Special Issue Information

Dear Colleagues, 

Biofuel is one of the main renewable fuels capable of substituting fossil fuel in power generation and transportation. Although electric vehicles will be the one of the options for the substitution of internal combustion engines, until this substitution is complete, biofuel is an excellent alternative. It is particularly relevant in the mid-term for road transport and in the long-term for rail, marine, and aviation transport as well as electricity generation. Biofuel is a renewable and sustainable energy source made from raw materials and wastes, among other resources. Advanced technologies and processes are employed to produce biofuels, such as transesterification, esterification, pyrolysis, etc. Thus, due to the merits of biodiesel for environmental sustainability, bioenergy technologies and processes play a crucial role in renewable energy development. This Special Issue aims to publish a comprehensive overview and in-depth technical research papers addressing recent progress in biofuel processes and applications. Studies of advanced techniques and methods for biofuel production and biofuel applications are also welcomed. Research involving experimental and numerical studies, review papers, recent developments, and the current state-of-the-art and emerging technologies in this field are highly encouraged.

Biodiesel is one the most sought after alternate fuels in the current global need for sustainable and renewable energy sources due to their lower emissions and no major modification requirement to existing engines. However, the performance and productivity of the biodiesel production process are significantly dependent on the process parameters. In this regard, a novel hybrid genetic programming-gray wolf optimizer approach for the process optimization of biodiesel production is proposed in this paper. For an illustration of the proposed approach, kinematic viscosity is expressed as a symbolic regression metamodel to account for the influence of catalyst concentration, reaction temperature, alcohol-to-oil molar ratio, and reaction time. Then, the genetic programming-based symbolic regression metamodel is used as an objective function by the gray wolf optimizer to optimize the process parameters. The obtained results show that the proposed approach is simple, accurate, and robust. Full article

The constant increase in greenhouse gases in the environment is forcing people to look for different ways to reduce such pollution. One of these ways is the use of biodiesel for road transport. Conventional biodiesel production involves the catalytic triglyceride transesterification process. When using homogeneous two-stage catalysis, it is difficult to purify the resulting product from the by-products formed, and the catalysts cannot be reused. In the case of heterogeneous catalysis, the process costs are increased due to separation and regeneration of the catalysts. To solve these problems of catalytic synthesis, a noncatalytic process has been recently studied that which takes place under supercritical conditions for an alcohol or other acyl receptor. In such biodiesel production, fatty feedstocks and alcohols are used as raw materials, with the synthesis taking place at supercritical conditions for alcohol, i.e., high temperature and pressure, thus making the process quite simple. This paper reviews the results obtained from biodiesel synthesis using a noncatalytic supercritical process for transesterification using both alcohols and carboxylate esters of low molecular weight, evaluating the optimal conditions for these processes and biofuel stability at high temperatures.
