Reduction of NO by CO on Cu/ZrO(2)/Al(2)O(3) catalysts: Characterization and catalytic activities
(ELSEVIER SCI LTD, 2009)
ZrO(2), gamma-Al(2)O(3) and ZrO(2)/gamma-Al(2)O(3)-supported copper catalysts have been prepared, each with three different copper loads (1, 2 and 5 wt%), by the impregnation method. The catalysts were characterized by ...
Chromium(VI) reduction in aqueous medium by means of catalytic membrane reactors
(ELSEVIER LTD, 2016-06-01)
A novel method for catalytic reduction of chromium(VI) to chromium(III) in model and real water is proposed in this work. Hydrogen was used as a reducer. Three different catalytic membrane reactors were prepared and employed ...
Nitrate Reduction of Brines from Water Desalination Plants Employing a Low Metallic Charge Pd, In Catalyst and Formic Acid as Reducing Agent
(Springer, 2018-08-07)
Abstract: Brines from desalination plants lead to adverse environmental impact; therefore, their treatment by catalytic reduction has become a topic of increasing interest. This work aims to apply catalytic reduction to ...
Selective ring opening of decalin with Pt–Ir/Al2O3 catalyst prepared by catalytic reduction
(2011)
The reaction of selective ring opening using alumina supported Pt–Ir catalysts with and without Mg addition was studied. The catalysts were prepared by the method of catalytic reduction, having 1 wt% of
Pt whereas the Ir ...
Chromium(VI) reduction in aqueous medium by means of catalytic membrane reactors
(ELSEVIER LTD, 2018)
Influence of tin addition by redox reaction in different media on the catalytic properties of Pt-Re/Al2O3 naphtha reforming catalysts
(Elsevier Science, 2009-11)
The influence of Sn addition by catalytic reduction method on the Pt-Re/Al2O3 properties for the n-C7 reforming reaction was studied. The Sn addition was performed in different media (HCl and H2O). It was found that ...
Naphtha reforming Pt-Re-Ge/Al2O3 catalysts prepared by catalytic reduction. Influence of the pH of the Ge addition step
(Elsevier Science, 2008-04)
Pt-Re-Ge/γAl2O3 catalysts were prepared by the catalytic reduction method using different impregnation media (H2O, HCl and NH3) and different Ge contents (0.0, 0.1, 0.3, 1.0 and 2.0%). The influence of these preparation ...
