The danger excessive coking pressure poses to the integrity and longevity of coke ovens has been recognized for many years [1-7]. During carbonisation in a coke oven fissures in the coke are generated due to stresses that arise from the differential contraction rates in adjacent layers of coke, which are at different temperatures [8]. Typically they are longitudinal, i.e. perpendicular to the o...

Coke oven, which is a large industrial furnace, is complex in structure. A two-dimensional structure diagram can hardly help one observe the inner structure of a coke oven or master its working principle comprehensively. In order to solve this problem, a complete 3D digital model of a coke oven is generated by assembling the three-dimensional models of coke oven components created with SketchUp...

The formation of carbonaceous species during isobutane dehydrogenation on chromia/zirconia was studied by in situ diffuse reflectance Fourier transform infrared spectroscopy combined with mass spectrometry for on-line product gas analysis. The reactions of the hydroxyl groups of zirconia support with the hydrocarbons and the reduction of the chromates resulted in the formation of adsorbed aceto...

Spatially resolved kinetic data of gallium–platinum SCALMS was captured while elucidating the effect carrier material on coke formation.

With the growing demand for energy and the depletion of conventional crude oil, heavy oil in huge reserve has attracted extensive attention. However, heavy oil cannot be directly refined by existing processes unless they are upgraded due to its complex composition and high concentration of heteroatoms (N, S, Ni, V, etc.). Of the variety of techniques for heavy oil upgrading, supercritical water...
