Herstellung von Kohlenwasserstoffen aus Tierfett durch thermokatalytisches Spalten

摘要

In Germany 290.000 t of animal fat were produced in 2003.By law resi-dues from rendering plants are excluded from animal feed.Therefore new options of utilisation are required.One way is to con-vert animal residues including animal fat into liquid fuels.This is in agreement with European Community's aim to increase the portion of biogenic fuels up to 5,75 % until 2010.State-of-the-art is the transformation of lipids into alkylesters analog to the pro-duction of bio diesel from rapeseed.A prob-lem is the content of stearic acid in animal fat.After alkylation stearic acid alkylesters precipitate in the range of 10 deg C.This solu-bility behaviour reduces the usability as a fuel in motor pool of rendering plants.
