“…Low‐rank coal is gaining importance because of the decreasing supply of petroleum resources. Recently, many studies on the effective utilization of low‐rank coal via pyrolysis , upgrading of low‐rank coal , co‐combustion of different low‐rank coals , and gasification have been conducted. Among them, catalytic gasification is expected to be one of the most promising low‐rank coal conversion processes, as it produces a large amount of valuable gasses such as H 2 , CO, and CH 4 at low temperatures.…”

SUMMARYSteam co-gasification of iron catalyst-loaded biochar, which was produced by the pyrolysis of woody biomass and Indonesian Adaro subbituminous coal at 800°C, was carried out in this study. The main purpose of this work was to examine the effectiveness of an iron catalyst loaded on biochar for hydrogen (H 2 ) evolution. It was shown that the H 2 evolution for a mixed sample of iron-loaded biochar (20 wt%) and Indonesian Adaro subbituminous coal increased by 20% compared with that for the coal sample with the same amount of iron catalyst and was approximately 1.5 that for the coal sample without the iron catalyst. This increase in the co-gasification H 2 evolution was explained by the chemical form and crystallite size of the iron catalyst.

“…Gas chromatography with mass spectrometric detection (GC/MS) is commonly employed for the analysis of volatile fractions of liquids derived from coal [65,66,[78][79][80][81][82] including also the use of an analytical pyrolyzer as injector [83]. However, other detectors are also employed, such as flame ionization detector (FID) [84][85][86] and atomic emission detector (AED) [87].…”

The chapter presents basic principles of one-dimensional gas chromatography (1D-GC) and comprehensive two-dimensional gas chromatography (GC × GC) related to the main advantages of the two-dimensional technique, as well as its application to the study of organic compounds in liquids derived from coal, mainly through pyrolysis and extraction. It also shows the investigation of compounds contained in bio-oils obtained from biomass through pyrolysis, using GC × GC. Advances in scientific knowledge related to the composition of these complex matrices are shown through different examples of GC × GC analyses, such as the identification of trace compounds that would not be perceived by 1D-GC, organized patterns of elution of structurally related compounds that help their identification, etc. Examples shown make it clear that GC × GC is the technique of choice to elucidate composition of these complex matrices.

“…We note that the co-pyrolysis of industrial distillation residues with biomass remains relatively underexplored. There are fewer than five studies focusing on co-pyrolysis of biomass with the distillation residue from lab-scale bio-oil production [24][25][26][27]. The interaction between industrial distillation residues and biomass remains relatively unexplored.…”

With the tremendous prosperity of industry, more and more hazardous waste is discharged from industrial production processes. Cresol distillation residue is a typical industrial hazardous waste that causes severe pollution without proper treatment. Herein, the co-pyrolysis of rice husk and cresol distillation residue was studied using thermogravimetry–mass spectrometry and kinetic studies. The Coats and Redfern method was employed to calculate the activation energy. The results indicated that the pyrolysis process of cresol distillation residue and RH/CDR (Rice Husk and Cresol Distillation Residue) blends can be divided into four stages and three stages for RH. The introduction of RH not only improved the thermo-stability of cresol distillation residue at a low temperature but also reduced the activation energy of the blends. The activation energy was the lowest when the proportion of rice husk in the blend was 60%. The main gaseous pyrolysis products included CH4, H2O, C2H2, CO2, C3H6 and H2. There existed an unusual combination of synergistic and inhibitive interactions between RH and cresol distillation residue, respectively, within different temperature ranges. The synergistic interaction decreased the reaction’s activation energy, whereas the inhibitive interaction reduced the emission of main gaseous products, such as CH4 and CO2. It was concluded that the addition of RH was conducive to improving the pyrolytic performance of cresol distillation residue and the resource utilization of cresol distillation residue.
