Technical development on synthetic natural gas production from biomass (Bio-SNG)

Abstract

Abstract: The production of synthetic natural gas from biomass (Bio-SNG) by gasification is an attractive option to reduce CO2 emissions and replace declining fossil natural gas reserves. Bio-SNG via gasification, cleaning, conditioning, methanation of the synthesis gas, and subsequent upgrading can be regarded as a ‘second generation’ renewable energy technology. According to the comprehensive analysis on synthetic technique of Bio-SNG，the process flowsheet abroad are analyzed and compared．Some suggestions are provided on development and applications of Bio-SNG technologies.

Key words: biomass, gasification, methanation, synthetic natural gas

摘要： 生物质合成天然气（Bio-SNG）是一种可再生的绿色燃气，可混入现有天然气管网运输使用，也可用作车用燃料，其制备技术被认为是“第二代生物燃料”技术。本文对生物质气化合成天然气的主要技术工艺进行分析与总结，介绍了目前国内外发展现况，着重对已进行中试规模验证的技术工艺流程进行详细介绍。但目前该技术仍处于刚刚起步阶段，我国目前尚没有生物质气化合成制备Bio-SNG的报道，发展适合制备Bio-SNG的生物质气化、净化技术、尤其是开发可经受多种杂质成分的甲烷化催化剂及工艺技术仍是今后的重要研究方向，仍需要长期的探索和验证。
