Hydrocracking has great importance in present day refining due to strict environmental and norms of quality of fuel. In recent years the demand for middle distillate and gasoline has increased tremendously while that of heavy gas has decreased. In the present work we have modeled and then applied five lump scheme to hydrocracker reactor. The first order kinetics was assumed for the conversion i...

Supercritical multi-thermal fluid is an emerging and efficient heat carrier for thermal recovery of heavy oil, but the generation supercritical its feasibility in are rarely discussed. In this paper, flooding experiments were carried out, respectively, fluid. During experiment, temperature pressure reactor sand-pack monitored recorded, generated by reaction was analyzed chromatography, enthalpy...

Abstract We developed an electrocatalytic reduction of (hetero)aryl halides under mild conditions using a proton exchange membrane (PEM) reactor. This approach allows substituting the halogeno groups on aryl rings to protons by water and electron. Taking advantage this transformation, deuterodehalogenation halides, which forms mono‐deuterated (hetero)aryls, was demonstrated heavy as deuterium s...

Due to continuous contamination of groundwater by anthropogenic activities, potable water fetches numerous pollutants such as pathogens, pharmaceuticals, and heavy metals, with these being severe health hazards. The main aim the current study was develop a hybrid unit based on catalytic ozonation filtration process effectively remove contaminants in drinking water. To best our knowledge, study,...

The efforts conducted so far to deal with and evaluate the reliability of passive safety systems (as the thermal-hydraulic passive systems), being implemented in advanced water cooled reactor designs, has aroused an amount of open issues. They should be addressed and conveniently worked out, since it is the major goal of the international community (e.g IAEA) to strive to harmonize the differen...

With the deterioration of the water resources of the world, looking for an economically viable solution to treat wastewater is a challenge, especially in developing countries, where the costs of setting up, operation and maintenance of conventional aerobic treatment plants are difficult to be met with. The various advantages of the anaerobic treatment technologies over the existing aerobic trea...

INTRODUCTION Anaerobic technology have been successful applied for industrial waste water treatment. High reaction rate per unit volume by retaining the biomass in the reactor independently of the incoming waste water flow and concentration. Often high volumetric loading rates in the order of 10 to 40 kg COD/m.d are used. High rate anaerobic biological reactors may be classified into three broa...

The effect of variation in thermal conductivity of light water reactor fuel elements on core response during loss-of-coolant accident scenarios is examined. Initially, a simplified numerical analysis is utilized to determine the time scales associated with dissipation of stored energy from the fuel into the coolant once the fission reaction is stopped. The analysis is then followed by full reac...
