problem of quartz lined fluidized bed reactor

Nuclear thermal rocket - Wikipedia. A nuclear thermal rocket is a proposed spacecraft propulsion technology. In a nuclear thermal rocket a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor, and then expands through a rocket nozzle to create thrust.In this kind of thermal rocket, the nuclear reactor's energy

problem of quartz lined fluidized bed reactor

The experimental data were obtained with two reactors: a 300-W, methane-fired, tubular, quartz-lined reactor for studying homogeneous oxidation reactions and a fixed-bed reactor, also of quartz, for studying heterogeneous reactions. The latter was attached to the exit of the former to provide realistic combustion gases. The fixed-bed reactor

2018-6-19  Fluidized-Bed Reactor As opposed to fixed-bed reactors, fluidized-bed reactors contain their catalyst material in a fluid state. This fluid state can take on many different forms from having the catalyst suspended in an inert liquid, such as mineral oil, to having particles of the catalyst suspended by gas flowing through the reactor. There

Scale-up of bubbling fluidized bed reactors

The scale-up of bubbling fluidized bed reactors to commercial size is a complex and troublesome endeavor. In particular, the proper scale-up of the hydrodynamics and chemical conversion inside the fluidized bed is subject to many eventualities and pitfalls which may drastically deteriorate the reactor's performance and economy.
