Lignin is a promising alternative to traditional fossil resources for producing biofuels due its aromaticity and renewability. Pyrolysis an efficient technology convert lignin valuable chemicals, which beneficial improving valorization. In this review, pyrolytic behaviors of various were included, as well the mechanism consisting initial, primary, charring stages also introduced. Several parallel reactions, such demethoxylation, demethylation, decarboxylation, decarbonylation side chains form light gases, major structure decomposition generate phenolic compounds, polymerization active intermediates yield char, can be observed through whole pyrolysis process. parameters, temperature, time, type, functional groups (hydroxyl, methoxy), investigated figure out their effects on pyrolysis. On other hand, zeolite-driven catalytic co-pyrolysis with hydrogen-rich co-feedings introduced process efficiency produce more aromatic hydrocarbons (AHs). During process, compounds and/or AHs produced, showing applications in biochemical biofuel additives. Finally, some challenges future perspectives have been discussed.

Abstract The current energy crisis, depletion of fossil fuels, and global climate change have made it imperative to find alternative sources that are both economically sustainable environmentally friendly. Here we review various pathways for converting biomass into bioenergy biochar their applications in producing electricity, biodiesel, biohydrogen. Biomass can be converted biofuels using different methods, including biochemical thermochemical conversion methods. Determining which approach is best relies on the type involved, desired final product, whether or not sustainable. Biochemical methods currently most widely used from biomass, accounting approximately 80% all produced worldwide. Ethanol biodiesel prevalent via processes. Thermochemical less than conversion, 20% Bio-oil syngas, commonly manufactured wood chips, agricultural waste, municipal solid major by conversion. Biofuels potential displace up 27% world's transportation fuel 2050, could result a reduction greenhouse gas emissions 3.7 billion metric tons per year. Biochar yield high ranging 32.8% 97.75%, also serve as an anode, cathode, catalyst microbial cells with maximum power density 4346 mW/m 2 . plays role catalytic methane decomposition dry reforming, hydrogen rates 13.4% 95.7%. increase 220.3%.

The thermochemical conversion of biomass is potentially vital to meeting global demand for sustainable transport fuels so besides combustion; torrefaction, liquefaction, pyrolysis and gasification are reviewed. merits demerits these processes examples industrial applications evaluated, two promising avenues future development identified. upgrading via processing will depend on sector coupling, both within the energy with sectors such as food production. Owing environmental constraints need maintain production, availability traditional feedstocks biofuels, corn, be limited in future. Now given ambitious targets aviation fuel – a higher quality reserving appropriate necessary. Such policy would open opportunities commercial production liquid liquefaction pyrolysis. second avenue opportunity links fact that form wooden pellets has established itself an essential fuel. In UK elsewhere, it already contributing decarbonisation electricity grids. So worldwide, positive combustion, aided where by envisaged increasingly crucial abatement greenhouse gas emissions. Alongside battery storage pumped hydroelectric storage, contribution processes, tackling problem arising from intermittent nature wind solar been clarified first time.

This review provides insights into the current research on pyrolytic bio-oil obtained from different feedstock regarding upgrading techniques and applications such as energy, fuels, chemicals, carbon materials. Raw is not appropriate for transportation ignition due to undesired properties; therefore, several challenges have been reported its suitable market application. For liquid biofuel production, thermochemical pathways, particularly hydrogenation deoxygenation, must be carried out, chemical solvents are mostly used via physical separation. The main issues related downstream processes with environmental economic assessment also covered. analysis indicates that major bottlenecks commercial of upgraded initial stage (upgrading techniques), high production costs, pilot scale production. Finally, future directions addressed improvement upgrading.

The pyrolysis of lignocellulosic biomass is a promising technology for obtaining renewable chemicals and fuels to replace fossil-based products. However, due the complexity lignin, cellulose hemicellulose molecules, large variety compounds are often formed, making commercial implementation difficult. use catalyst during reactions has been recognized as one major improvements in pyrolysis, allowing production selected compounds. Moreover, number available catalysts opens up wide range possibilities controlling reaction network. Zeolites, hierarchical zeolites, alkali alkaline earth oxides, transition metals carbonaceous materials, among others, have investigated biomasses. In addition, bifunctional play role well addition plastics hydrogen donors. This review aims present discuss detail state-of-the-art catalytic focusing on relationships between properties obtained A guideline selecting also provided.
