hydrocarbons can be controlled or monitored using a stripper fouling indicator to mitigate foulant accumulation on the sheds of the stripper within the lower section of the coker and avoid flooding. The stripper fouling indicator can be linked to the liquid carry-under to the stripper which can be correlated to certain measurable variables such as which feed nozzles are used for bitumen injection, solids circulation rate of the coke particles, and reactor temperature. The coking can be kept below the stripper fouling indicator to avoid flooding while operating with high yield and performance.
