Bioaromatic, a Sustainable Biofuel: Production and Potential Applications
摘要
Bioaromatics are organically sourced aromatic compounds largely from renewable sources (raw biomass materials or biomass waste). They are compounds largely produced through two major methods, namely the fermentation of raw plant sugar or biomass waste as well as the thermochemical conversion of biomass waste known as pyrolysis. They find application as a sustainable substitute for the aromatic compounds obtained from distillation products of crude oil, offering environmental advantages over their fossil-based counterparts. Bioaromatics have been become largely acceptable as an alternative to the conventional petroleum-derived aromatics used in industry due to their cheap and widespread raw materials with ecological benefits. This study detailed a comprehensive and a critical survey of sustainable modern methodologies for bioaromatics production through fermentation and catalytic pyrolysis, showcasing their potential applications feedstocks chemical. In recent times bioaromatics, have found applications in production of sustainable fuels, chemical compounds, and polyacrylic materials. Bioaromatics are hydrocarbons that possess a high calorific value and have the potential to serve as viable alternatives to petroleum-derived distillates, which are extensively employed in the production of lubricants, adhesives, and various thin protective coatings. In the process of biomass pyrolysis, catalysts such as zeolites, metal oxides, and acidic or alkaline materials are frequently employed. A survey of literature showed zeolites-based catalysts have unique physicochemical properties (pore structure and acidity), which enhances higher molecular weights cracking into smaller aromatic molecules in the crude bio-oil. Its catalytic properties increase in the yield of aromatic chemicals such as benzene, toluene, and xylene, which are crucial for biobased industry. Fermentation and catalytic pyrolysis of biomass waste to produce bioaromatics is an industrially viable way to shape the future of chemical feedstocks in a sustainable and environmentally satisfying manner. The forthcoming change from a petrochemical to a bio-based industry within the framework of the circular economy is a welcome drive or transition towards a more sustainable future.
