在未来相当长的一段时间内,煤气化仍是大规模制取氢气的主要途径。目前,常规煤气化过程得到的是H2、CO和CO2为主的混合气,需要通过净化、变换和分离工艺才能得到洁净的氢气,工艺过程复杂。采用连续式超临界水反应装置,以质量分数为20%的水煤浆为反应原料,考察了Ca/C摩尔比和温度对褐煤制氢系统的影响。试验结果表明:Ca(OH)2不仅可以很好地固定气相中的CO2和硫化物,而且对煤气化过程也表现出较好的催化作用。反应温度600℃,压力为25MPa的条件下,与未加Ca(OH)2相比,Ca/C摩尔比为0.45时,气体中CO2的体积分数由50.7%降至1.0%,趋于完全固定;硫化物浓度由10 878mg/m3降至807mg/m3;H2的体积分数由32.4%增至73.3%。Ca(OH)2对煤气化的催化作用在高温下更加明显。 相似文献

The present paper aims to make the energy saving potential provided by waste recycling in Brazil evident by pointing out more specifically the benefits regarding climate change mitigation. In this case, based on the energy saved due to the recycling process of an exogenous amount of waste, we have built two scenarios in order to show the potential for indirectly avoiding CO2 emissions in the country as a result of the recycling process. According to the scenario, 1 Mt and 3.5 Mt of CO2, respectively, would be avoided per year due to solid waste recycling. The international context for greenhouse gas emissions reduction, such as the United Nations Framework Convention on Climate Change and its Kyoto Protocol has been taken into account. 相似文献

The emission of waste in an economy, including landfill, is to a large extent determined by its patterns of technology, institutions,
and lifestyle. A mathematical model (the waste input–output model) is presented that gives a simple analytical representation
of this interdependence. The model was used to evaluate the effects of alternative waste disposal and recycling options on
the levels of industrial production, landfill consumption, and the emission of carbon dioxide, and also to analyze the overall
dependence on landfill of individual industries. It was found that a systematic combination of the options could be effective
in reducing the overall landfill consumption and carbon dioxide emission.

The incineration of food waste water in conjunction with the domestic waste is getting attention as a food waste water treatment method, due to its low treatment cost and high efficiency. Many studies verified that the ammonia in the food waste water served as a reducing agent to suppress the generation of NOx when the food waste water was injected and incinerated. However, they have not revealed the correlation between the change in the concentration of the CO and NOx by the influence of the solid matters contained in the food waste water on the incineration of the wastes. The purpose of this study is to determine the optimum amount of the food waste water injected through four nozzles in the primary and secondary incineration chambers and to assess the correlation between the concentration of CO and NOx in accordance with the food waste water injection in each chamber of the incinerator. For the study, four food waste water injection nozzles were installed; two (A and B) at the top of the primary incineration chamber and the other two (C and D) in the secondary incineration chamber. The correlation between the change in the concentration of CO and NOx was studied adjusting the amount of the food waste water injected through the nozzles. From the result, Case II showed the concentration of CO and NOx as 1.8–10 and 14–26 ppm, respectively, while Case I showed that of CO and NOx as 15–30 and 9–18 ppm, respectively. Those levels are well below the Korean emission criteria, 50 ppm for CO and 80 ppm for NOx. Based on the results, it is evident there is a certain trade-off between emission of CO and NOx, and Case II which has relatively low concentration of CO is easier and cheaper to control. 相似文献
