BACKGROUND
Biofilters can be used to eliminate different gaseous pollutants including alcohols (e.g. methanol, ethanol) and methane (CH4) individually or in a mixture. In this regard, the biofilter adaptability to feed composition variation is an industrial requisite. Inlet gas composition changes also give a better insight about carbon input and end‐points in biofilters. In this study, the gradual...
In order to solve the problem of lower permeability of coal seam and improve the effective of under ground coal gasification, it has been studied on how low-carbon alcohol solution acts in coal, and on coal permeability in different low-carbon alcohol solutions like methanol, ethanol and isopropanol. The result shows that some organic substance has been extracted from coal under the effects of coal...
This passage took soil samples from Chaohu wetland at 1.5 m buried depth. Then isolated the dominant bacteria and studied its denitrification activity under the condition of different carbon sources (methanol, ethanol and acetic acid) and C/N (3:1, 5:1, 10:1). The results suggested: (1) the nitrate removal rate of isolated strain reached 90% (named as D9); (2) under the condition of C:N was 1:1, acetic...
Here we present a novel signal processing technique for a square wave thermally-modulated carbon black/polymer composite chemoresistor. The technique consists of only two mathematical operations: summing the off-transient and on-transient conductance signals; and subtracting the steady-state conductance signal. A single carbon black/polyvinylpyrrolidone composite chemo -resistor was fabricated and...
