Abstract

The situation around the globe is changing dramatically. There are many factors political and climate change that are affecting the rate of consumption of fossil fuel, Nowadays the consumption of the fossil fuels have reached a critical level which challenges there existence for the consumption of future generation simultaneously having an adverse effect towards the society and our environment. So here we are focusing our interest towards the economical use of Lignin, which is one of the primary by product from bio refinery and paper, and pulp industry, it is composed of complex aromatic compounds . Thus If we are able to break it to monomeric units then these compounds can be utilized as a source of industrial chemical from an bio refinery , reducing our dependence towards the fossil fuel. Here we have studied the catalytic depolymerisation of lignin using HZSM 5 as our catalyst, under different parameters of temperature, pressure and with different solvent like methanol, ethanol, butanol, i so propanol. A detailed analysis of the products was conducted. We have achieved to produce benzene, xylene, catechol, cresol, phenol and guaiacol via our reaction. Simultaneously maintaining more than 95% conversion in most of the reaction, with minimal amount of char formation.
