着色硫细菌在焦炉煤气-水系统及水煤浆中的脱硫研究

将着色硫细菌置于焦炉煤气-水系统与水煤浆中进行了培养,研究了其脱硫作用。着色硫细菌在焦炉煤气-水系统和水煤浆中生长良好,倍增时间为80 6h。在焦炉煤气-水系统及水煤浆中均具有脱硫作用,脱硫过程中煤粒度起重要作用,在0 074mm煤浆中脱硫率可以达到53 2%。 Chromatium was cultured in coke oven gas (COG) and water system and coal water slurry. The desulfurization of Chromatium was also studied. These bacteria grew very well in the system of COG and water, and also well in coal water slurry. It took 80.6 hours for one generation of Chromatium in the system. The size of coal particle was more important during the process of desulfurization .The ratio of desulfurization was 53.2% when the coal particle was 200 mesh.
