Special Issue Information

Dear Colleagues,

This Special Issue of ChemEngineering will aim the publication of original manuscripts and critical reviews dealing with the application of the process development principles both at industrial and laboratory scales. Manuscripts emphasizing highly active catalyst preparation and testing, process design, modeling,  optimization  and their economic efficiency assesment, with the end-goal of producing value added (bio)chemical products will be welcome.

In order to produce value added chemical and biochemical products, an increasing number of processes, involving both homogeneous and heterogeneous catalytic materials, are proposed nowadays in different engineering fields. The development of an industrial process requires extensive laboratory studies, and then an appropriate scale-up to provide a sufficient level of know-how. Manufacturing a catalyst with good activity and selectivity for a specific product plays a crucial role in increasing the economic efficiency of a process, whereas this step requires developing appropriate operating conditions for catalyst synthesis with a strong correlation between these aspects and the chemical structure of the catalyst. Given the global environmental requirements, a special emphasis should be conferred to the use of renewable raw materials as well as the minimization of wastes in the proposed alternatives.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ChemEngineering is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In the present investigation, response surface methodology (RSM) and machine learning (ML) are applied to the biodiesel production process via acid-catalyzed transesterification and esterification of triglyceride (TG). In order to optimize the production of biodiesel from used cooking oil (UCO) in a microwave reactor, these models are also compared. During the process, Box–Behnken design (BBD) and an artificial neural network (ANN) were used to evaluate the effect of the catalyst content (3.0–7.0 wt.%), methanol/UCO mole ratio (12:1–18:1), and irradiation time (5.0–9.0 min). The process conditions were adjusted and developed to predict the highest biodiesel yield using BBD with the RSM approach and an ANN model. With optimal process parameters of 4.94 wt.% catalyst content, 16.76:1 methanol/UCO mole ratio, and 8.13 min of irradiation time, a yield of approximately 98.62% was discovered. The coefficient of determination (R2) for the BBD model was found to be 0.9988, and the correlation coefficient (R) for the ANN model was found to be 0.9994. According to the findings, applying RSM and ANN models is advantageous when optimizing the biodiesel manufacturing process as well as making predictions about it. This renewable and environmentally friendly process has the potential to provide a sustainable route for the synthesis of high-quality biodiesel from waste oil with a low cost and high acid value.
