Two-stage riser catalytic cracking of heavy oil for maximizing propylene yield (TMP) process proposed by State Key Laboratory of Heavy oil Processing, China University of Petroleum, can remarkably enhance the propylene yield and minimize the dry gas and coke yields, and obtain high-quality light oils (gasoline and diesel). It has been commercialized since 2006. Up to now, three TMP commercial u...

In our previous paper, a new measurement method for the coal adhesion property called “surface tension of semi-coke” was devised. The surface semi-coke sample obtained by heat treatment at 500°C measured as unique property. Conventionally, it has been thought that is dominant under low MF (Gieseler maximum fluidity) condition. Moreover, important effective utilization to develop technique enabl...

The biomass and lipid productivity of Chlorella sp. MTF-15 cultivated using aeration with flue gases from a coke oven, hot stove or power plant in a steel plant of the China Steel Corporation in Taiwan were investigated. Using the flue gas from the coke oven, hot stove or power plant for cultivation, the microalgal strain obtained a maximum specific growth rate and lipid production of (0.827 d(...

_____________________________________________________________ Different catalysts based on Y-zeolite, ZSM-5 and amorphous kaolin were prepared and characterized. The catalytic cracking of 1,3,5-triisopropylbenzene (1,3,5-TIPB), 1,4diisopropylbenzene (1,4-DIPB) and n-dodecane were used to investigate the effect of catalyst nature on the catalytic performance. Cracking the largest molecule (1,3,5...

Petroleum coke is a valuable and potential source for clean energy storage if it could be modified legitimately and facilely. In the present study, porous carbon with high surface area and abundant oxygen-containing groups was prepared from petroleum coke by chemical activation and modification processes. The as-prepared carbon exhibits a high surface area (1129 m(2) · g(-1)) and stable microgr...

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...

Using the same materials for cathode and anode in energy storage devices could greatly simplify technological process reduce device cost significantly. In this paper, we assemble a dual carbon-based Li-ion capacitor with active derived entirely from single precursor, petroleum coke. For anode, coke-derived carbon (PCC) is prepared by simple ball milling carbonization, having massive tap density...

SHAHAB is a PC- based simulator developed by Olefin Research Group (ORG), with the simultaneous simulation of the reactor, the firebox, the convection section and the transfer line exchanger in steam Cracking units. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. Using a rigorous kinetic model, a complete reaction network for rep...

Improving operation performance of blast furnaces is necessary to reduce CO2 emissions and pig iron costs. One the important factors for keeping gas permeability well in furnace. Coke fines affect condition become worse, therefore clarification prediction generation behavior coke are desired.

le but etait de realiser un four pour pouvoir consommer, comme combustible, les debris du coke metallurgique de la siderurgie d'isphahan. ainsi, deux fours ont ete construits; l'un pour chauggage domestigue et l'autre, permettant d'atteindre une temperature plus elevee, pour les unites industrielles
