Cinética da produção de butenos a partir de butanol empregando catalisadores ácidos
(Universidade Federal de Santa Maria, 2017-12-01)
to environmental requirements, new producing routes have been pursued and the butanol
dehydration reaction is one of the most promising. HZSM-5 zeolites and -alumina acid
catalysts were synthesized at different conditions ...
Avaliação da interesterificação catalítica de óleo de macaúba com acetato de metila
(Universidade Federal de Santa Maria, 2017-01-27)
The world concern about the increasing of energy demand, depletion of fossil fuel reserves and global warming aroused interest in biodiesel production. Commonly produced through basic homogeneous transesterification, the ...
Modelagem cinética da produção de biodiesel em estado supercrítico com catalisador heterogêneo
(Universidade Federal de Santa Maria, 2018-02-26)
The main objective of this study was to develop a kinetic model for catalytic supercritical reaction with methyl acetate to produce fatty acid methyl esters. Reaction models and estimated kinetic parameters were proposed ...
