Membrane modules for CO 2 capture based on PVDF hollow fibers with ionic liquids immobilized

Performance improvement of PVDF hollow fiber-based membrane distillation process

Tolerance of Immobilized Yeast Cells in Imidazolium-Based Ionic Liquids

Ionic liquids (ILs) are considered as another ’green solvent’, after the supercritical carbon dioxide. They are a promising reaction medium for biocatalysis process. The tolerance of active cells in hydrophobic imidazolium-based ILs (1-R-3-methylimidazolium hexafluorophosphate, [RMim][PF6]) has been studied in this work. Calcium-alginate-entrapped baker’s yeast has been chosen as the model of l...

CO2 Capture by Dual Hollow Fiber Membrane Systems

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

Imidazolium-based ionic liquids immobilized on solid supports: effect on the structure and thermostability.

[BMI][PF(6)] has been supported on silica and alumina in order to study the effect of these classical oxide supports on the structure of the ionic liquid. A widespread characterization by TGA, DSC, XRD and solid NMR of thin films of [BMI][PF(6)] immobilized on these amorphous supports has evidenced a dramatic effect on the ionic liquid structure depending on the nature of the support. For the a...

Ionic Liquids for Carbon Dioxide capture: Absorbent Selection

Carbon dioxide (CO2) is one of the major contributors to the greenhouse effect. The power and industrial sectors combined account for about 60% of the global CO2 emissions [1]. CO2 capture and storage (CCS), which involves the processes of capture, transport and long-term storage of carbon dioxide, is a technology aimed at reducing greenhouse gas emissions from burning fossil fuels during indus...
