Continuous Photo-Oxidation in a Vortex Reactor: Efficient .

We report the construction and use of a vortex reactor which uses a rapidly rotating cylinder to generate Taylor vortices for continuous flow thermal and photochemical reactions. The reactor is designed to operate under conditions required for vortex generation. The flow pattern of the vortices has been represented using computational fluid dynamics, and the presence of the vortices can be .

All five stages may be used for reaction or, alternately, the P-l slurry feed may be diverted around the first two stages of R-l to effectively yield a three-stage reactor. Each reaction stage is a continuous flow stirred tank reactor in which agitation is achieved by means of a variable speed mixer and a slurry recirculator.

Jan 22, 2004 · Naturally, the field of chemical reaction engineering, which features the proverbial continuous, stirred tank reactor, is the first to enter the discussion. In dealing with steady states of a continuous, stirred tank reactor, the issue of primary interest is that of multiplicity of solutions of the algebraic equations.

US20170284294A1 - Oxy-fuel combustion system having .

Experimental and numerical investigations on an atmospheric diffusion oxy-combustion flame in a gas turbine model combustor are conducted. The combustor is fuelled with CH 4 CH4 and a mixture of CO 2 and O 2 as oxidizer. The stability of the oxy-combustion flame is affected when the operating percentage of oxygen in the oxidizer mixture is reduced below 25%.

Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be energy independent.
