The present study focuses on the valorisation of winery industry wastes through slow pyrolysis exhausted grape marc (EGM). optimal parameters were firstly identified by small scale experiments carried out using thermogravimetric analysis. Nine temperatures tested and their influence decomposition EGM residue biochar yield was evaluated. Then, production conducted in a pilot plant at three chose...

Underground in situ pyrolysis for oil shale extraction is currently significant; the evolutions microstructure, porosity, and permeability parameters are essential factors evaluating productivity of after pyrolysis. With underground reservoir core, obtained from Jimsar Sag Junggar Basin China, as research object, samples were subjected to treatment at different high temperatures (400°C, 500°C, ...

Studies on the pyrolysis of the synthetic cannabinoid agonist UR-144 ((1-pentyl-1H-indol-3-yl)(2,2,3,3-tetramethylcyclopropyl)methanone) have shown that its major pyrolysis product is a tetramethylcyclopropane ring-opened alkene. Considering that smoking is a common way of ingesting synthetic cannabimimetics, the presence of the metabolites of this pyrolysis product would be expected in biologi...

This paper presents an extensive review of the scientific literature associated with various microwave pyrolysis applications in waste to energy engineering. It was established that microwave-heated pyrolysis processes offer a number of advantages over other processes that use traditional thermal heat sources. In particular, microwave-heated processes show a distinct advantage in providing rapi...

AIEWRACT-The pyrolysis of general biomass materials is modeled via a superposition of cellulose, hcmiccllulosc and lignin kinetics. All three of the primary biomass components arc modeled with multi-slcp kinetics involving both compcte-tivc primary pyrolysis and secondary tar decomposition reactions. Only " typical " (untreated) fccdstocks arc considered at at mosphcric pyrolysis pressures. The...

Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (PyGC/MS), thermogravimetric analyzer coupled with Fourier transform infrared spectrometry, and mass spectrometry (TG-FTIR and TG-MS) techniques. The composition of evolved volatiles from fast pyrolysis of tobacco stem was determined by Py-GC/MS analysis, and the e...

The evolution of the pyrolysis of sewage sludge in a fixed and a fluidized bed was analyzed using a novel measuring technique. This original measuring technique consists of installing the whole reactor over a precision scale, capable of measuring the mass of the complete reactor with enough precision to detect the mass released by the sewage sludge sample during its pyrolysis. The inert conditi...

This paper investigates the effects of three parameters (reaction temperature, feedstock particle size and nitrogen flow rate) towards solid (char) yield from pyrolysis bamboo. Three-factor, three-level Taguchi’s L9 Orthogonal Array was used as experimental design. The char at reaction temperatures 300-500°C, 100-1000 μm, rate 100-300 ml min −1 were investigated. maximum predicted based on sign...

Gas phase pyrolysis of o-hydroxybenzyl alcohol at 750 degrees C gave o-quinonemethide, which, on isolation, formed a mixture of the corresponding dimer and trimer. However, pyrolysis of o-hydroxy-[1-(4-pentenyl)]benzyl alcohol permitted intramolecular trapping of the intermediate o-quinonemethide, giving 3,4-trimethylene-3,4-dihydrobenzochroman. In contrast, gas phase pyrolysis of o-mercaptoben...
