The optimal utilization of biomass relies heavily on the specific material and individual needs. Cereal biomass by-products can potentially be employed in thermochemical processes such as pyrolysis and gasification. To compare biomass sources, ultimate analysis, biochar potential, proximate analysis, thermal gravimetric analysis, price per megajoule generated heat, surface texture, and availability are used. A global survey of biomass wastes and opportunities for heat generation is presented in the current article. Here, nine different cereal-based agricultural waste products (barley, wheat, millet, oats, rice, rye straw, sorghum straw/stalk, and maize cob) are studied. Cereal wastes are compared based on calorific value, water content, volatile matter, ash content and ash chemical composition, bulk density, charring properties, availability, and transportation. According to the estimate, 156 million metric tonnes per year, or 6% of India's total emissions, could be eliminated by rice husk alone. Wheat straws, on the other hand, can cut emissions by 2%. Additionally, processing these nine feedstocks might result in the production of 40 GW of electrical energy, which would increase the installed capacity of India's national electric grid by 9%.
生物质的最佳利用在很大程度上依赖于特定的材料和个人需求。谷物生物质副产物可以潜在地应用于热化学过程,如热解和气化。为了比较生物质资源,使用了最终分析、生物炭潜力、近似分析、热重分析、每兆焦耳产生热量的价格、表面纹理和可用性。本文对全球生物质废物和供热机会进行了调查。在此,研究了九种不同的基于谷物的农业废物产品(大麦、小麦、小米、燕麦、大米、黑麦秸秆、高粱秸秆/茎和玉米芯)。根据热值、含水量、挥发性物质、灰分含量和灰分化学成分、堆积密度、焦化特性、可用性和运输情况对谷物废物进行了比较。据估计,仅稻壳就可以消除印度每年 1.56 亿吨、占总排放量 6%的排放量。另一方面,小麦秸秆可以减少 2%的排放。此外,处理这九种原料可能会产生 40 吉瓦的电力,这将使印度国家电网的装机容量增加 9%。
