Bioelectrochemical Enhancement of Biogenic Methane Conversion of Coal

Bioelectrochemical Energy Conversion.

The interaction between photosynthetic microorganisms and an inert electrode material was examined. Cathodic polarization values of platinum-bearing marine algae were obtained over a wide current-density range under both illumination and dark conditions. A potential shift of 0.6 v in the cathodic direction occurred upon illumination at a current density of 4.3 mua/cm(2). Similar photo-induced r...

Estimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine

Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...

Cryogenic Displacement and Accumulation of Biogenic Methane in Frozen Soils

Evidences of highly localized methane fluxes are reported from the Arctic shelf, hot spots of methane emissions in thermokarst lakes, and are believed to evolve to features like Yamal crater on land. The origin of large methane outbursts is problematic. Here we show, that the biogenic methane (δ13C ≤ −71h) which formed before and during soil freezing is presently held in the permafrost. Field a...

Molecular Catalytic Coal Liquid Conversion

In this Quarter, the research was focused continually on the two general tasks: Task 1, molecular organometallic catalysts for hydrogenation and Task 2, organic base catalysts for arene hydrogenation and the hydrotreating of the coal liquids. With regards to Task 1, the [ 1,5-HDRhCl] suffer catalyst system has been investigated in detail to improve its performance. In the presence of CTAB ([CTA...
