High concentration and large flow flux of gas drainage from underground coal seams is the precondition of reducing emission and large-scale use of gas.However,t
With the help of Aspen Plus,a two-dimensional unsteady CFD model is developed to simulate the coal gasification process in a fixed bed gasifier.A developed and
High pressure plays a key role in the development of new advanced compounds.The dielectric material CaCu3Ti4O12 were synthesized by solid-state reaction method.
