Non-catalytic biodiesel fuel production with supercritical methanol technologies
Study presents that supercritical methanol has the ability to convert oils/fats consisting of triglycerides and free fatty acids (FFAs) into fatty acid methyl esters through transesterification and methyl esterification, respectively, without any catalyst. This one-step method (Saka process) is simpler process realizing shorter reaction time and higher yield of methyl esters than those of the c...
متن کاملCatalytic Performance and Characterization of Promoted K-La/ZSM-5 Nanocatalyst for Biodiesel Production
The promoted K-La nanocatalysts supported on ZSM-5 zeolite were prepared via wetness impregnation method and tested for biodiesel production from soybean oil. The effects of different weight percentage of La, loading of K as a promoter and calcination conditions on structure and activity of catalyst were investigated. Results showed that the supported catalyst containing 7wt.% of La was pro...
متن کاملCatalytic Behaviour of MnZrOx System for Heterogenous Biodiesel Production
Manganese/zirconium mixed oxides catalysts (MnZrOx), characterized by high Mn loading (up to 50%), along with high specific surface area, have been investigated in the transesterification reaction of sunflower oil. Catalysts were found to be very active by operating at low catalyst/oil ratio (1 wt.%). The high activity was justified on the basis of both the marked basic character of such system...
متن کاملCatalytic applications in the production of biodiesel from vegetable oils.
The predicted shortage of fossil fuels and related environmental concerns have recently attracted significant attention to scientific and technological issues concerning the conversion of biomass into fuels. First-generation biodiesel, obtained from vegetable oils and animal fats by transesterification, relies on commercial technology and rich scientific background, though continuous progress i...
متن کاملSingle Step and Non-Catalytic Process for Formaldehyde Production from Methane using Microchannel Reactor: Theoretical Analysis
Conventionally, methane is reformed into syngas, and subsequently converted into C1-oxygenates (methanol and formaldehyde). A novel option is the catalyst-free single-step conversion of methane to C1-oxygenates. This study presents a comprehensive model of methane partial oxidation to formaldehyde as an intermediate chemical species in methane oxidation process using microreactor. The dependenc...
