The copyrolysis of biomass/polyolefin mixture was performed to obtain gaseous hydrocarbons. The difference of the gaseous fractions was analyzed by gas chromatography (GC). The optimum condition for C3-C4 gases production was temperature 410°C, the biomass/polyolefin (in mass) mixtures ratio 1:1. At 410°C, the copyrolysis leaded to the production of more than 30% (in mass) of gases. It should be noted...
The mechanism of sulfur retention by alkali and specific earth metals of corn straw and coal were experimentally investigated using thermogravimetric analyzer (TG) and gas chromatography and mass spectrometer (GC-MS), as well as the effects of different concentration of oxygen on alkali earth metal CaO sulfate. The results show that the existence of alkali metals can catalyze volatile content and...
Biodegradation of Reactive Red 2(RR2) by anaerobic process UASB was investigated under thermophilic condition such as 55 plusmn 1degC. The quasi-steady state of the UASB reactor was achieved after 92 running days when the conditions were as follows: hydraulic retention time (HRT) 12 h, salinity 50000 mg/L, COD 1000 mg/L, RR2 100 mg /L. The removal efficiencies of COD and RR2 were about 20% and 92%,...
The experiment on smoldering gasification in woody biomass has been carried out with a horizontal packed bed. Gas chromatography is employed to analyze the concentration of CH4, H2, CO, CO2 and O2 in gas products of smoldering gasification. The affects of temperature, moisture concentration and air condition on the flammable compositions of gas products are discussed. It is concluded that gas products...
