Department of Chemical Engineering, Biotechnology and Materials

DIQBM

Introduction

Currently the Department is responsible for the Chemical Engineering and Engineering in Biotechnology programs, with the participation of a body of professors characterized by their strong background at a doctorate level and high academic productivity in their respective areas of expertise. The Department also provides postgraduate education at master and doctorate levels in the areas of chemical engineering, biotechnology and materials science.

The Department of Chemical Engineering and Biotechnology and Materials (DIQBM) commenced in the laboratories dedicated to General Chemistry, Analytical Chemistry and Saltpeter processing, all part of the School of Engineering. In 1960, the Center for Chemistry was formed on the basis of the laboratories mentioned. In 1965, the newly formed Department of Chemistry consisted of two areas: Basic Chemistry and Operations and Unit Processes. In 1973, the latter formed an independent department named Chemical Technology. In 1981 both merged; however, it was eventually agreed to separate the areas, becoming two units with clearly defined areas and objectives: the Department of Basic Chemistry and the Department of Chemical Engineering (DIQ). During the second half of the 90's, there was a strong impulse to recruit new academics, which led to the creation of the Biotechnology area and the specialty of Engineering in Biotechnology, in 1996. In view of this, it was renamed the Department of Chemical Engineering and Biotechnology (DIQBT) in 2005.

In parallel, the Department of Materials Science (DCM) began its activities toward the end of 2004, as a result of a merger between the Departments of Basic Chemistry and Materials Engineering. Its mission was to generate fundamental and applied knowledge in the field of Materials Science, and training in Chemistry and Materials Sciences at the basic level for different bachelor degrees.

Recently, in 2017, the DCM merged with the Department of Chemical Engineering and Biotechnology (DIQBT), giving rise to the current Department of Chemical Engineering, Biotechnology and Materials (DIQBM).

The DIQBM contributes increasingly to finding solutions to problems of the national productive sector related to the exploitation and development of natural resources.

Teaching

The Department is responsible for the following programs:

  • Training in Chemistry and Materials Sciences at our Faculty, with an annual average of 800 students within the "Common Plan" (Plan Común) and other specialties in engineering.
  • Minor in Materials Engineering: allows students to better understand the role of materials in modern technology, recognizing fundamental processes that govern their behavior in engineering.
  • Chemical Engineering. A technological-scientific program linked to industrial processes. It is a field of specialization of engineering closely tied to technological innovation through transformation and the enrichment of natural resources.
  • Engineering in Biotechnology: Program associated with the design, evaluation, planning, operation and research of processes and plants that involve the optimal utilization of matter and energy of biological origin (enzymes, bacteria, yeast, microalgae, animal cells, etc.).
  • Master in Engineering Science, mention Chemical Engineering: The program is designed for advanced training in the area of engineering processes, with the choice of a specialization in chemical engineering, biochemistry and biotechnology, processes of polymerization and catalysis, hydro-electrometallurgical processes, and decontamination processes. The program trains graduates to work in academia or in professional research and development activities.
  • PhD in Engineering Sciences, in Chemical Engineering and Biotechnology. Training program for professionals and academics of the highest level in order to independently carry out original research which represent significant contributions to the knowledge in the field of Chemical Engineering and Biotechnology.
  • PhD in Engineering Sciences, mention inMaterialScience:The program objective is to train specialists at the highest scientific and technological level, giving them the capacity to make original contributions to the knowledge and new technologies related to Materials Science.

Research

The Department of Chemical Engineering, Biotechnology and Materials emphasizes research, exploitation and the development of natural resources in such areas as coal, biomass, metallurgical and inorganic salt resources, as well as the biotechnology and polymer industry.

The growth and strengthening of current teaching and research groups opens the way for the future implementation of programs in the modern fields of the synthesis of advanced materials, decontamination and environmental health, biological treatment of water and waste, development of modern technology for the agricultural, fishing and food industries, petrochemicals, etc.
