8. Biodiesel in Laboratory

11. Trends Broadening of substrate basis: e.g used kitchen oil, fats from waste water treatment (skimmer) Improve purity and stability against decomposition Standardization and quality control of biofuels Car manufacturers optimize the engine performance for operation with biodiesel (stability of materials, lubrication proprties) Biodiesel production: improvements of phase separation, solid catalysts (e.g. acidic modified cabohydrates) Besides biodiesel so called BTL-fuel („Choren-Process“, „SunFuel“) will be available with higher contributions from solid biomass Today: cars operated with compressed natural gas can compete with biodiesel vehicles, they serve a growing market
