Tectonic deformation acts on an indispensable factor affecting the crystalline structure, but its relationship on the evolution mechanism of morphological structure is seldom considered. In this work, the characterization of microcrystalline and morphological structures in the tectonic coal was comprehensively explored using XRD, pore structure analyzers (N2 adsorption and mercury intrusion methods) and micro-CT. The XRD results indicate that the transformation of chemical composition was observ...
The ignition mechanism was studied for a group of gel fuel compositions in a high-temperature oxidizer medium. It was determined how the initial temperature of the fuel influences the ignition characteristics. The gel fuel (oil-filled cryogel) was prepared from an oil emulsion based on the mixture of a combustible liquid and polyvinyl alcohol. The composition of primary oil emulsions was as follows: the aqueous solution of polyvinyl alcohol (5, 10 wt%) + 40–60 vol% of oil + 2 vol% of emulsifier....

This study was carried out with the aim of evaluating the effect of the high pressure on the oxidation kinetics of n-heptane insoluble asphaltenes, obtained from an extra-heavy crude oil. Thermogravimetric analyses were performed under air atmosphere, at different pressures from 0.084 MPa to 7 MPa, and temperatures from 100 °C to 600 °C at different heating ramps of 5 °C·min-1, 10 °C·min-1, and 15 °C·min-1. The effective activation energy and the kinetic parameters were obtained using a first-or...
Anaerobic co-digestion of peanut hull and swine manure was investigated. The interactive effects of total solids percentage (TS%), C/N ratios, inoculum volume percentage (I%) on total biogas production and methane content were evaluated using quadratic regression model and response surface methodology (RSM). The results show, with the assistance of the developed quadratic model, the influence of the three factors on biogas production and methane content were ranked as: TS% > I% > C/N ratio. With...

High oxygen content in lignite increases hydrogen consumption during hydroliquefaction, and simultaneously the produced water decreases hydrogen partial pressure, which negatively affects lignite liquefaction behaviors. Therefore, the liquefaction performances, and oxygen removal behaviors of Xilinhaote (XL) lignite during liquefaction at different temperatures in the presence of Na2CO3 (NC) and FeOOH (FO) were investigated. Results showed that the oxygen contents of liquefaction residues (LRs) ...
