Abstract
Currently, the vast majority of synthetic products and chemicals are produced from fossil raw materials due to their abundant supply and relatively low cost. However, the utilization of fossil resources will eventually become unsustainable due to population increases, rising prices, decline of available resources and environmental issues. The growing interest in non-edible feedstock as renewable resource has brought about extensive research on the valorization of wood components in the production of chemicals and fuels during the last decades. Lignin, a main constituent of wood, is the second most abundant resource in nature after cellulose and accounts for about 25 % of the world’s biomass. It is estimated that 70 million tons of lignin is annually processed worldwide from pulp and paper industry alone. Lignin is also the largest renewable source of biopolymer. However, in contrast to cellulose and hemicellulose, lignin has gained less attention and underutilized to its potential with regards to its valorization. Wet oxidation has received increased attention as a potential process for production of carboxylic acids from biomass wastes. The process has the advantage that it is extremely clean as it does not involve the use of any harmful chemical reagent and the final products are carbon dioxide and water when complete oxidation is achieved. The main objective of this study is to investigate the various types of products formed during the partial oxidation of lignin and study the factors influencing the yield and composition of products.
