- Аннотация: Future developments in energy efficient processes and potential solutions for the energy-related environmental tasks are coupled with hydrogen-based technologies. Introductory parts of this chapter are focused on the specifics of H2 generation from biomass. Within the framework of this topic, three platforms are compared: conversion of simple sugars, cellulose and thermochemical conversion of biomass to hydrogen-containing gaseous mixtures. Three approaches for generation of biofuels starting materials for hydrogen production are considered: first one includes sugars and organic acids; second one includes lignocellulose, woodchips, etc.; finally, the third approach considers the possible routes of biomass gasification. In all cases the hydrogen needs to be separated (to be recovered) from the hydrogen-containing multicomponent gaseous mixtures of biogenic origin. Membrane-based gas separation processes are considered for H2 recovery from gaseous sources, including: (1) estimation of commercial and lab-scale polymeric membranes for recovery of H2 from gaseous mixtures, containing additionally CO2, CO, N2, CH4, H2S, with calculation of standard membrane process itself; (2) membrane contactors for hydrogen recovery from H2/CO2 mixtures; (3) combined membrane/ PSA systems for hydrogen recovery from gaseous mixtures of biogenic origin. It is shown that H2 recovery can be successfully realized as combination of standard membrane method (H2 preconcentrating) and PSA (H2 conditioning). Potential of whole process (biomass treatment and H2 recovery as a fuel) requires the active generation of knowledge for development of the desired bioprocesses and highly selective membranes.
