Catalytic Hydrogen Production from Bioethanol

Biohydrogen Production of Vinasse Derived from Bioethanol Processing Industry Wastewater: A Review

Background: Increasing global consumption of fossil fuels leads to greenhouse gas emissions, climate change and environmental pollution. Agricultural, animal and food industrial waste is one of the main sources of pollution. The bioethanol industry is one of 17 highly polluted industries. In the process of producing bioethanol, vinasse is produced, and so far 22.4 Giga litter of vinasse has bee...

A Novel Study of Upgrading Catalytic Reforming Unit by Improving Catalyst Regeneration Process to Enhance Aromatic Compounds, Hydrogen Production, and Hydrogen Purity

Catalytic reforming is a chemical process utilized in petroleum refineries to convert naphtha, typically having low octane ratings, into high octane liquid products, called reformates, which are components of high octane gasoline. In this study, a mathematical model was developed for simulation of semi-regenerative catalytic reforming unit and the result of the proposed model was compared with ...

Energy optimization of bioethanol production via gasification of switchgrass

In this paper, we address the conceptual design of the bioethanol process from switchgrass via gasification. A superstructure is postulated for optimizing energy use that embeds direct or indirect gasification, followed by steam reforming or partial oxidation. Next, the gas composition is adjusted with membrane-PSA or water gas shift. Membrane separation, absorption with ethanol-amines and PSA ...

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

Effective heterogeneous transition metal glycerolates catalysts for one-step biodiesel production from low grade non-refined Jatropha oil and crude aqueous bioethanol

The utilization of bioethanol as the alcohol source for biodiesel production is more environmentally advantageous over methanol owing to its lower toxicity, lower flammability and its sustainable supply from renewable agricultural resources. However, as the presence of water in crude bioethanol is the critical factor limiting the biodiesel production process, the energy-intensive and costly pur...
