The pyrolysis performances and reaction kinetics of pine needles (PN) were investigated by integrating thermogravimetric analysis, Fourier transform infrared spectroscopy, pyrolysis-gas chromatography/mass spectrometry. average activation energy PN was estimated to be 183.2 kJ/mol Kissinger Akahira Sunose (KAS) 183.8 Flynn Wall Ozawa (FWO), respectively at heating rates 10, 20, 40 °C/min. found...

Lignocellulosic biomass is the potential raw material for production of biofuels through pyrolysis. It an effective technique converting to biofuels. However, biofuel from agricultural residues and woody-based feedstocks shows poor fuel properties due higher oxygen content. Co-pyrolysis a promising process produce high-quality bio-oil by two or more different materials. Forestry, industrial, ou...

The aim of the research presented in this article was to analyse processes source-rock decomposition, including kinetic parameters pyrolysis, relation type organic matter and its maturity. examined source rocks were Menilite shales from several units within Flysch Carpathians (Poland). samples analysed with use thermal methods, Rock-Eval thermogravimetry coupled an FTIR detector. Kinetic determ...

the purposes of this article are studying the effects of oxygen presence on waste wood pyrolysis process in order to produce bio-char. to reach the goal, cubic samples of size 2.5 cm pyrolized at 300 and 400 °c. the surface and center temperatures of samples were measured and their mass losses were calculated from the ratio of pyrolized mass to initial mass of the sample. increase in temperatur...

Charcoal identification and the quantification of its abundance in sedimentary archives is commonly used to reconstruct fire frequency amounts biomass burning. There are, however, limited metrics measure past temperature fuel type (i.e. types plants that comprise load), which are important for fully understanding impact regimes. Here, we expand modern reference dataset charcoal spectra derived ...

NaOH, dolomite and NiCl2 were used as catalysts to examine their effects on co–pyrolysis with waste bicycle tires (WT) engine oil (WEO). The pyrolysis behaviors investigated by thermogravimetric analysis. activation energy of the catalytic main reaction stage was derived Kissinger–Akahira–Sunose (KAS) method under four different heating rates conditions. calculations show that all three can red...

Low-rank coal (LRC) pyrolysis assisted by biomass can realize the clean and efficient conversion utilization of LRC. The gas tar characteristics obtained from co-pyrolysis apple branch (AB) LRC at different stages were studied with TG-FTIR Py-GC/MS. It was found that process could be divided into four stages, weight loss rate AB+LRC 24.03% in second stage (194.60–404.63 °C), lower than calculat...

The co-pyrolysis of waste electrical and electronic equipments (WEEEs) and waste biomass to obtain pyrolysis-oil, a liquid fuel or chemical feedstock, was carried out in the present work. The pyrolysis-oil yield of co-pyrolysis reached 62.3% which was significantly higher than those of pyrolysis of WEEEs and biomass alone (i.e., 53.1% for WEEEs and 46.3% for biomass), suggesting that synergisti...
