A moving bed reactor is provided that can allow facilitate performing a reaction involving a three-phase flow under co-axial flow conditions for the solid and liquid portions of the three phase flow, while the gas portion of the three-phase flow is exposed to the solids under radial flow conditions. Methods for using such a moving bed reactor to perform a reaction, such as upgrading of a feed to distillate products, are also provided.

Moving bed reactor for processing three phase flows

Multiphase separators, processes and systems for converting an oxygenate and/or olefin feedstock to a hydrocarbon product are described herein.

Multiphase separator and methods of use thereof for producing hydrocarbons from oxygenates and olefins

Systems and methods are provided for controlling the flow and transport of catalyst particles within a reaction system. The flow of catalyst particles can be managed using a rotating disc or wheel that is configured within a roller volume to allow for control over the rate of catalyst flow while reducing or minimizing attrition of the catalyst particles. This can be achieved in part by maintaining a relationship between the center of the rotating disc, the inlet for catalyst particles to the roller volume, and the top wall of the roller volume so that catalyst particles are not exposed to compressive forces and/or abrasion during rotation of the disc. Additionally or alternately, the disc and roller volume surfaces can be configured to reduce or minimize the potential for catalyst particles to become trapped in 'dead space' regions within the roller volume. By using a disc to provide force for transport of particles through the roller volume, the speed of catalyst movement can be controlled at relatively slow catalyst flow rates with a reduced or minimized risk for clogging or plugging within the roller volume.

Apparatuses and processes for converting an oxygenate feedstock, such as methanol and/or dimethyl ether, in a fluidized bed containing a catalyst to hydrocarbons, such as gasoline boiling components, olefins and aromatics are provided herein.

Apparatus and process for producing gasoline, olefins and aromatics from oxygenates

Apparatuses and processes for converting an oxygenate feedstock, such as methanol and dimethyl ether, in a fluidized bed containing a catalyst to hydrocarbons, such as gasoline boiling components, olefins and aromatics are provided herein.

The present invention relates to an improved gasifier reactor design. In particular, the present invention relates to improved design of gasifier reactor faceplates, gasifier reactor walls, gasifier reactor cooling tubes, and gasifier reactor walls with integrated cooling channels. The present invention utilizes aluminum nitride and/or aluminum nitride/metal composite materials which promote many benefits to the present design herein, including improved corrosion and erosion resistively as compared to high alloy metal materials.

Corrosion resistant gasifier components

The present invention relates to an improved gasifier injection system. In particular, the present invention provides an improved apparatus and operating scheme to improve the control flow of solid particulates in a multi-burner gasifier. The system also provides for integrated flow control and emergency shutoff in the case of abnormal operating conditions or unexpected backflow of the process burners. This improved design simplifies the mechanical systems required for large multi-burner gasifiers thus providing a more reliable and compact gasifier feed system. In preferred embodiments, the gasifier hydrocarbon feed is substantially in a solid particulate state and is preferably comprised of coal, petrochemical coke, and/or solid biomass.

Method of injecting fuel into a gasifier via pressurization

A solids supply system having a solids deaeration zone and a solids pump zone, and a method for supplying the solids e.g., pulverized dry coal, to an application, e.g., gasification process. The solids deaeration zone includes a container having a passageway defined by one or more sloped walls. The solids deaeration zone is operable to deaerate and convey the solids to the solids pump zone. In the solids deaeration zone, the solids become sufficiently compacted prior to and upon entry into the solids pump zone to be effectively conveyed through the solids pump zone.

Passive solids supply system and method for supplying solids

Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. The processes herein allow a simple and effective method for removing the majority of coke formed in the alkali metal reagent reactions with the hydrocarbon feedstreams. This makes it cost effective to run such processes at higher severities (which result in higher coke production) thereby resulting in increased amounts of valuable converted hydrocarbon product yields. The process improvements herein may also be used to increase total throughput through a unit due to the ability to effectively manage higher coke content in the reaction products.

Alkali metal hydroprocessing of heavy oils with enhanced removal of coke products

The present invention relates to a process for desulfurizing heavy oil feedstreams with alkali metal compounds and improving the compatibility of the to stream components in either the feed stream, an intermediate product stream, and/or the reaction product stream in the desulfurization process. The present invention utilizes a high stability aromatic-containing stream that is preferably added to the heavy oil prior to reaction with the alkali metal compounds. The resulting stream resists precipitation of reaction solids in the desulfurization reactors. Even more preferably, the desulfurization system employs at least two desulfurization reactors in series flow wherein the high stability aromatic-containing stream is contacted with the reaction product from the first reactor prior to the second reactor, wherein the first reactor can be operated at a higher severity than without the use of the high stability aromatic-containing component stream.

Process for producing a high stability desulfurized heavy oils stream

The invention relates to improved bitumen recovery processes and systems. One process provides for operation of a bitumen froth treatment plant at optimum shear rates in the feed pipe carrying the bitumen froth to the froth settling unit. Another process provides for optimizing the design of a bitumen froth treatment plant by optimizing the diameter of the feed pipe to impart an optimum shear rate to the bitumen froth mixture and further optimizing the volume of the feed pipe to impart an optimum residence time for the bitumen froth stream in the feed pipe. An optimal plant design is also disclosed, the plant including optimal diameter and volume of the feed pipe.

The solids deaeration zone is operable to deaerate and convey the solids to the solids pump zone. In the solids deaeration zone, the solids become sufficiently compacted prior to and upon entry into the solids pump zone to be effectively conveyed through the solids pump zone.

Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. After separation of the spent alkali metal reagent, the resulting product can have suitable characteristics for pipeline transport and/or further refinery processing.
