我国生物天然气资源储量惊人,开发潜力巨大。但受困于观念和低产气率技术以及净化提纯工艺落后,产业的规模化、商业化并不理想。生物天然气的成熟趋势是城市液体有机垃圾、城市固体有机垃圾填埋气、工厂生物天然气,传统的农村沼气占比最小,而我国生物天然气发展才刚刚起步。以沼气为例,在原料来源上,传统的误区在于把畜禽动物粪便作为生产沼气的原材料,事实上粪便并不是理想的原料。而每年8-9亿吨计的闲置作物秸秆因技术设备等因素未能真正高效利用起来。在生物天然气开发利用较成熟的欧盟国家,能源作物(青贮玉米)、含油脂较多的厨余垃圾、屠
China’s biological reserves of natural gas amazing, huge potential for development. However, trapped in the concept of low gas production rate and purification technology and backward technology, the scale of the industry, commercialization is not satisfactory. The mature trend of bio-natural gas is that urban liquid organic waste, urban solid organic landfill gas, factory bio-natural gas and traditional rural biogas account for the smallest proportion, while the development of bio-natural gas in China has just started. Taking biogas as an example, the traditional misunderstanding about the source of raw materials is that animal manure is used as the raw material for producing biogas. In fact, the excrement is not an ideal raw material. Each year, 8-9 billion tons of unused crop straw are not really utilized due to technical equipment and other factors. In the more developed EU countries where bio-natural gas is exploited and utilized, energy crops (silage corn), kitchen waste containing more oil and fat,
