Mathematical Model of Vortex Pyrolysis of Biomass

A mathematical model has been developed for analyzing the steady-state performances of vortex pyrolysis reactors used to convert particles of raw biomass materials (usually small wood chips) into char, tar, and gas. Optimal designs are usually considered to be those that maximize the production of tar. This model and its submodels can be regarded as more highly evolved versions of the model and submodels described in "Mathematical Model of a Direct-Contact Pyrolysis Reactor" (NPO-20069), "Mathematical Model of Pyrolysis of Biomass Particles (NPO-20070), "Generalized Mathematical Model of Pyrolysis of Plant Biomass" (NPO-20068), and "Production of Tar in Pyrolysis of Large Biomass Particles" (NPO-20067), NASA Tech Briefs, Vol. 22, No. 2 (February 1998).
