Energies, Journal Year: 2022, Volume and Issue: 15(7), P. 2383 - 2383

Published: March 24, 2022

Currently, a progressively different approach to the generation of power and production fuels for automotive sector as well domestic applications is being taken. As result, research on feasibility applying renewable energy sources present scenario has been growing, aiming reduce greenhouse gas emissions. Following more than one approach, integration renewables mainly involves utilization biomass-derived raw material combination generated via clean with conventional systems. The aim this review article provide satisfactory overview most recent progress in catalysis hydrogen through sustainable reforming CO2 utilization. In particular, attention focused route that, starting from bioethanol H2 production, leads use produced purposes by means catalytic processes, passing water–gas shift stage. newest approaches reported literature are reviewed, showing that it possible successfully produce “green” hydrogen, which can represent storage technology, its strategy into scenario. Moreover, may be used conversion hydrocarbons, thus giving added value.

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

Journal of Chemical Technology & Biotechnology, Journal Year: 2023, Volume and Issue: 98(9), P. 2077 - 2094

Published: April 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.

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

Environmental Science and Pollution Research, Journal Year: 2021, Volume and Issue: 28(45), P. 64374 - 64393

Published: July 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, Journal Year: 2023, Volume and Issue: 2023, P. 1 - 28

Published: Feb. 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.

Ethanol steam reforming over Ni/ZSM-5 nanosheet for hydrogen production

Chinese Journal of Chemical Engineering, Journal Year: 2024, Volume and Issue: 67, P. 247 - 256

Compared to reforming reactions using hydrocarbons, ethanol steam (ESR) is a sustainable alternative for hydrogen (H2) production since can be produced sustainably biomass. This work explores the catalyst design strategies preparing Ni supported on ZSM-5 zeolite catalysts promote ESR, specifically, two-dimensional nanosheet and conventional crystal were used as carriers two synthesis strategies, i.e., in situ encapsulation wet impregnation method, employed prepare catalysts. Based comparative characterization of catalytic assessments, it was found that combination carrier effective strategy develop promoting H2 via ESR due improved mass transfer (through 2-D structure nanosheet) formation confined small nanoparticles (resulted synthesis). In addition, resulting also showed high dispersion accessibility sites by reactants, being able improve activity stability suppress metal sintering coking during at reaction temperatures. Thus, prepared stable performance with ∼88% conversion ∼65% yield achieved 48-h longevity test 550 °C.
