Reforma a vapor de acetona sobre catalisadores de Ni e Co/MgAl2O4: efeito das propriedades redox dos reagentes e dos catalisadores nos caminhos de reação
(Universidade Federal de São Carlos, 2014-12-12)
The Steam reforming of Acetone (SRA) reaction was studied on magnesium aluminate (MgAl2O4) supported nickel (Ni) and cobalt (Co) catalysts. The catalysts with 8 wt.% of Ni, Co or Ni-Co were prepared by dry impregnation and ...
Síntese de acil fosfodiésteres por mecanoquímica: uma metodologia de química verde
(Universidade Federal de São Carlos, 2019-08-22)
Green chemistry is very concerned with the sustainability of chemical reactions, where one of the objectives, which in the formulation/remodeling of synthetic routes can replace toxic solvents with solvents of lower toxicity, ...
