• Abstract:

  Electricity and steam are produced

  from gasification process of sugarcane

  bagasse, a residue from alcohol, sugar and

  molasses production. The fly ash produces from

  gasification process are collected frequently

  by water spray gas filter in chimmeys which

  is added to ash from boiler and bottom and

  afterwards it is very often discarded on soil which

  causes its degradation. The ash composition

  indicates a high concentration of quartz and

  charcoal powder. It is proposed a method which

  employing an alumina high temperature reactor

  to transform into silicon products. The heat

  source applied was microwaves in a resonant

  cavity, using a commercial microwave oven.

  It was characterized the regions of standing

  waves in the oven, in order to that the reactor

  could be placed in the most favorable position

  for heating. So far, it was possible to synthesize

  cristobalite, silicon carbide and metallic silicon.

  A new study in order to obtain other products

  may be conducted from different conditions and

  gases
