摘要:
A method for the coproduction of oxygen, hydrogen and nitrogen using an ion transport membrane is provided. This method includes separating a compressed, hot air stream in an ion transport membrane, thereby producing a product oxygen stream and a hot nitrogen rich stream; utilizing at least a portion of the hot nitrogen rich stream as a heat source for reforming a hydrocarbons stream, thereby producing a syngas stream and a warm product nitrogen stream; and separating the syngas stream into a product hydrogen stream and a carbon dioxide rich stream.

A method for producing a hydrogen gaseous fuel from kinetic and/or potential energy recovered from a vehicle powered by a four stroke Diesel engine fitted with a Jacobs engine brake during a deceleration stage. Such a method comprises the following stages: a) providing a preheated steam flow; b) providing a gas flow from at least one chemical species used as preheated carbon and hydrogen source; c) mixing the gas flow from at least one chemical species used as carbon and hydrogen source from stage a) with the steam flow from stage b).

The present invention relates to a method and system for converting gas to liquids and fractionating crude oil or condensate. Advantageously, it includes hydroprocessing at least a portion of the fractionated product and at least a portion of the Fischer-Tropsch products in the same hydroprocessor. Among other advantages the present invention provides for improved output quality for diesel and/or naphtha, reduced transportation and/or storage costs, and/or enhanced energy efficiency.

The present disclosure is directed to steam reformers for the production of a hydrogen rich reformate, comprising a shell having a first end, a second end, and a passage extending generally between the first end and the second end of the shell, and at least one heat source disposed about the second end of the shell. The shell comprises at least one conduit member comprising at least one thermally emissive and high radiant emissivity material, at least partially disposed within the shell cavity. The shell further comprises at least one reactor module at least a portion of which is disposed within the shell cavity and about the at least one conduit member and comprises at least one reforming catalyst. The disclosure is also directed to methods of producing a hydrogen reformate utilizing the steam reformers, comprising the steps of combusting a combustible mixture in a burner to produce a combustion exhaust that interacts with the steam reactor module(s) through surface to surface radiation and convection heat transfer, and reforming a hydrocarbon fuel mixed with steam in the steam reformers to produce a hydrogen-containing reformate. The present disclosure is further directed to reactor modules for use with the above steam reformers and methods of producing a hydrogen reformate.
摘要:
Disclosed is a process for the production of hydrogen in a reactor system comprising a steam reforming reaction zone comprising a reforming catalyst and a membrane separation zone comprising a hydrogen-selective membrane. The process involves a reaction system of so-called open architecture, wherein the reforming zone and the membrane separation zone operate independently of each other. The invention provides the heat for the reforming reaction through heat exchange from liquid molten salts, preferably heated by solar energy.
摘要:
In some implementations, a method for separating components includes receiving off-gas from a Fischer-Tropsch hydrocarbon synthesis reaction process. The off-gas is scrubbed with a light oil at least proximate atmospheric temperature to substantially remove a mixture of C 3 and C 4 . The C 3 and C 4 are separated from the mixture into two separate streams using distillation columns in a Fischer-Tropsch system.
摘要:
An improved, economical alternative method to supply steam and methane to a steam methane reformer (SMR) is accomplished by a combination of procedures, wherein product gas from a steam hydro-gasification reactor (SHR) is used as the feedstock for the SMR by removing impurities from the product stream from the SHR with a combination of autothermai reforming, condensation removal and gas cleanup procedures that operates substantially at process pressures and at a temperature above the boiling point of water at the process pressure, is located between the SHR and SMR. In another embodiment, a method is provided for controlling the H2/CO syngas ratio obtained from a steam methane reformer (SMR) by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR.
