Processing of sugarcane cellulose employing atmospheric pressure plasmas

Abstract

In this project we propose the implementation of a new method for selective treatment of lignocellulosic material based on atmospheric-pressure plasmas, which may become an important step towards the industrial production of second generation ethanol from sugarcane. The experiments in laboratory scale and the development of the equipment to produce the plasmas will be carried out at Instituto Tecnológico de Aeronáutica. We will then scale up the process at the Pilot Plant for Processes Development, which is now being projected, at Centro de Ciência e Tecnologia do Bioetanol. From the theoretical point of view, the interaction of the plasma electrons with lignocellulosic material should be better understood and a study on this complex matter will be carried out in three different parts: 1) low-energy electron scattering from alpha-glucose and betha-glucose monomers and dimmers. We expect these results to elucidate the differences in resonant processes responsible for the breakage of the respective (alpha->14) and (betha->4) linkages. This study will be carried out at Centro de Ciência e Tecnologia do Bioetanol and the resonance energies should provide invaluable information for optimizing the plasma-based pretreatment lignocellulosic raw materials; 2) once the resonance states are identified, we plan to study dissociation mechanisms by electron impact with the help of nuclear dynamics simulations, at Universidade Federal do ABC; 3) lignocellulosic material contains a large amount of water. We also propose to investigate micro- and macrosolvation effects through some standard approaches coded in quantum chemistry computational packages. This study will be done at Universidade de São Paulo. (AU)
