Abstract
The present manuscript represents the projection of laboratory experiments in a theoretical reactor projected for the production of biodiesel. The objectives of this project were: production of biodiesel in less time; to reduce the energy consumption into the production of biodiesel; Non-dependence of the reaction kinetics from the reaction's temperature and high conversion rates of raw material into the final product with transesterification reactions performed at stoichiometric limits. The results indicate that the use of a single reaction vessel to perform several stages of production without the transfer of the total mass of fuel fluid between several vessels reduces the total production time. The reaction time was also optimized with the use of an appropriate monitoring system. Performing the reactions near the stoichiometric limits reduced the refining time of the final product, as there are fewer raw materials to be removed from the final product. Monitoring of the reaction with real-time LASER spectroscopy allowed initiating the reaction at room temperature and increasing the supply of energy (heat) throughout the reaction, reducing the energy consumption during the reaction, and the moment of chemical balance was detected with the monitoring system.
PALEOFACIAL CHARACTERISTIC OF UPPER PART OF THE POKURSK SUITE WITHIN THE PURSKY DEFLECTION
In recent decades, there is a tendency of increasing the share of deposits of hydrocarbons, characterized by a complex geological structure. Solving geological problems for this type of geo object requires a comprehensiv...
CHEMICAL AND PHYSICOCHEMICAL CHANGES WITH SUCCESSIVE APPLICATIONS OF RAW DOMESTIC SEWAGE AS A FINAL DISPOSAL ALTERNATIVE OF FORAGE CULTIVATION
Considering the significant expenses with fertilizer and irrigation, the use of wastewater in fertirrigation has been studied as an alternative, since it can supply part of the water demand and provide nutrients to the p...
