Bio-based copolymers for membrane end products for gas separations

Descripción del proyecto

Membranas de separación química eficientes basadas en copolímeros de alto rendimiento

Los procesos industriales de separación química, como la destilación, suponen entre un 10 y un 15 % del consumo energético anual en el mundo. La separación química basada en membranas puede resultar un orden de magnitud más eficiente en materia de energía que la activada por calor. Para que su uso se extienda, se requieren materiales con propiedades funcionales específicas para una determinada aplicación. El proyecto BIOCOMEM, financiado con fondos europeos, se propone sintetizar y diseñar precursores de copolímeros de base biológica que puedan convertirse en membranas con unas propiedades mecánicas, térmicas y de permeación mejoradas. El estudio también abordará el reciclaje de los polímeros de las membranas por métodos químicos y enzimáticos.

Objetivo

The main objective of the BIOCOMEM is to develop and validate gas separation membranes at TRL 5 using bio- based polyether-block-amide copolymers (PEBAs) specially designed to give: higher processability into monolithic hollow fiber membrane; higher gas separation performance, higher resistance to chemical attack (aging), higher bio- based content.
The project started with a bio-based PEBA copolymer (A, Reference bio-PEBA) that is already avaible from Arkema at TRL8 and shows (at TRL3 - dense flat sheet membrane) better gas permeation properties than the fossil fuel counterparts (PEBAX® MV 1074 and PEBAX® MH1657). Several synthesis pathways were followed to further improve the properties and gain the necessary added value for market competitiveness. The modification of the chemical structure was done systematically with the purpose to fully understand the relation between the chemical structure, morphology and properties. In one research line (B, New bio-PEBAs Pathway 1) the polyether block was be kept constant, the same as for the reference bio-PEBA, and only the polyamide block was modified using bio- based monomers with aromatic/cycloaliphatic structure. The main objective of the first research line was to induce spinnability by making polymers with better solubility keeping at least similar mechanical properties compared to the reference polymer. In a parallel research line (C, New bio-PEBAs Pathway 2), the polyamide part was kept constant as for the reference bio-PEBA (i.e. poly(11-undecanoic acid)), and the chemical structure of the polyether block was modified using monomers derived from lignin as a starting point to connect hydrophilic chains. The objective of the second research line is to produce a polyamide-polyether block copolymer with bio-based components in both blocks and the processability into monolithic hollow fiber membranes was evaluated. At M18 it was demonstrated lignin-polyether-block-PA11 PEBAs could not be prepared successfully. Therefore, a modified prototype C was developed by copolymerization of a biobased polyamide synthesized from diethyl sebacate, diethyl galactarate (GalX) and 1,10-diaminodecane with a commercial, biobased poly(1,3 propanediol) polyether derived from starch (Velvetol®).
