不同厌氧发酵工艺对煤制氢的影响
INFLUENCE OF DIFFERENT ANAEROBIC FERMENTATION TECHNOLOGIES ON HYDROGEN PRODUCTION FROM COAL
摘要
Abstract
As we know, coal could be transformed into biogenic methane by microbiological action, but biogenic hydrogen production from coal has not yet been reported. This study will constitute an important complement to the coal bed methane bioengineering. Taking coking coal in Shaqu mine as fermentative substrate, taking mine water strains in the same mining area and the white-rot fungus preserved in laboratory as bacterial source, the impact of bio-hydrogen production by different fermentation technology was studied at conditions which temperature is 35 C , initial pH is 6. 5 without illumination and anaerobic environment. The results show that; under the conditions of the experiment, the hydrogen volume fraction could reach to 73. 7%, the hydrogen production rate could achieve 23. 56 mL/g coal; compared to the samples that didn't mix white-rot fungus, the hydrogen production rate of the samples which added the white rot fungus were decreased 1. 5-6 times; other things being equal, hydrogen production could be increased from 0. 44 mL to 466. 34 mL if hydrogen producing bacteria in mine water were enriched for 4 d; compared mixed edentate disodium at the beginning of enrich hydrogen producing bacteria with adding it after enrich strains, the former hydrogen production rate were 2-10 times than the latter. Obviously, more clean energy-hydrogen could be obtained from coal by microbiological action.关键词
