Abstract Using a newly developed experimental setup, the features and advantages of an autothermal single-casing atmospheric subbituminous coal fluidized bed air-blown gasifier, combining combustion gasification section, mixing dispersed phase (inert material, char) heat exchange between them through annular transfer device, have been revealed. To increase efficiency experimental-computational ...

Kinetics-free equilibrium models can predict the exit gas composition of the biomass gasifier, given the solid composition and the equilibrium temperature, but they cannot be used for reactor design. Hence, there is a need to develop a combined transport and kinetic model which takes into account of the kinetics of homogeneous and heterogeneous chemical reactions, transport of volatiles produce...

Chemical looping gasification (CLG) is a novel dual-fluidized bed technology that allows for the production of high-calorific syngas from various solid feedstocks (e.g., biomass). Solid circulation between two coupled fluidized reactors, serving purpose heat and oxygen transport, key parameter CLG technology, making system hydrodynamics backbone process. This study serves to provide holistic in...

Adsorption and ion exchange are examples of fixed-bed sorption processes that show transient behavior. This means differential equations needed to design them. As a result, numerical methods commonly utilized solve these equations. The solution frequently used in analytical is called the Thomas solution. gave complete adds nonlinear equilibrium relationship depends on second-order reaction kine...
