This study utilized microwave irradiation to induce torrefaction (mild pyrolysis) of rice husk and sugarcane residues by varying different parameters, including microwave power level, processing time, water content, and particle size of biomass. Proper microwave power levels are suggested to be set between 250 and 300W for the torrefaction of these two agricultural residues. With proper processing...
The fuel characteristics, the combustion profile, and the kinetic study of char that had been pyrolyzed at 300−500 °C were investigated for RH (rice husks), WC (wood chips), and WP (wood pellets). When a higher pyrolysis temperature was used, the calorific value became proportional to the fuel ratio and inversely proportional to that of the volatile matter. The pyrolysis temperature increased, the...
Thermal gravimetric (TG) analysis was conducted to compare the fundamental pyrolytic behaviors between the lignocellulose fermentation residue (LFR) and three other biomass raw materials. It was found that the TG weight loss curve of LFR appeared very close to the curve of acidified alkaline lignin (AAL), but different to the material of dried distillers grains with solubles (DDGS, also a fermentation...
A study of the pyrolysis of methane mixtures in a laboratory reactor, exploring the influence of the bath gas used (N 2 and CO 2 ) and the presence of small amounts of ethane to simulate natural gas, has been carried out at atmospheric pressure and the 1250–1500 K temperature range. Exhaust gaseous species analysis was realized using a gas chromatographic system and total soot was...
The pyrolysis of acetylene-methanol, acetylene-ethanol, acetylene-isopropanol and acetylene-n-butanol mixtures has been studied in a flow reactor in the 975–1475 K temperature range. The purpose of this work is to analyze the effect of each alcohol on soot and gas products coming from the pyrolysis of the mixtures compared to the results observed in the pyrolysis of pure acetylene, taken as a reference...
Pyrolysis of tert-butanol (2.77% tert-butanol in argon) in a laminar plug flow reactor was studied at low pressure and a temperature range of 950–1850 K. More than 20 pyrolysis species were identified by using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS); and their mole fraction profiles versus the pyrolysis temperature were evaluated. A kinetic model including 101...
The thermal decomposition of methyl decanoate (MD) was studied in a bench-scale pyrolysis set-up equipped with a dedicated on-line analysis section including a GC×GC-FID/(TOF-MS). This analysis section enables quantitative and qualitative on-line analyses of the entire reactor effluent with high level of detail including measurement of formaldehyde and water. The reactor temperature was varied from...
Date palm residues are an attractive source of biomass energy since they are renewable, abundantly available and do not compete with food crops. Pyrolysis and combustion may be efficient methods of exploiting energy from these biomass resources. The purpose of this research was to investigate the thermal behavior of date palm biomass in order to evaluate their usefulness for energy production. In...
With the objective to measure coal conversion at realistic operation conditions the Pressurised High Temperature Entrained Flow Reactor (PiTER) is developed. The pyrolysis of Rhenish lignite is studied at temperatures up to 1600 °C and pressures up to 2.5 MPa. At longer residence time (above 1.5 s) volatile yield is 68 wt% and independent of temperature and pressure.Char samples are extracted from...
