摘要:

氨涉及农业和能源是生物经济的两大核心领域。不依赖化石资源生产、且无二氧化碳排放的清洁氨,既可用做绿色化肥原料,又能提供无碳排放的清洁燃料,有助于推动农业和能源绿色转型。本文从技术优势、主要生产技术、应用情况以及商业化挑战等方面对生物氨发展现状进行综述,结合我国实际情况分析发展生物氨作为农业和能源绿色转型重要手段的可行性。生物炼制农林废弃物得到生物炭和纸浆、生物聚酯、生物燃料等高价值产品,利用现有合成氨装置用生物炭制氢生产清洁氨,在经济上可与传统化石氨竞争。我国每年有10亿吨可利用农林废弃物做原料保障,生产6000万吨生物氨,可使农民增收1200亿元,创造10000亿元产值,减排2亿吨二氧化碳,对促进生物经济高质量发展具有重要作用。

Abstract:

Ammonia is involved in agriculture and energy two core areas of bioeconomy. Clean ammonia, which does not depend on fossil resources and has no carbon dioxide emissions, can be used as a green fertilizer and provide a clean fuel with no carbon emissions, which can help promote the green transformation of agriculture and energy. This paper reviews the current status of bioammonia development in terms of technical advantages, major production technologies, applications, and commercialization challenges, and analyzes the feasibility of developing bioammonia as an important tool for the green transformation of agriculture and energy in the context of China's actual situation. Biorefining agricultural and forestry wastes to obtain high-value products such as biochar and pulp, bio-polyester, bio-fuel, etc. The production of clean ammonia from biochar to hydrogen using existing ammonia synthesis plants can compete economically with traditional fossil ammonia. China has 1 billion tons of usable agricultural and forestry waste as raw material security every year, and the production of 60 million tons of bio-ammonia can increase farmers’ income by 120 billion yuan, create 10000 billion yuan of output value, and reduce 200 million tons of carbon dioxide, which plays an important role in promoting the high-quality development of bio-economy.
