Method for the Production of Biogas from Biomass

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for producing biogas from biomass through fermentation. The key feature is the addition of ethanol, in a concentration between 0.01% and 1.5% by volume relative to the total biomass, into the fermentation reactor. The use of ethanol, especially ethanol-containing solutions or fermentation residues, is intended to boost the overall yield of biogas produced from biomass.

Use CasesContent extracted from patent full text and abstract with AI.

• Enhanced biogas production at wastewater treatment plants processing organic waste.
• Improved biogas yield from agricultural biomass like crop residue or animal manure.
• Industrial biogas facilities seeking higher efficiency from organic feedstocks.
• Small-scale biogas installations on farms or in rural communities wishing to optimize output.

BenefitsContent extracted from patent full text and abstract with AI.

• Increases the total biogas yield from the same amount of biomass.
• Improves the economic viability and efficiency of biogas plants.
• Enables better utilization of waste biomass and ethanol-containing byproducts.
• Offers a simple process enhancement without major equipment changes required.

Patent Abstract

Die Erfindung betrifft ein Verfahren zur fermentativen Erzeugung von Biogas aus Biomasse, wobei Biomasse in einem Fermentierungsreaktor bereit gestellt wird, und wobei man der Biomasse Ethanol in einem Bereich von ≥ 0,01 Vol.-% bis ≤ 1,5 Vol.-%, bezogen auf das Gesamtvolumen der Biomasse im Fermentierungsreaktor, zusetzt, sowie die Verwendung von Ethanol insbesondere Ethanol-haltiger Lösung oder Ethanol-haltigen Gärgutes zur Steigerung der Ausbeute der fermentativen Erzeugung von Biogas aus Biomasse.
