Abstract |
Production of ethanol from lignocellulosic biomass is a promising alternative
source of energy because this world is in need of a low cost, renewable and
sustainable green energy source. Canada is among the top ten producers of wheat
in the world with a capability of producing around 37.52 million tons of wheat
straw per year. Hence, wheat straw could be a potential source of energy. Ozone
was supposed to break down physical and chemical structure of lignin and hence
make cellulose present in wheat straw more accessible for a conversion reaction.
However, it was observed in our experimental work that without pretreatment of
wheat straw, ozone did not produce the expected effects in the reaction with wheat
straw. In spite of conducting the experiments under vigorous conditions only 13 %
of lignin removal was achieved. The proposed technique, which is a strategic use
of water and ozone, has overcome the problem of slow reaction of ozone with
wheat straw. Through this technique, around 90
