摘要

Many economic and social benefits are derived using bio-energy charcoal residue to scrub CO2 from exhaust streams.

利用生物能源的木炭残留物从排发气流中来除去二氧化碳会产生很多的经济和社会益处。

Charcoal can be a beneficial soil amendment as it could be stable for thousands of years. When utilized in combination with aqueous ammonia scrubbing system for CO2, the two create a nitrogen fertilizer. This novel material has environmental advantages over typical fertilizers, which release significant quantities of CO2 during their manufacture.

木炭可以是一种有益的泥土改善品,其功能在上千年里能保持稳定。当其与含水氨在系统中共同利用来除去二氧化碳,它们会制造一种氮肥料。这种新物质与典型的肥料相比有环境上的优势,因为典型的肥料在生产过程中会释放大量的二氧化碳。

The CO2 and aqueous gas phase ammonia create a solid fertilizer deep inside the porous charcoal, allowing traditional coating technologies to produce a slow controlled release nitrogen source. Charcoal and fertilizer reduce the typical nitrous oxide (GHG) emissions from agricultural fertilizer use. In certain soils, CO2 will mineralize for long term capture in addition to the charcoal carbon. Prior work used renewable hydrogen to maximize CO2 capture.

二氧化碳和气态含水氨制造一种在多孔木炭深深内部的固体肥料,从而让传统的外层覆盖技术产生一种缓慢释放氮资源的机制。木炭和肥料减少了农业肥料使用中典型的氮化物的释放量。在特定的泥土中,二氧化碳可被矿物化,从而可以与木炭的碳一样被长期固定在土壤中。早期研究中用可再生的氢来固定二氧化碳。

A new less capital-intensive method utilizes commercially available aqueous ammonia and charcoal produced from co-firing biomass gases for NOx reduction applications. The dry catalytic aqueous ammonia char removes CO2/SOx/NOx from fossil fuel combustion while producing of a superior carbon-nitrogen-sulfur fertilizer. Whether utilizing CO2 from fossil fuel combustion or from biomass conversion technologies, this system represents a multi-facet utilization and storage rather than sequestration.

一种新的少一些资本密集型的方式是利用商业可得的含水氨和木炭,它们是用替代燃料生物气体来减少氮化物。干燥接触反应的含水氨木炭从燃料燃烧中除去二氧化碳、硫化物和氮化物,与此同时,一种很好的碳-氮-硫肥料产生了。无论是从燃料燃烧中利用二氧化碳,还是生物量转换技术,这套系统体现了不只是碳的固化,而是代表了多方面的利用功能。

Some benefits include: fast implementation cycle, comparatively low-cost, restoration of eroded topsoil and a closed cycle for return of soil micronutrients. Increases in soil fertility, nutrient uptake (cation exchange), microbial activity, water holding capacity, and crop yields are found. Decreases in nutrient leaching, farm chemical runoff and GHG emissions lead to improved air/soil/water quality and support for other terrestrial sequestration efforts.

一些优点包括:快速的实行周期,相比较低成本,恢复腐蚀的土壤表层和一个归还泥土微型营养的循环周期。增加泥土肥沃、营养汲取(阳离子交换)、微生物活动、容纳水能力、以及农作物产量。减少土地营养和化学品的淋失。也可减少GHG的排放。从而导致改进空气/泥土/水的质量以及为其它一些地球上的净化努力而贡献力量。
