The invention relates to a method and a membrane module for the process-integrated oxygen generation during biomass gasification, the oxygen being generated by means of mixed ionic-electronic conductive ceramic membranes at high temperatures. The aim of the invention is to devise a method and a device for the energy-efficient generation of oxygen during biomass gasification in order to increase the efficiency of the entire process. According to the invention, the disadvantages of the prior art are overcome by a membrane module which is heated directly with the synthesis gas stemming from the biomass gasification. The heating, however, should cover only less than 20% typically less than 10% and, under optimum conditions, only approximately 5% of the heat requirement of the membrane module. The major part of the heat required to heat the fresh air is removed from the exhaust air of the membrane module by heat exchange. |
