摘要
以化石燃料为主的能源消费日益增长,促使替代燃料技术的研究和开发,以减少人类对化石燃料的依赖,从而导致自然资源的污染。使用空气-蒸汽混合物进行部分氧化的小规模生物质气化是一个很好的替代方案,因为生物质是可持续能源生产的中性碳原料。本研究提出了从咖啡壳(CH)气化的实验研究中获得的结果,在10kw固定床气化炉中使用空气-蒸汽混合物进行部分氧化。对等效比(ER) (1.53 < ER < 6.11)和蒸汽燃料比(SF) (0.23 < SF < 0.89)进行了参数化研究。结果表明:增加顺丰度和ER可生成富CH4和H2、低CO的合成气;减小顺丰度和ER可降低气化炉燃烧区峰值温度;合成气高热值(HHV)范围为3112 ~ 5085 kJ/SATPm3,在SF = 0.87、ER = 4.09时达到最大值。在这些操作条件下(1.53 < ER < 6.11和0.23 < SF < 0.89), CH4的干基摩尔浓度为1.12 ~ 4.1%,CO为7.77 ~ 13.49%,H2为7.54 ~ 19.07%。其他物种则是微量的。
Adiabatic Fixed-Bed Gasification of Colombian Coffee Husk Using Air-Steam Blends for Partial Oxidation
The increasing energy consumption, mostly supplied by fossil fuels, has motivated the research and development of alternative fuel technologies to decrease the humanity’s dependence on fossil fuels, which leads to pollution of natural sources. Small-scale biomass gasification, using air-steam blends for partial oxidation, is a good alternative since biomass is a neutral carbon feedstock for sustainable energy generation. This research presents results obtained from an experimental study on coffee husk (CH) gasification, using air-steam blends for partial oxidation in a 10 kW fixed-bed gasifier. Parametric studies on equivalence ratio (ER) (1.53 < ER < 6.11) and steam-fuel (SF) ratio (0.23 < SF < 0.89) were carried out. The results show that increasing both SF and ER results in a syngas rich in CH4 and H2 but poor in CO. Also, decreased SF and ER decrease the peak temperature at the gasifier combustion zone. The syngas high heating value (HHV) ranged from 3112 kJ/SATPm3 to 5085 kJ/SATPm3 and its maximum value was obtained at SF = 0.87 and ER = 4.09. The dry basis molar concentrations of the species, produced under those operating conditions (1.53 < ER < 6.11 and 0.23 < SF < 0.89), were between 1.12 and 4.1% for CH4, between 7.77 and 13.49% for CO, and between 7.54 and 19.07% for H2. Other species were in trace amount.
