The chemical synthesis of heterocycles typically requires elevated temperature and acid or base addition to form the desired product. Moreover, these reactions often involve hazardous reagents, which is why biocatalytic routes for heterocycle formation have gained increasing attention. In recent years, several enzymes belonging amidohydrolase superfamily been identified generate via cycloconden...
in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...
Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...
Recent advances in supercomputers and parallel solver techniques have enabled users to run large simulations problems using millions of processors. Techniques for multiphysics nuclear reactor core simulations are under active development in several countries. Most of these techniques require large unstructured meshes that can be hard to generate in a standalone desktop computers because of high...
This study investigates the anaerobic treatability of reactive Red2 in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaerob...
Microbial Degradation and Decolorization of Acid Orange Dye by Anaerobic /Aerobic Sequential Process
This study investigates the anaerobic treatability of Acid orange dye in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaer...
Enzyme catalysis, made tremendous progress over the last years in identification of new enzymes and enzymatic reactivity’s as well optimization existing enzymes. However, performance resulting processes is often still limited, e.g., regard productivity, realized product concentrations stability Different topics (like limited specific activity, unfavourable kinetics or enzyme stability) can be a...
