Abstract:
Driven by the growing energy crisis and environmental concerns regarding the utilization of fossil fuels, biomass liquefaction has emerged as a highly promising technology for the production of renewable energy and value-added chemicals. However, due to the high oxygen content of biomass materials, biocrude oil produced from liquefaction processes often contains substantial oxygenated compounds, posing challenges for direct downstream applications. Catalytic hydrodeoxygenation (HDO) upgrading with hydrogen donors is crucial for improving the quality and applicability of biomass-derived fuels a

Abstract:

 Resource scarcity and increasing climate change have brought attention to the need for sustainable and renewable resources. Biomass is an earth-rich material with great potential as a feedstock for alternative fuels and chemicals. In order to utilize biomass efficiently, such biopolymers must be depolymerized and converted into key structural units and/or target products, and biological or chemical catalysts are often used for fast and energy-efficient reactions. This paper presents recent advances in the catalytic conversion of biomass into biofuels and value-added products. Hydrodeoxy

Abstract:
Bio-oil emulsions were stabilized using coconut shell coke, modified amphiphilic graphene oxide, and hydrophobic nano-fumed silica as solid emulsifiers. The effects of different particles on the stability of bio-oil emulsions were discussed. Over 21 days, the average droplet size of raw bio-oil increased by 64.78%, while that of bio-oil Pickering emulsion stabilized by three particles only changed within 20%. The bio-oil Pickering emulsion stabilized by Ni/SiO2 was then used for catalytic hydrodeoxygenation. It was found that the bio-oil undergoes polymerization during catalytic hydrogenation.

Abstract:
Catalytic hydrodeoxygenation (HDO), is an effective process to convert oxygenated compounds to hydrocarbons. This process is widely used for improving the negative properties of biomass-derived pyrolysis oils (bio-oils) such as high acidity, poor stability, and low heating value. During this process oxygen is removed from the bio-oil in the form of water, thus the liquid product of HDO process consists of aqueous phase and hydrocarbon phase that can be easily separated. Synthesis of efficient HDO catalyst has been a major challenge in the field of bio-oil upgrading. Red mud, which is an alkali

The upgrading of the Norwegian spruce derived bio-oil was carried out in a batch reactor with conditions of 50 bar H2 (cold) and 3 to 13 hr of batch time at 175 to 250 ℃. The emphasis was given on the effect of operating conditions on the hydrodeoxygenation (HDO) performance of unsupported NiMo nano sulphide catalysts. It is found that the degree of deoxygenation of the bio-oil increases and that of hydrogenation of the upgraded products declines with increasing the reaction temperature.

Abstract:
Lignin is an important component of biomass accounting for up to 30% by weight but up to 40% of the total energy content of the plant. As the push towards alternative fuels develops, more and more amounts of lignin will be gathered and used predominately as low grade boiler fuel to run primary processes. We argue there is usefulness in the conversion of lignin into value added specialty chemicals and fuels. In this work, a new approach for hydrodeoxygenation of lignin model compounds using platinum as the catalyst and organic solvent as the reaction medium was conducted, and the results were c
