Vor einigen Wochen kam diese Meldung mal so durch die Ticker gelaufen:"The production of diesel from vegetable oil calls for an efficient solid catalyst to make the process fully ecologically friendly. Here we describe the preparation of such a catalyst from common, inexpensive sugars. This high-performance catalyst, which consists of stable sulphonated amorphous carbon, is recyclable and its activity markedly exceeds that of other solid acid catalysts tested for 'biodiesel' production."
Green chemistryBiodiesel made with sugar catalyst : Nature
Vor einigen Tagen nun wurde stolz verkündet, dass Brandenburg in Deutschland führend in der Herstellung von Biodiesel sei - kein Wunder, wenn man die allgegenwärtig gelben Felder im Frühjahr so betrachtet.
Einfach Flattrn wenn es gefällt - Danke.
