Molecular optimization in fluid catalytic cracking process: cartesian coordinate analysis for enhancing efficiency and quality in crude oil refining

Introduction: In crude oil refining, the Fluid Catalytic Cracking (FCC) process converts crude oil into high-quality petrochemical products. Understanding molecular interactions in FCC is crucial for optimization, efficiency, and quality purposes. This quantitative and descriptive study analyzes Cartesian coordinates of key compounds, employing computational chemistry for this purpose. Methodology: Quantitative and descriptive. Through a literature review, typical chemical compounds feeding into the FCC process were identified, including paraffins, olefins, aromatics, and naphthenes among others. These compounds were processed using computational chemistry to obtain their 3D coordinates, optimizing their molecular geometry to represent the real structure, ensuring reliable data accuracy in subsequent simulations and analysis. Analysis and Discussion of Results: Cartesian coordinates aid in understanding and identifying optimal operating conditions, enhancing the comprehension of molecular interactions in real time and facilitating the prediction of separation behaviors. These coordinates are envisaged to optimize crude oil refining processes in FCC, through modeling and visualization of atomic-level movements and collisions. Conclusions: Optimizing molecular geometry using the appropriate force field is crucial for obtaining precise Cartesian coordinates. These coordinates enable the simulation of molecular interactions at the atomic level, design of more efficient catalysts, and optimization of refining processes. Additionally, real-time monitoring with accurate molecular data could ensure consistent product quality in FCC.

Analysis of the lipophilicity of compounds in the refinery alkylation process upstream using computational chemistry

Introduction: Refinery alkylation is crucial for the production of high-octane gasoline with low emissions, meeting environmental requirements and demands of today's automotive industry. This study provides data obtained by computational chemistry analysis of the chemical compounds in the refinery alkylation process input stream, which is expected to significantly improve fuel quality and process efficiency. Objective: The objective of this study is to analyse the lipophilicity values of chemical compounds in the refinery alkylation process input stream, which are identified through an exhaustive literature search and analysed by computational chemistry using the iLOGP, XLOGP3, MLOGP, WLOGP and SILICOS-IT methods. The aim is to understand how the lipophilicity of these compounds influences their behaviour during this crude oil refining process, in order to improve the efficiency and selectivity of this process. Methodology: In this study, observation, measurement, experimentation and systematic and rigorous interpretation of the results are carried out. By means of analysis and bibliographic search, the compounds present in the input flow to the alkylation process in the refinery are determined. These compounds are processed by computational chemistry to obtain the lipophilicity values of each molecule. Subsequently, these values and their influence on the relevant variables of the refining process are meticulously analysed. Results: Consensus Log Po/w combines computational methods to estimate the Log Po/w of each molecule, improving the accuracy of the predictions. This study focuses on analysing the lipophilicity of compounds in the inlet stream for refinery alkylation. Propylene has the lowest value, while n-pentane has the highest. Lipophilicity ensures the solubility and efficiency of the process. Conclusions: The lipophilic characteristics of compounds in the alkylation feed stream are crucial in crude oil refining. Understanding and predicting lipophilicity can be achieved with computational methods such as iLOGP, XLOGP3, WLOGP, MLOGP and SILICOS-IT. Consensus values of lipophilicity range from 1.35 to 2.45, affecting solubility in organic phases and interaction with catalysts, which influences the efficiency and yield of alkylation in refinery.

Neurodidactic approach to the teaching of physics in the training for medical biophysics higher technicians

Introduction: One of the alternatives for the teaching of physics is the application of knowledge and means which are offered from neurodidactics. This scientific discipline is developed from its own inquiries and from other fields of science. However, there is an arduous road to go in the scientific researches that allow the establishment of the epistemological, theoretical and methodological basis of this emerging discipline, which, particularly in the teaching and learning of physics, the studies are still limited. Objective: is to show an approximation to a neurodidactic approach to the teaching of physics in the short-cycle training program for Medical Biophysics Higher Technicians in the University of Medical Sciences of Matanzas. Methodology: The analytical-synthetic method was used to determine the essential aspects of the scientific results that are related to the research topic. Induction-deduction favored determining regularities from the facto-perceptual and configuring the theoretical aspects that are proposed. The hermeneutic-dialectical was used to interpret the theoretical information and carry out a critical analysis. Results: The theoretical aspects that underpin the neurodidactic approach and the steps that must be taken into account to apply it in the teaching of physics are established. Conclusion: The contributions of the neurodidáctics favor the understanding of the teaching-learning process of physics and constitute a theoretical framework that enables the design of tasks and activities that enhance attention and motivation towards learning.

Introduction: Including students with meningocele in Physical Education classes is a great challenge. This requires the use of inclusive teaching strategies. Objective: Design a teaching strategy for the inclusion of students with meningocele in Physical Education classes. Methodology: The research was in an Educational Unit in Santo Domingo, Ecuador, adopting a pre-experimental design for its development, with a qualitative approach, descriptive and field in nature, supported by theoretical and empirical methods and techniques such as direct observation, interviews and documentary review; all of which facilitated the investigative procedure and the interpretation of results in the 4 phases that included the investigative process. Results: 1. A teaching strategy is implemented based on five dimensions: identification of needs, personalized curricular adaptations, diversified evaluation, adaptation of materials and individualized evaluations, which focused on the development of curricular adaptations and collaborative games. 2. It is possible to contribute to the inclusion process and the comprehensive development of the student under study. Conclusions: The implementation in practice of the proposed teaching strategy showed its feasibility, relevance, and scientific novelty, allowing to facilitate the inclusion process within the Physical Education class and the improvement of the abilities of the student with meningocele, which is highly significant within the context of Inclusive Physical Education.
