Nowadays, the use of computational tools in classroom is quite habitual and important by making the learning process more constructive and dynamic. The objective of this work is to introduce a support didactic material for use in computational classes of Chemical Reaction Engineering. The development of the work is based on a direct implementation of examples of the well-known Fogler's textbook ''Elements of Chemical Reaction Engineering'' in an equation-based dynamic simulator: EMSO. The problems were implemented in a way to preserve the structure of the problem as described in the textbook. The results are illustrated by graph plots generated in the simulator, allowing comparisons with the results presented in the textbook and detailed analyses for effects of variables in the problem. The problems are easily modified, allowing the student to analyze several possibilities, changing equations and values of variables, for example, and observing the results. ß

-Coal and biomass are energy sources with great potential for use in Brazil. Coal-biomass cogasification enables the combination of the positive characteristics of each fuel, besides leading to a cleaner use of coal. The present study evaluates the potential of co-gasification of binary coal-biomass blends using sources widely available in Brazil. This analysis employs computational simulations using a reliable thermodynamic equilibrium model. Favorable operational conditions at high temperatures are determined in order to obtain gaseous products suitable for energy cogeneration and chemical synthesis. This study shows that blends with biomass ratios of 5% and equivalence ratios ≤ 0.3 lead to high cold gas efficiencies. Suitable gaseous products for chemical synthesis were identified at biomass ratios ≤ 35% and moisture contents ≥ 40%. Formation of undesirable nitrogen and sulfur compounds was also analyzed.
