“…In the HDO process, catalysts enhance hydrogenation and deoxygenation reactions, which indicates that the reactions occur on the active metallic sites, with acidic sites [ 20 ]. Therefore, HDO method is more advantageous and comprehensive than other methods [ 13 ]. The reactions occurring during HDO are given in Figure 2 .…”

“…Recently, studies in the field of improving the thermal value and thus its potential use as a fuel by removing the high oxygen content of biooil with the HDO method have increased significantly. HDO; in the presence of a catalyst, in a hydrogen atmosphere, and partially at elevated temperatures (200–400 °C), including reactions such as deoxygenation (C-O bond breaking), hydrogenation (hydrogenation of the C = O bond and aromatic ring), hydrogenolysis, hydrocracking, decarboxylation and dehydration, and thus, it is a critical method that makes it possible to obtain hydrocarbons from oxygenated compounds [ 13 ]. The type of pyrolysis oil produced determines the optimal HDO operation conditions.…”

The development of new fuel sources to replace nonrenewable fossil fuels has received substantial attention due to the ongoing demand for fossil fuels. Biomass and raw waste materials are crucial sources to produce suitable alternative fuels instead of nonrenewable fuels and offer a greener approach. Therefore, improving the fuel properties of biooils produced from the thermochemical conversion of biomass and raw waste materials is critical as it is used as an alternative to nonrenewable fuel. Developing an economical and eco-friendly method to produce sustainable and renewable oil by improving biooil containing large amounts of phenolic compounds has become imperative. One of the most intriguing and promising technologies for refining biooil to produce renewable fuels of comparable quality to conventional fossil fuels is the hydrodeoxygenation (HDO)-based process for converting biooil to renewable fuels. This method is almost one of the best improving methods described in the literature. At this point, it is of great importance that the HDO process is carried out catalytically. Carbon materials are preferred for both designing catalysts for HDO and supporting metal nanoparticles by providing chemically inert surfaces and tunable functional groups, high surface area and active sites. The HDO of biomass and raw waste materials has significantly advanced thanks to carbon-based catalysts. In this review, the effect of the surface character and catalytic ability of the carbon support, especially prepared by the green synthesis technique, on the HDO reaction during biooil improvement is discussed. Moreover, HDO reaction parameters and recent studies have been investigated in depth. Thus, green carbon catalysts’ role in clean fuel production via the HDO process has been clarified.
