Hydrogen enriched gas production from biomass with inprocess carbon dioxide capture and catalyst regeneration using fluidized bed technology

“脱碳”能源供应是解决全球二氧化碳（CO2）排放的一种技术解决方案，在这种背景下，“氢能经济”的理念具有显著的优点。向氢（H2）经济发展的主要挑战是经济、可持续和环保地生产足够的氢气，以满足未来的需求。目前，氢气总产量的96%来自化石燃料。生物质的年总产量约为世界总能源消耗的8倍，是生产H2的巨大可再生来源（碳中和）。如果在这个过程中可以捕获二氧化碳，那么来自生物质的能源可以被认为是负碳的。该研究旨在开发一种新的方法，通过原位CO2捕获和催化剂再生，从农业/林业废物/生物质中连续生产H2。该工艺的新颖之处在于产生相对纯的氢气，二氧化碳作为副产品，无需任何外部进料。该工艺的另一个独特的特点是在气化炉中污染的催化剂的内部再生。因此，该技术将达到再生催化剂和生成无氮（N2）的H2和CO2的双重目的。这项研究的直接和间接影响将是广泛的。流态化是一种平台化技术，可以接受多种燃料。此外，这项研究还将降低N2O的排放，从而有助于减缓全球气候变化。随着廉价石油和天然气供应的减少，生物质发电可能成为一种可行的选择，而这项研究将有助于无故障运行并增加更多价值。总的来说，目前研究的目标是开发创新的环境友好技术，以利用生物质作为燃料和化学品。

"Decarbonizing" energy supply is a technological solution to address global carbon dioxide (CO2) emissions and in this context the idea of "hydrogen energy economy" has significant merit. The major challenge in moving towards a hydrogen (H2) economy is to produce sufficient H2 economically, sustainably, and environment-friendly to meet future demand. At present, 96% of the total H2 production is sourced from fossil fuels. Biomass with a total annual production of about 8 times the total world energy consumption, represents an immense and renewable source (carbon neutral) for the production of H2. If CO2 can be captured during the process, energy from biomass can be considered as carbon negative. The proposed research aims at developing a novel process for continuous production of H2 from agricultural/forestry wastes/biomass with in-situ CO2 capture and catalyst re-generation. Novelty of the process lies in the generation of relatively pure H2 with CO2 as a by-product without any external feed. Another unique feature of the process is internal regeneration of the catalyst, fouled in the gasifier. Thus, the technology will serve the twin purpose of regenerating the catalyst, and generation of nitrogen (N2) free H2 and CO2. The direct and indirect impacts of the research will be widespread. Fluidization is a platform technology that can accept various fuels. Furthermore, this research will also lower N2O emission and hence, will help to decelerate global climate change. Declining supply of cheap oil and gas may make bio-mass based power generator a viable option, while this research would help trouble free operation and add more value. Overall the target of the present research is to develop innovative environmentally friendly technologies for the utilization of biomass for fuels and chemicals.
