Abstract
Carbon neutral energies and fine chemicals are urgently needed in the context of the accelerating global warming and associated extreme weather events. Here we review the conversion of biomass into fuels and chemical compounds with focus on biomass properties, mechanisms of biomass thermal decomposition, bio-oil composition and generation, reactor types, pyrolytic classifications, pyrolysis of pure biomass components, and pyrolysis of wood. The main biomass components, namely cellulose, hemicellulose and lignin, are determined by the Van Soest protocol. Biomass decomposition can be explained by the one-step global mechanism, independent competitive or parallel reactions, the multi-component mechanism, the Broido-Shafizadeh scheme, the secondary tar cracking model and the Ranzi scheme. Pyrolysis can be classified into slow, intermediate, fast, and flash pyrolysis. Reactors comprise fixed bed-, fluidized bed- and multistage reactors.
期刊介绍：
Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
