目前工作的目的是研究通过添加二氧化碳来修改高温蒸汽气化过程的可行性，以尝试定制适合能源化学品生产行业的增值气体。这种集成过程从富含二氧化碳气氛下的蒸汽气化（CO2HTSG）的各个方面研究了高温蒸汽气化（HTSG）的概念。本研究旨在调查通过在实验室规模中部分回收二氧化碳（最好是从传统二氧化碳生产过程中产生）来改变现有 HTSG 气氛的有益或有害影响。研究气化的森林来源的非食用木质生物质 (WB)、瑞典煤 (SC) 和预处理的塑料废物 (PW) 及其弱混合物时，工艺参数对发生炉煤气质量、焦炭和焦油产量的影响。本研究的结果表明，当木质纤维素来源的材料与煤在高温/蒸汽条件下共气化时，会产生协同作用，而用二氧化碳蒸汽气化环境和高温进行的改进确实也会影响发生炉煤气的质量。这种效果取决于进料特性和蒸汽气化条件。似乎在高温下用蒸汽-二氧化碳进行气化降低了炭的反应性，但是与低百分比的生物质混合最大化了H2和CO2的产量。 © 2016 ETA-佛罗伦萨可再生能源公司。
Aim of the present work is to investigate the viability of modifying the high temperature steam gasification process by adding CO2 in an attempt to tailor value added gas suitable for the energy - chemicals production industry. Such an integrated process investigates the concepts of high temperature steam gasification (HTSG) with aspects from steam gasification under a rich in CO2 atmosphere(CO2HTSG). The present study aimed at investigating the beneficial or detrimental effect of modifying the existing HTSG atmosphere by partially recycling CO2 in lab scale and ideally emerging from a conventional CO2 production process. The effect of the process parameters on the producer gas quality, char and tar yields when gasified non-food woody biomass (WB) of forest origin, swedish coal (SC) and pre-treated plastic waste (PW) studied, as well as their weak blends. Results of the present study indicated synergies when materials of lignocellulosic origin with coal are co-gasified under high temperature/steam conditions, while the modified with CO2 steam gasification environment and at elevated temperature did affect also the quality of the producer gas. This effect depends on the feeding properties and steam gasification conditions, It seems that gasification at elevated temperature with steam-carbon-dioxide decreased the reactivity of chars however blending with biomass at low percentages maximized the H2 and CO2 production. © 2016 ETA-Florence Renewable Energies.
