Köhler/Rögnitz Maschinenteile 1ental setup at 60 °C. Dealumination was found in the alkali leaching calcined catalysts. It was found significant effect on the physical structure and chemical composition of the catalysts. The alkali leached modified mordenite processed transesterification gave the highest methyl ester yield 95.14% with NaOH loading (20% by wt) of in 3 h.

,Reib- und formschlüssige Verbindungen,ation is a very common method to produce biodiesel from raw oil. Other three methods of production of biodiesel are: Direct use and blending of raw oils, micro-emulsion and thermal cracking. The study deals with heterogeneous catalyst based transesterification reaction for conversion of raw WCO into

Köhler/Rögnitz Maschinenteile 1synthesis which can occur only in the presence of sunlight. Thus solar energy is the main driving force behind the production of bioenergy. A major concern that needs to be tackled especially in developing countries is energy poverty wherein 1.4 billion people in rural areas are still lacking access
