Heterogeneous gas-solid reactions play an important role in a wide variety of engineering problems. Accurate numerical modeling is essential in order to correctly interpret experimental measurements, leading to developing a better understanding and design of industrial scale processes. The exothermic nature of gas-solid reactions results in large concentration and temperature gradients, leading...

  Abstract : In this study, we prepared a LaNi0.3Al0.7O3 perovskite catalyst using a sol-gel related method (with prop ionic acid as a solvent) for use in the methane dry reforming reaction to produce synthesis gas. We defined the catalyst structure on the basis of X-ray diffraction analysis and measurements of the specific surface area and particle size distribution. The mixed oxide structure ...

In the paper, course of post-reaction gas afterburning generated during metallurgical process where reduction metal and semi-metal oxides is performed with use carbon presented. Process waste gases can be an alternative source energy to used in same or converted another. The participation chemical enthalpy total stream 93 %, rest physical enthalpy. study, particular attention was paid proper mi...
