A process for power generation using a chemical looping combustion concept is integrated with heavy liquid fuel coking in a cracking reactor, and is configured such that petcoke deposits on metal oxide particles from the cracking reactor are used as fuel in the chemical looping combustion reaction. The process is also configured such that metal oxide particles provide the heat necessary for the cracking reaction to be initiated in the cracking reactor.

A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60° C. to about 200° C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260° C. to about 400° C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes.

A burner sub-system, a furnace comprising the same, a fuel combustion process and steam cracking process carried out in the furnace. The burner sub-system comprises a barrier wall segment between the burner tip and the flue-gas recirculation (“FGR”) duct, effectively blocking direct gas flow between the burner tip and the FGR duct opening, but without encircling the whole burner tip. The presence of the partial barrier wall has the advantage of preventing the temperature inside the FGR duct from becoming too high, while achieving low NOx emissions from the combustion process without overheating the burner tip because of reduced amount of heat reflection to the burner tip compared to an annular barrier wall. The invention is particularly useful in furnaces where hydrogen-rich fuel gas is combusted.

Heavy hydro-carbonaceous materials such as bitumen are upgraded in supercritical water in a continuous-flow reactor system. The present invention provides a reactor arrangement for and a method of converting bitumen and other highly viscous hydrocarbon containing materials into pumpable liquids to enable further processing of such materials while avoiding production of char. The process can be carried out in an underground reactor based on oil well technology. The reactor design and method facilitates mass transfer to dissolve bitumen in heated water and breaks down heavy hydrocarbons by controlling the temperature and pressure in zones within the flowing stream. The reactor may include an embedded electric heater.

A hydrocarbon material may be processed by a method that includes separating the hydrocarbon material into at least a lesser boiling point fraction, a medium boiling point fraction, and a greater boiling point fraction. The method may further include steam cracking at least a portion of the lesser boiling point fraction, catalytically cracking at least a portion of the medium boiling point fraction, and hydrocracking at least a portion of the greater boiling point fraction.
