Obtaining kinetic data and criteria to avoid mass and energy transfer problems with heterogeneous catalysts. Mundo nano [online]. 2021, vol.14, n.26, 00006.  Epub 03-Mar-2021.

This article discusses the importance of kinetic analyses. The mathematical function of the chemical reaction rate expression (-RA) is introduced, including the expression used in the presence of a catalyst and the functionality of (-RA) with temperature and concentration. Several rate expressions such as power law expressions, theoretical expressions, and LHHW equations are described. It also revises typical reactors used in the laboratory and describes the criteria that can be used to disdain the mass and energy transfer problems commonly presented in catalytic assessments.

Palavras-chave : chemical reaction rate; catalytic activity; power law expressions; LHHW equations; types of laboratory reactors; mass and energy transfer phenomena.
