This comprehensive review explores recent catalyst advancements for the hydrodeoxygenation (HDO) of aromatic oxygenates derived from lignin, with a specific focus on the selective production of valuable aromatics under moderate reaction conditions. It addresses critical challenges in bio-crude oil upgrading, encompassing issues related to catalyst deactivation from coking, methods to mitigate deactivation, and techniques for catalyst regeneration. The study investigates various oxygenates found in bio-crude oil, such as phenol, guaiacol, anisole, and catechol, elucidating their conversion pathways during HDO. The review emphasizes the paramount importance of selectively generating arenes by directly cleaving C–O bonds while avoiding unwanted ring hydrogenation pathways. A comparative analysis of different bio-crude oil upgrading processes underscores the need to enhance biofuel quality for practical applications. Additionally, the review focuses on catalyst design for HDO. It compares six major catalyst categories, including metal sulfides, transition metals, metal phosphides, nitrides, carbides, and oxides, to provide insights for efficient bio-crude oil upgrading toward sustainable and eco-friendly energy alternatives.

“…Consequently, researching a sustainable and renewable energy source to replace non-renewable fuels has become one of the challenges for our society [1,2]. Among all renewable resources, biomass [4][5][6][7][8] and waste plastic [9] have attracted much attention. Compared to natural fuels, biomass has a good reputation for its abundance and carbon neutrality and can be used to produce valueadded bioenergy and biomaterials [3,8].…”

In the work, the effect of thermal conversion of the propane-butane mixture on the yield of the main products and the effect of transformation with different metals was studied. In the temperature range of 750-800 ℃, compared to the results with the catalyst created for the decomposition process of the propane-butane mixture at high temperatures, a decrease in the total yield of lower molecular unsaturated hydrocarbons, i.e., ethylene, propylene, and butylene, and an increase in the formation of hydrogen solids were observed. However, the conversion rate increased with increasing temperature, and the catalyst developed for propane-butane cracking at high temperatures was higher in the presence of 5%Ni. The transformation of 5%CoO*5%NiO*2%ZrO2*8%Na2SO4 with chromium in the temperature range of 600-750℃ allows to obtain ethylene 5.85-13.41%, propylene 3.56-7.14% and the total yield of lower molecular unsaturated hydrocarbons, i.e. ethylene, propylene and butylene 15.42-31.77%. At the same time, the conversion rate has increased. In this case, its values were much higher in the relatively low process temperature range compared to the results of untransformed 5%CoO*5%NiO*2%ZrO2*8%Na2SO4. In addition, the highest yield of propylene at 750 ℃ was 17.47%, the highest yield of propylene in the presence of untransformed 5%CoO*5%NiO*2%ZrO2*8%Na2SO4 was 16%, and -15.12% as a result of temperature-induced changes. The purpose of the work is to study the effect of transformation of the catalyst with different metals on the rate of decomposition reaction of propane-butane mixture at high temperatures and yield of main products.

“…Santi et al [4] In order for bio-oil to be used as a fuel, its physical and chemical properties need to be improved [5][6]. One method that has been used to improve the quality of bio-oil is the hydrodeoxygenation (HDO) process [7][8], where this process is a way to reduce oxygen under high pressure of hydrogen gas which can be done together to increase the concentration of bio-oil. To speed up the reaction, a catalyst is needed.…”

Oil palm midrib are very abundant waste, especially in the North Sumatra, Indonesia. Lignocellulose contained in oil palm midrib can be used as a source of alternative energy raw materials. The purpose of this research is to produce bio-oil that can reduce the use of fossil fuels. Natural zeolite (ZAS) as a catalyst was activated by mineral acid and calcination with nitrogen gas. Impregnation of Ni and Fe into ZAS followed by calcination and oxidation process to obtained Ni-Fe/ZAS catalyst. The conversion of oil palm midrib powder into cellulose was carried out by delignification process with NaOH and bleaching. Then, the conversion of bio-oil is carried out by pyrolysis using the HDO process. Based on the results of the catalyst characterization and activity test showed that the Ni-Fe/ZAS catalyst had good characteristics and activity. Bio-oil from fiber is dominated by lignin derivatives, meanwhile cellulose bio-oil is dominated by furan derivatives. Hydrodeoxygenation using a Ni-Fe/ZAS catalyst on fiber produced slightly different compounds from bio-oil in HDO without a catalyst, especially in the reduction percentage of phenol area from 52.91% to 39.58%. Meanwhile, in HDO bio-oil from cellulose, there was an increase in the percent area of phenol from 27.45% to 35.59%.
