Bioethanol as a potential eco‐friendlier feedstock for catalytic production of fuels and petrochemicals

Journal of Chemical Technology & Biotechnology, Год журнала: 2023, Номер 98(9), С. 2077 - 2094

Опубликована: Апрель 13, 2023

Abstract Bioethanol, synthesized through the valorization of biomass resources, is great importance to many industries. As bioethanol has become more abundant and its price decreased, it an attractive candidate for application as a base material synthesis variety petrochemicals fuel catalysis. In this article, comprehensive review catalytic conversion into hydrocarbons, including olefins gasoline, presented. addition, developments potential research opportunities in field catalysis are provided enhance conversion. According findings study, despite significant progress conversion, further needed address several challenges that will enable improved biofuel chemical production. © 2023 The Authors.

The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, harmful gas emissions, support the sustainability natural resources, including water, minimize amount in landfills, thus reducing environmental degradation. In this paper, wastes biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, bio-oil is reviewed, with special emphasis primary secondary residues as substrates. Some novel approaches are mentioned that offer opportunities to increase efficiency valorization, e.g., hybrid systems. addition physical, chemical, biological pretreatment waste, some combined methods mitigate negative effects various recalcitrant processing (alkali-assisted thermal pretreatment, hydrolysis alkali bioaugmentation) evaluated. addition, production volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, selected platform chemicals from described. Finally, potential uses recovered products discussed.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 11, 2025

Abstract The catalytic conversion of bioethanol to ethylene (C 2 H 4 ) and acetylene offers a transformative approach sustainable production two industrial cornerstones for organic compound polymer syntheses, thereby offering significant economic environmental advantages. In contrast, current methods the synthesis these C hydrocarbons rely on energy‐ carbon‐intensive processes that require high temperatures pressures. present work addresses limitations with novel, low‐energy, bioethanol‐conversion strategy operating at room temperature ambient pressure using sono‐piezo‐photocatalysts. A novel heterostructure graphene oxide fragments (GO) sodium bismuth titanate (NBT) within core‐shell microstructure achieved outstanding rates 134.1 55.5 µmol/g/h, respectively. mechanism is driven by (1) bubble collapse during ultrasound irradiation, generating localized (≈4000 K) pressures (≈100 MPa), (2) piezo‐photocatalytic tuning GO/NBT enhanced charge separation transfer. DFT simulations revealed detailed sono‐piezo‐photocatalytic pathways, showing reductions in energy barriers (22.0 kcal mol −1 (48.0 formation. These findings emphasize critical role catalyst cleaving both C─H C─O bonds effectively, leading desired product

Environmental and economic analysis of bioethanol production from sugarcane molasses and agave juice

Environmental Science and Pollution Research, Год журнала: 2021, Номер 28(45), С. 64374 - 64393

Опубликована: Июль 24, 2021

In this article, sugarcane molasses and agave juice were compared as potential feedstocks for producing bioethanol in Mexico terms of their environmental impact economic factors. Life cycle assessment (LCA) using SimaPro was carried out to calculate impacts by a cradle-to-gate approach. A preliminary analysis performed determine the feasibility studied options. Also, capital goods costs obtained Aspen Plus economy package. Moreover, sensitivity involved compare viability from juice. LCA results revealed that cultivation fermentation most harmful stages when juice, respectively. Furthermore, it derived rather than molasses, had more benefits. This ascribed lower consumption rate fertilizers, pesticides, emissions given off former. Regarding financial aspects, showed not economically viable grid energy alone used. However, if power is partially replaced with renewable energy, becomes feasible, suitable feedstock.

Catalytic Conversion of Low Alcohol to Hydrocarbons: Challenges, Prospects, and Future Work Considerations

International Journal of Energy Research, Год журнала: 2023, Номер 2023, С. 1 - 28

Опубликована: Фев. 4, 2023

Energy sources will contribute enormously to global economic development in the coming years. Global energy sectors mainly depend on fossil fuels, which greenhouse gas emissions. With threat of declining oil supplies and need reduce CO2 emissions, viable substitutes for fuels is high priority list. Currently, there an increased focus using low alcohols as petrochemicals. Catalytic conversion a approach upgrading value-added chemicals. This review study shows that optimal catalyst modification improves catalytic performance volarization bioethanol. Heterogeneous catalysts are widely used bioethanol due their activity. However, further studies needed address challenges limited selectivity, deactivation, recovery, regeneration improved biofuel production.
