Method for treating organic matter and obtaining and refining fuels from said matter

Published online: Jul 26, 2010

Geographical region Europe
Subject Production of fuel
Published date Jun 16, 2010
Title Method for treating organic matter and obtaining and refining fuels from said matter
Patent Application Number EP2196519 A1
Inventor Angulo Lafuente Francisco, Spain
Relevance Method for obtaining and refining fuels by treating organic materials.
Type of claims Publication
Overview This patent discloses a method for processing organic materials to obtain paraffins by microbial treatment, which are further treated to use as a fuel. The microbial treatment is carried out using yeast or bacteria under anaerobic condition. Advantageously, the process results in different combustible materials such as methane, paraffins and fatty acids, alcohols and solid organic material, which are used as an agricultural fertilizer or as a fuel after being dried. The method comprises, A) fermenting the mass at ambient temperature by adding microorganisms for about 5 days, B) heating the mass obtained at a temperature of 50 degree Celcius to 90 degree Celcius after the fermentation for 30-90 min for the extraction of fats, C) filtering the resulting liquid mass, D) extracting the paraffins and fatty acids obtained from the liquid mass produced, E) distilling the resulting mass to obtain alcohols and F) mixing paraffins with the alcohols obtained in the process in the proper proportions.
