Liquefaction of Lignocelluloses as a Promising Alternative to Petrochemicals

Abstract

Current world population is heavily dependent on fossil fuels (petrochemicals) for their energy needs and it is difficult to imagine what would happen to the world when this limited resource has come to the end in one day. Fossil resources are limited, environmentally unfriendly and their prices are liable to change unpredictably and rapidly depending on political and economic situations. It has predicted that if we use this scary limited resource at the current rate of consumption, less than a half century it would come to an end. On the other hand, excessive usage of petrochemicals has created a lot of environmental issuers as well, such as polluted environments in most of the highly congested cities in the world and global warming due to greenhouse effect. Further evaluation of much warmer climates in the world is responsible for the rising of sea levels due to melting of snow etc., It can be expected that in the near future tiny island around the globe would be no longer visible and would sink. Therefore, seeking and developing of alternative and new energy resources as well as lowering of the rate of consumption of petrochemicals are equally vital.
