Use of sugarcane bagasse ash into silicon products

Electricity and steam are produced from gasification process os 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.
