Última Glucose isomerization in simulated moving bed reactor by Glucose isomerase BABT Silva,Eduardo Alberto Borges da; Souza,Antônio Augusto Ulson de; Rodrigues,Alírio Egídio; Souza,Selene Maria Arruda Guelli Ulson de. Studies were carried out on the production of high-fructose syrup by Simulated Moving Bed (SMB) technology. A mathematical model and numerical methodology were used to predict the behavior and performance of the simulated moving bed reactors and to verify some important aspects for application of this technology in the isomerization process. The developed algorithm used the strategy that considered equivalences between simulated moving bed reactors and true moving bed reactors. The kinetic parameters of the enzymatic reaction were obtained experimentally using discontinuous reactors by the Lineweaver-Burk technique. Mass transfer effects in the reaction conversion using the immobilized enzyme glucose isomerase were investigated. In the SMB reactive system,...

Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132006000400018 Numerical study of n-pentane separation using adsorption column BABT Silva,Adriano da; Mariani,Viviana Cocco; Souza,Antônio Augusto Ulson de; Souza,Selene Maria de Arruda Guelli Ulson. This work simulated numerically the n-pentane separation of a mixture of iso-pentane, n-pentane and nitrogen, using an adsorption column with zeolite 5A. The mathematical model equations of the mass and heat transfer in the adsorption column are presented, as well as the boundary and initials conditions, beyond some hypotheses and considerations. The Volume Finite Method was used in the discretization of the equations to get the system of algebraic equations and posterior development of the computational algorithm. The numerical results using the Differencing Central (CDS) and Upwind (UDS) interpolations were compared with experimental results found in the literature. The influence of the partial pressure in the adsorption column performance was also... Tipo: Info:eu-repo/semantics/article Palavras-chave: Adsorption column; Mass transfer; Finite volume method.
