Emerging Trends in Porogens toward Material Fabrication: Recent Progresses and Challenges.

Fabrication of tailor-made materials requires meticulous planning, use of technical equipments, major components and suitable additives that influence the end application. Most of the processes of separation/transport/adsorption have environmental applications that demands a material to be with measurable porous nature, stability (mechanical, thermal) and morphology. Researchers say that a vital role is played by porogens in this regard.

Upgrading Biogas from Small Agricultural Sources into Biomethane by Membrane Separation.

The agriculture sector in Poland could provide 7.8 billion m of biogas per year, but this potential would be from dispersed plants of a low capacity. In the current study, a membrane process was investigated for the upgrading biogas to biomethane that conforms to the requirements for grid gas in Poland.

The Separative Performance of Modules with Polymeric Membranes for a Hybrid Adsorptive/Membrane Process of CO Capture from Flue Gas.

Commercially available polymeric membrane materials may also show their potential for CO capture by the association of the membrane process with other separation techniques in a hybrid system. In the current study, PRISM PA1020/Air Products and UBE UMS-A5 modules with membrane formed of modified polysulfone and polyimide, respectively, were assessed as a second stage in the hybrid vacuum swing adsorption (VSA)-membrane process developed in our laboratory. For this purpose, the module permeances of CO, N, and O at different temperatures were determined, and the separation of CO/N and CO/N/O mixtures was investigated in an experimental setup.

Data concerning adsorption equilibria of carbon dioxide, nitrogen and oxygen over a zeolite molecular sieve 13X for the modelling of carbon dioxide capture from gaseous mixtures by adsorptive processes.

Experimental adsorption isotherms of carbon dioxide, nitrogen and oxygen at 293, 313 and 333 K over a zeolite molecular sieve 13X Grace are presented. The data were used in the simulations of the hybrid VSA-membrane process for carbon dioxide capture from flue gas as presented in a related article entitled "The performance of a hybrid VSA-membrane process for the capture of CO from flue gas" [1]. A representative sample of ZSM 13X Grace (149.

Facile and scalable synthesis of nanoporous materials based on poly(ionic liquid)s.

A simple, fast, sustainable, and scalable strategy to prepare nanoporous materials based on poly(ionic liquid)s (PILs) is presented. The synthetic strategy relies on the radical polymerization of crosslinker-type ionic liquid (IL) monomers in the presence of an analogous IL, which acts as a porogenic solvent. This IL can be extracted easily after polymerization and recycled for further use.
