摘要： A method of removing buffer gas from a mixture comprising the buffer gas and hyperpolarized noble gas is described. The method includes reacting the buffer gas to produce a reaction product different to the buffer gas. The buffer gas may be reactively removed by one or more of oxidation, reduction, polymerization and binding reactions with solid surfaces. The buffer gas may be molecular hydrogen and/or molecular nitrogen. Apparatus for carrying out the method are also disclosed.

摘要： The present invention is an apparatus and method for continuously separating, removing and purifying the solid residue, resulting from the conversion of hydrocarbons into carbon and hydrogen, from the homogeneous phase of different density contained in a cracking reactor with which said solid residue is not soluble, and where the separation of the solid carbon occur at two subsequent moments: a first separation occurs inside the reactor between the reaction products, including carbon, and the melting bath; a second separation then occurs outside the reactor between the carbon and the gas produced in a separation system (1) of the solid phase from the gas phase, where said separation system (1) also includes carbon purification.

摘要： The invention provides a process for producing a fermentable gas stream from a gas source that contains one or more constituent which may be harmful to the fermentation process. To produce the fermentable gas stream, the gas stream is passed through a specifically ordered series of removal modules. The removal modules remove and/or convert various constituents found in the gas stream which may have harmful effects on downstream removal modules and/or inhibitory effects on downstream gas fermenting microorganisms. At least a portion of the fermentable gas stream is preferably capable of being passed to a bioreactor, which contains gas fermenting microorganisms, without inhibiting the fermentation process.

摘要： The present disclosure relates to a cross-linked thermally rearranged polymer membrane and a method for preparing the same. The cross-linked thermally rearranged polymer membrane prepared according to the present disclosure has fluorine atoms distributed in a cross-linked thermally rearranged polymer membrane so as to have a concentration gradient from the surface and is formed into a three-layer structure consisting of a fluorine deposition layer, a transition layer and a thermally rearranged polymer base layer, thereby having remarkably increased selectivity as compared to the existing commercialized gas separation membrane and, particularly, enabling helium to be separated with high purity and recovery rate from a natural gas well, etc. even with a small membrane area, and thus being commercializable.

摘要： A process for separating components or a fluid mixture using membranes comprising a selective layer made from copolymers of an amorphous per fluorinated dioxolane and a fluorovinyl monomer. The resulting membranes have superior selectivity performance for certain fluid components of interest while maintaining fast permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon® AF, Hyflon® AD, and Cytop®.
