    Abstract: Prepare a carbon molecular sieve membrane from a polyimide (e.g., a 6FDA/BPDA-DAM polyimide) that has a glass transition temperature of at least 400° C and includes a bridged phenyl compound for separation of hydrogen and ethylene from one another whether present as a pure mixture of hydrogen and ethylene or as components of a cracked gas. Preparation comprises two sequential steps a) and b). In step a), place a membrane fabricated from defect-free fibers of the polyimide in contact with an oxygen-containing atmosphere under conditions of time and temperature sufficient to produce a pre-oxidized and pre-carbonized polymeric membrane that is insoluble in hot (110 C) n-methylpyrolidone and at least substantially free of substructure collapse. In step b) pyrolyze the pre-oxidized and pre-carbonized membrane in the presence of a purge gas under conditions of time and temperature sufficient to yield a carbon molecular sieve membrane that has at least one of a hydrogen permeance and a hydrogen/ethylene selectivity greater than that of a carbon molecular sieve membrane prepared from the same membrane using only pyrolysis as in step b).

    Abstract: Methods for preparing a gas separation membrane system can include depositing a gas-selective membrane layer upon a surface of a tubular porous support, annealing the gas-selective membrane layer to form an annealed gas-selective membrane layer, polishing the annealed gas-selective membrane layer under a controlled polishing condition to form an abraded membrane surface, depositing another gas-selective membrane layer upon the abraded membrane surface of the tubular porous support, and successively iterating the annealing, polishing and depositing operations until a leak-tight membrane system is formed. The controlled polishing condition comprises utilizing a rotary fibrous buff that includes a plurality of abrasive particles adhered to a fibrous support with a polymeric binder.

    Abstract: Presented is a method for preparing a gas separation membrane system. This method involves depositing a membrane layer of gas-selective metal upon a tubular porous support followed by annealing the resulting layer of gas-selective metal. The resulting annealed membrane layer of gas-selective material is polished under a controlled polishing condition with an abrading medium that includes a structured abrasive article comprising a backing having bonded thereto an abrasive layer comprising a plurality of shaped abrasive composites that comprise abrasive grains dispersed in a polymeric binder. Another layer of gas-selective metal is then deposited upon the tubular porous support. The cycle of annealing, polishing and depositing is repeated through one or more cycles until a leak-tight membrane system is provided.

    Abstract: Carbon molecular sieves (CMS) membranes having improved thermal and/or mechanical properties are disclosed herein. In one embodiment, a carbon molecular sieve membrane for separating a first and one or more second gases from a feed mixture of the first gas and one or more second gases comprises a hollow filamentary carbon core and a thermally stabilized polymer precursor disposed on at least an outer portion of the core. In some embodiments, the thermally stabilized polymer precursor is created by the process of placing in a reaction vessel the carbon molecular sieve membrane comprising an unmodified aromatic imide polymer, filling the reaction vessel with a modifying agent, and changing the temperature of the reaction vessel at a temperature ramp up rate and ramp down rate for a period of time so that the modifying agent alters the unmodified aromatic imide polymer to form a thermally stabilized polymer precursor.
