An integrated process for upgrading a hydrocarbon oil feed stream includes solvent deasphalting the hydrocarbon oil stream; processing the heavy residual hydrocarbons in a gasification unit to form syngas and gasification residue; hydrotreating the deasphalted oil stream to form a C.sub.3-C.sub.4 hydrocarbon stream, a light C.sub.5+ hydrocarbon stream, and a heavy C.sub.5+ hydrocarbon stream; dehydrogenating the C.sub.3-C.sub.4 hydrocarbon stream to form propylene and butylene; steam enhanced catalytically cracking the light C.sub.5+ hydrocarbon stream; steam enhanced catalytically cracking the heavy C.sub.5+ hydrocarbon stream; passing at least a portion of the light steam enhanced catalytically cracked stream, the heavy steam enhanced catalytically cracked stream, or both to a product separator to produce a olefin product stream, a naphtha product stream, and a BTX product stream; and processing the naphtha product stream in the aromatics complex to produce benzene and xylenes.

Disclosed is a biomass gasification and waste incineration integrated furnace, which relates to the technical field of biomass gasification and waste incineration, and includes a waste incineration furnace chamber and a biomass gasification furnace chamber. A mutual contact region exists between the waste incineration furnace chamber and the biomass gasification furnace chamber, and heat transfer can be realized between the waste incineration furnace chamber and the biomass gasification furnace chamber. Heat generated by the waste incineration furnace chamber is used for conduction to the biomass gasification furnace chamber, and excess heat generated by the waste incineration can be supplied to the biomass gasification furnace chamber for reactions therein, thereby reducing the heat additionally used by the biomass gasification furnace chamber and saving energy consumption.

A method for producing hydrogen and/or other gases from steel plant wastes and waste heat is disclosed. The method comprises the steps of providing molten waste from steel plant like molten slag in a reactor. The molten slag is contacted with water and/or steam in the presence of a reducing agent to form a stream of hydrogen and/or other gases. The hydrogen and/or other gases can then be extracted from the stream of gases from the reactor.

Disclosed are systems and methods having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while simultaneously enabling environmentally and sustainably sound practices. A hybrid thermochemical cycle couples staged reforming with hydrogen production and residue chlorination. The residues of the upgrading are chlorinated, metals of interest are removed and bulk material is re-mineralized. Through the residue chlorination process, various metals including rare earths are concentrated and extracted. Energy is retained through chemical synthesis such as hydrocarbon and metal and non-metal chloride production. Produced chemicals are later exploited by redox reactions in the operation of an integrated gasification flow battery.

Systems and methods are provided for integrated coking and gasification of a biomass feed in a three-vessel fluidized coking system under co-processing conditions so that biomass is co-fed with a conventional and/or mineral coker feed, such as a feed containing resid or heavy crude oil. It has been discovered that co-processing of a biomass feed can unexpectedly increase the reaction rate for coking of the conventional/mineral coker feed. This unexpected increase in reaction rate can allow for modification of how the three-vessel fluidized coking reaction system is operated. The resulting modification in operating conditions can allow for production of a modified and/or improved product slate from the fluidized coker. The modifications in the product slate can include an increase in total liquid products as well as a decrease in micro carbon residue and/or n-heptane insolubles in the total liquid products.

Processes for upgrading a hydrocarbon-containing feed. The feed and a first particle stream can be contacted under pyrolysis conditions to effect pyrolysis of the feed to produce a pyrolysis effluent that can include olefins and the particles, where coke can be formed on the particles. A first gaseous stream and a second particle stream can be obtained from the pyrolysis effluent. At least a portion of the first gaseous stream can be contacted with oligomerization catalyst particles under oligomerization conditions to effect oligomerization of at least a portion of olefins in the first gaseous stream.
