*5.2.6 Hydrodeoxygenation*

Hydrodeoxygenation is a degradation reaction that gives rise to aromatics with low oxygen content. In hydrodeoxygenation, under strict temperature and pressure using a catalyst, the lignin can be converted into benzene, cycloalkanes and hydrogenated bio-oil as a fuel [26]. A list of lignin base products synthesized through different reaction process are given below in **Table 3**.

The high abundance and availability of lignin has a great market potential for industrial use. In future the efficient utilization of the isolation process and chemical conversion reaction with new technologies may have significant contributions

for chemicals, materials and fuels from raw lignocellulosic biomass. The successful application of novel process will build a sustainable route in future bioeconomy. In brief the lignin can be used to be converted through the reactions described in to many chemicals products. The lignin has valuable raw materials for several applications. The potential products from lignin for the market are
