项目摘要

In order to mitigate carbon dioxide emission in the utilization of coal, increase in the thermal efficiency is indispensable. For this purpose, Integrated Coal Gasification Combined Cycle (IGCC) has been proposed. Further increase in the thermal efficiency of IGCC, high temperature gas cleaning is indispensable. This project is aimed at development of efficient absorbent of H_2S in the coal gasification gas from an entrained bed coal gasifier. Ferrites were reported to be a good absorbent of H_2S at an elevated temperature. However, a ferrite produced by dry method exhibited very low surface area and only the surface of the ferrite was utilized as an absorbent. To overcome this, we have developed a new process preparing ferrite at a low temperature in a wet method using an activated carbon as ferrite carrier. The zinc ferrite produced in the presence of an activated carbon exhibited a high surface area. H_2S absorption behavior of this sorbent exhibited excellent performance, where alm … More ost all of Fe and Zn in the ferrite was sulfided at 400 to 600℃. Moreover, effluent gas after absorption by using a fixed bed flow reactor, contained very low H_2S concentration of less than 1 ppm. Such high performance has never been observed with zinc ferrite prepared other methods. Ferrites prepared in the presence of low sulfur coal exhibited similar behavior as that prepared in the presence of activated carbon. Cost of the absorbent with coal would be reduced considerably as compared to the ferrite prepared with activated carbon. Calcium ferrite prepared in the presence of coal also exhibited excellent performance for the absorption of H_2S. Detailed studies on the performance of ferrites were done in order to understand performance of the ferrites. Characteristic feature of the ferrite was elucidated.In addition to H_2S absorbent, SO_2 absorbent in coal combustion was developed with CaO and oyster shell. Oyster shell treated with Yallourn coal at 850℃. Improved SO_2 absorption capacity compared to raw oyster shell was achieved. Less
为了减少煤炭利用过程中的二氧化碳排放,提高热效率是必不可少的。为此,提出了整体煤气化联合循环(IGCC)。要进一步提高IGCC的热效率,高温气体净化必不可少。本项目旨在开发高效脱除气流床煤气中H_2S的脱硫剂。据报道,铁氧体在高温下对H_2S有很好的吸收作用。然而,干法生产的铁氧体具有很小的比表面积,并且只利用铁氧体的表面作为吸收剂。为了克服这一问题,我们开发了一种以活性碳为铁氧体载体的低温湿法制备铁氧体的新工艺。在活性碳存在下生产的锌铁氧体具有较高的比表面积。该脱硫剂具有良好的吸H_2S性能,其中ALM-…铁氧体中的大部分铁和锌在400~600℃时硫化。此外,用固定床流反应器吸收后的废气中含有很低的H_2S浓度,低于1ppm。用其他方法制备的锌铁氧体的性能是前所未有的。在低硫煤存在下制备的铁氧体表现出与在活性碳存在下制备的铁氧体相似的行为。与用活性碳制备铁氧体相比,用煤制备的铁氧体吸附剂的成本将大大降低。在煤存在下制备的铁酸钙对H_2S的吸收也表现出优异的性能。为了了解铁氧体的性能,对铁氧体的性能进行了详细的研究。阐述了铁氧体的特性,以CaO和牡蛎壳为原料开发了燃煤SO2脱硫剂。牡蛎壳在850℃用亚伦煤处理。与生蚝壳相比,提高了对SO2的吸收能力。较少
