a series of x(co, mn)/tio2 catalysts (x=2–12wt.%) containing 25%co and 75%mn were prepared by the co-impregnation method. all prepared catalysts have been tested in fischer-tropsch synthesis for production of c2-c4 olefins. it was found that the catalyst containing 8wt.%(co,mn)/tio2 is an optimal catalyst for production of c2-c4 olefins. the effect of operation conditions such as the h2/co mola...

this paper presents a mathematical model that could assist in measuring, monitoring and controlling tem-perature variation in cold and ‘red-hot’ metal working conditions of machining. a numerical analysis tech-nique of the temperature distribution, based on the theory of complex applied potential, was carried out using the principles of relationship analysis between the paths of heat supply in ...

Under normal conditions, the MicroGrid operates interconnected with the upstream medium voltage network. However, scheduled or forced isolation can take place. In such conditions, the MicroGrid must have the ability to operate stably and autonomously, requiring the development of suitable control strategies in order to enable MicroGrid islanded operation. The MicroGrid power sources can also be...
