Special Issue Information

Dear Colleagues,

Alternative and renewable energy sources already play a very decisive role on the development of human society, thus contributing to fulfill the increasing energy demands from both industrialized and under development countries, as well as its economic needs, which must comply to a decarbonized economy, therefore decreasing the energy impact on the global environment. Among these alternative energy sources, fuels such as biodiesel, is a good example of how the previous design could be achieved, as this fuel can be obtained from renewable sources, used in applications such as transportation systems, electricity generation, fuel conversion and even for electricity storage, with reduced impact on air emissions.

Although a great deal of research has been done, and important advances have been reached, in the last years, there is still need for increasing research, particularly in further development of new approaches, regarding the use of advanced catalysis and properties evaluation during biodiesel production.

Therefore, for this Special Issue we invite papers on new and innovative technical developments or approaches, reviews, case studies, as well as assessment, papers from different disciplines, which are relevant to the optimization of biodiesel production processes.

In an era where sustainability is becoming the main driving force for research and development, supercritical fluids-based techniques are presented as a very efficient alternative technology to conventional extraction, purification, and recrystallization processes. Supercritical antisolvent (SAS) precipitation is a novel technique that can replace liquid antisolvent precipitation techniques. Additionally, through the optimization of precipitation operating conditions, morphology, particle size, and particle size distribution of nanoparticles can be controlled. As an antisolvent, supercritical carbon dioxide (scCO2) is far more sustainable than its conventional liquid counterparts; not only does it have a critical point (304 K and 73.8 bar) on its phase diagram that allows for the precipitation processes to be developed so close to room temperature, but also its recovery and, consequently, the precipitated solute purification stage is considerably simpler. This technique can be used efficiently for preparing nanocatalysts to be used in biodiesel production processes. Full article
