Nanoscience and Microsystems ETDs
The overall objective addressed in this research was to gain a better understanding of how native mixed cultures of phototrophic microorganisms from a saline system may be used for biodiesel production. Laboratory batch reactors were grown under variable temperatures and nitrogen concentrations with original inoculum from a hypersaline pond in central New Mexico. Growth at 40 C° led to lower lipid production, lower nitrate consumption, and less diverse communities than growth at 20° C. All communities were dominated by the cyanobacteria Plectonema except the in second experiment, where they were only 30% of the culture. In a second experiment with …

This paper describes experimental work done towards the search for more profitable and sustainable alternatives regarding biodiesel production, using heterogeneous catalysts instead of the conventional homogenous alkaline catalysts, such as NaOH, KOH or sodium methoxide, for the methanolysis reaction. This experimental work is a first stage on the development and optimization of new solid catalysts, able to produce biodiesel from vegetable oils. The heterogeneous catalytic process has many differences from the currently used in industry homogeneous process. The main advantage is that, it requires lower investment costs, since no need for separation steps of methanol/catalyst, biodiesel/catalyst and glycerine/catalyst. This work …
