微生物法净化沼气的研究进展

Research Progress on Biogas Purification by Microorganism

在能源危机的背景下,作为重要生物能源之一的沼气已经越来越受到重视。沼气的应用目前已经不再局限于照明等传统用途。通过一系列的净化处理,沼气有了新的用途和价值,比如净化后并入天然气、作为汽车燃料等。微生物法处理沼气因其环境污染小、成本低和产生附加价值等优势成为比较热门的研究课题。文章主要对净化沼气中H2S和CO2的微生物分别进行了介绍并且对其诸多工艺中的关键影响因素进行了详细的阐述,结合现状分析提出了净化沼气中CO2和H2S的微生物在应用中存在的问题及其应用前景。

In the context of energy crisis,biogas as one of important biofuels has been gained more and more attentions,which is no longer confined to traditional lightening purpose.After a series of purification treatment,biogas can be used in many other aspects,such as using as an alternative for natural gas or car fuel.Biogas purification with microbiological method is becoming a popular research subject because of lower pollution,less cost and more additional products.Microorganism in biogas purification was recommended and the key factors of several processes were described in detail respectively.Combing with current analysis existing problem in application was pointed out and application prospect of purification of carbon dioxide and hydrogen sulphide removal by microorganism was proposed as well.
