This paper presents a bibliometric study focused on the research carried out in the last 11 years on biodiesel as an alternative fuel. Tools such as HistCite were used to manage metadata found using the Web of Science search engine, including author names, titles, abstracts, publication dates, document types, addresses and references cited. In addition, the impact factor and H index of the journals they published were taken into account to analyze the reliability of the research. The study showed a tendency to increase over the years, from 76 publications in 2007 to a total of 2017 in 2017, an increase of 185.71%. Likewise, it was concluded, among other things, that of the 1423 documents obtained to carry out the study, 84.7% were scientific articles, being the majority of the works carried out, followed by the revisions that reached 5.8%. And that magazines such as FUEL, ENERGY & FUEL and ENERGY were among those that contributed the most to this research. In addition, it was demonstrated that the countries most interested in this technology are India, USA and Peoples R China, being these the ones with more than 254, 222 and 119 publications respectively.

The theoretical analysis of the thermodynamic cycles and the physical processes that occur in a cyclical way has improved the knowledge needed to improve the energy efficiency and the performance of the energy transfer systems in science and engineering. Power generation, cooling, and heating processes are improved by means of numerical methods to study the thermodynamic changes of flows involved in the energy transfer between mechanical devices coupled in industrial processes. Taking into account the growing concern in the recent years for the developing of the new power production schemes related to the steam or gas flows applied to non-conventional sources like solar radiation, residual heat production, wind energy, and, biomass combustion, this paper proposes a thermodynamic analysis of supercritical carbon dioxide (S – CO2) Brayton cycle considering new alternatives of power generation in order to satisfy the elevated energy demand with the improvement of the physical parameters simulated in the thermodynamic model. The first and the second laws of thermodynamics are computed in the mathematical algorithm applied in order to solve the steady-state of the flow pressure and the heat transferred during the power production under different working conditions. The simple and partial cooling configuration is studied in this research considering the less complex features of the supercritical carbon dioxide cycle with the aim to validate the prediction of the mathematical algorithm applied with MATLAB software and verify the improvement of the thermodynamic configuration proposed in this research. A good agreement has been reached during the numerical validation of the model with an error rate of less than 2 percent between the numerical data analyzed with a computed model.

The reduction of the amount of pollution and toxicity by the manufacture of products has been a topic widely investigated by many international organizations, looking for an answer that help humanity to minimize the environmental impact. The main objective of this paper is to study the literature of Green engineering from 2007 to 2017 using bibliometric techniques for obtaining an overview of the production behavior of publications in this topic. The information was discharged and analyzed using tools such as Web of Science (WOS) and HistCite to get important results of the international contribution developing significant advances in this area. According to the results obtained, USA has been the most important country researching in this subject, providing 36.8% of the total publications. From the 257 publications, 60.9% were journal articles, where the Abstracts of papers of the American Chemical Society was the most relevant journal with 14 papers. Between 2014 and 2017 an important increase in the published production was presented, being 2016 the year with the most papers published with 15.6% of total investigations. In recent years, green engineering has been consider in many process on industries as a key tool to help the control of the greenhouse emissions, reducing the environmental impact providing some steps to achieve goals proposed for 2050 according to the ISO 50001 standard.Introducción.
