The economic value of bioethylene produced from bioethanol dehydration is remarkable due to its extensive usage in the petrochemical industry. Bioethylene is produced through several routes, such as steam cracking of hydrocarbons from fossil fuel and dehydration of bioethanol, which can be produced through fermentation processes using renewable substrates such as glucose and starch. The rise in oil prices, environmental issues due to toxic emissions caused by the combustion of fossil fuel and depletion of fossil fuel resources have led a demand for an alternative pathway to produce green ethylene. One of the abundant alternative renewable sources for bioethanol production is biomass. Bioethanol produced from biomass is alleged to be a competitive alternative to bioethylene production as it is environmentally friendly and economical. In recent years, many studies have investigated catalysts and new reaction engineering pathways to enhance the bioethylene yield and to lower reaction temperature to drive the technology toward economic feasibility and practicality. This paper critically reviews bioethylene production from bioethanol in the presence of different catalysts, reaction conditions and reactor technologies to achieve a higher yield and selectivity of ethylene. Techno-economic and environmental assessments are performed to further development and commercialization. Finally, key issues and perspectives that require utmost attention to facilitate global penetration of technology are highlighted.

以生物乙醇为原料生产更绿色和可持续的生物乙烯:现状、机遇和前景

生物乙醇脱水制得的生物乙烯因其在石化工业中的广泛应用而具有显着的经济价值。生物乙烯是通过多种途径生产的,例如蒸汽裂解化石燃料中的碳氢化合物和生物乙醇的脱水,可通过发酵过程使用葡萄糖和淀粉等可再生底物生产。油价上涨、化石燃料燃烧引起的有毒排放引起的环境问题以及化石燃料资源的枯竭导致人们需要替代途径来生产绿色乙烯。生物乙醇生产的丰富替代可再生资源之一是生物质。由生物质生产的生物乙醇据称是生物乙烯生产的竞争替代品,因为它既环保又经济。近年来,许多研究研究了催化剂和新的反应工程途径,以提高生物乙烯收率和降低反应温度,以推动该技术向经济可行性和实用性方向发展。本文批判性地回顾了在不同催化剂、反应条件和反应器技术存在下从生物乙醇生产生物乙烯,以实现更高的乙烯收率和选择性。进行技术经济和环境评估以进一步开发和商业化。最后,强调了需要高度关注以促进技术在全球渗透的关键问题和观点。许多研究已经研究了催化剂和新的反应工程途径,以提高生物乙烯产率和降低反应温度,以推动该技术向经济可行性和实用性方向发展。本文批判性地回顾了在不同催化剂、反应条件和反应器技术存在下从生物乙醇生产生物乙烯,以实现更高的乙烯收率和选择性。进行技术经济和环境评估以进一步开发和商业化。最后,强调了需要高度关注以促进技术在全球渗透的关键问题和观点。许多研究已经研究了催化剂和新的反应工程途径,以提高生物乙烯产率和降低反应温度,以推动该技术向经济可行性和实用性方向发展。本文批判性地回顾了在不同催化剂、反应条件和反应器技术存在下从生物乙醇生产生物乙烯,以实现更高的乙烯收率和选择性。进行技术经济和环境评估以进一步开发和商业化。最后,强调了需要高度关注以促进技术在全球渗透的关键问题和观点。反应条件和反应器技术,以实现更高的乙烯收率和选择性。进行技术经济和环境评估以进一步开发和商业化。最后,强调了需要高度关注以促进技术在全球渗透的关键问题和观点。反应条件和反应器技术,以实现更高的乙烯收率和选择性。进行技术经济和环境评估以进一步开发和商业化。最后,强调了需要高度关注以促进技术在全球渗透的关键问题和观点。
