Review on the preparation of carbon membranes derived from phenolic resins for gas separation: From petrochemical precursors to bioresources

Membrane processes, whose low energy and operating costs make them competitive for gas separation compared to other conventional methods such as pressure swing adsorption, cryogenic distillation or amine absorption, allows high-purity be obtained in a sustainable continuous manner. Similarly, resin-derived carbon membranes with molecular sieving properties have improved the selectivity permeability of dense membranes, well having high chemical thermal resistance. In this review, an overview preparation phenolic resin-based their performance is presented, particularly processes involving permanent gases hydrogen purification, air separation, natural gas/biogas sweetening dioxide capture. Moreover, bioresources already proven synthesis “greener” resins some based on bioresource-derived are also reported discussed work. This review will summarise development provide clear future direction “green” research.
