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.

It is crucial to find sustainable and renewable fuel sources because traditional fossil fuels are running out pollution levels rising. In this context, biocrude derived from biomass emerges as a promising alternative, with hydrothermal liquefaction (HTL) playing pivotal role in transformation. HTL's versatility converting wide range of or waste materials into especially notable. Therefore, comprehensive review focused on the latest advancements HTL technology, including its potential process various materials, resulting high yields (up 60–86% different types). The study explored such effects catalysts processes, scalability for commercializing continuous aqueous phase recycling. also integration machine learning optimization, offering insights how these advanced computational techniques can enhance efficiency output quality. subsequent hydrotreatment emerge key technologies utilizing source. This not only highlights current state refining upgrading but stresses need ongoing development domains. presented transformative solution energy sector, alternative while tackling impurities heteroatoms management challenges. concluded by underscoring practical implications advancements, suggesting roadmap future research field.

Global fossil fuel consumption has induced emissions of anthropogenic carbon dioxide (CO2), which emanated global warming. Significant levels CO2 are released continually into the atmosphere from extraction fuels to their processing and combustion for heat power generation including fugitive industries unmanaged waste management practices such as open burning solid wastes. With an increase in population subsequent rise energy demands generation, rate release is at a much faster than its recycling through photosynthesis or fixation, increases net accumulation atmosphere. A large amount emitted various sources plants, vehicles manufacturing industries. Thus, capture plays key role race achieve zero emissions, paving path decarbonized economy. To reduce footprints industrial vehicular attempt mitigate effects warming, several capturing valorization technologies have become increasingly important. Hence, this article gives statistical geographical overview other greenhouse gas based on source sector. The review also describes different mechanisms involved utilization pre-combustion, post-combustion, oxy-fuels technologies, direct air capture, chemical looping gasification, ionic liquids, biological fixation geological capture. discusses captured value-added products clean energy, chemicals materials (carbonates polycarbonates supercritical fluids). This highlights certain progressing some promising techniques.

Abstract The global expansion of the bioenergy industry raises concerns, emphasizing need for careful evaluation and sustainable management. To facilitate this, life cycle assessments beyond greenhouse gas emissions energy balance are essential, along with standardization assessment methodologies to enable meaningful comparisons. Here, we review assessment, chemical aspects, policy implication production. We discuss in terms concepts, methods, impacts, gases, land use, water consumption, bioethanol, biodiesel, biogas, techno-economic analysis. Chemical aspects comprise reaction processes means improve efficiency. Concerning policies, tools, frameworks that encourage production presented. found carbon dioxide removal ranges from 45 99% various processes. also emphasizes importance chemistry advancing a more secure future.

Abstract Owing to the enormous consumption of petroleum products and their environmental polluting nature, attention has been given seeking alternative resources for development sustainable products. Biomass is a renewable source that can be converted variety fuels chemicals by different approaches, which are best replacements traditional petroleum‐derived Pyrolysis process in chemical bonds biomass macromolecules such as cellulose, hemicellulose, lignin, fractured into small molecular intermediates under high pressure, results bio‐oil, biochar, fuel gases desired Of these pyrolysis products, bio‐oil primary product usually contains large amounts oxygen nitrogen compounds hinder its application potential. Catalytic beneficial method reported alter constituents quality upgrade them diverse applications. hydropyrolysis copyrolysis an approaches overcome drawbacks raised toward formation process. Layered double hydroxides (LDH) derived forms well‐known catalytic/catalytic support materials various reactions due superior properties, easy preparation, thermal stability, tuneable acid/base properties. This review summarizes progress utilization as‐synthesized LDH modified mixed metal oxides functionalized/composite active catalysts sources.
