Conversion of D-xylose into furfural with aluminum and hafnium pillared clays as catalyst
The industrial practice used to produce furfural is the dehydration of pentoses, which is carried out using highly corrosive and contaminating mineral acid catalysts. Because of the ecological and toxicological threats of ...
Mild microwave-assisted synthesis of aluminum-pillared bentonites
(Springer, 2017-03-21)
Two types of bentonites were modified using a cleaner method to prepare aluminum-pillared clays. This methodology involved a purifying stage, an intercalation process, and a microwave irradiation step at low energy power. ...
An introduction to pillared clays.

Effect of the Al/clay ratio on the thiabendazol removal by aluminum pillared clays
(Elsevier, 2014-01)
In thiswork, four aluminumpillared clays (Al-PILC)with different Al/clay ratioswere synthesized and evaluated for the removal of thiabendazole (TB) (a fungicide widely used in agricultural activities) from aqueous media. ...
Adsorptive, thermodynamic and kinetic performances of Al/Ti and Al/Zr-pillared clays from the Brazilian Amazon region for zinc cation removal

Conversion of d-xylose into furfural with aluminum and hafnium pillared clays as catalyst
(Universidad Nacional de Colombia Sede Medellín, 2013)
The industrial practice used to produce furfural is the dehydration of pentoses, which is carried out using highly corrosive and contaminating mineral acid catalysts. Because of the ecological and toxicological threats of ...
Thermal transformations up to 1200 °C of Al-pillared montmorillonite precursors prepared by different OH–Al polymers
(Springer, 2017-04)
Aluminum-pillared montmorillonites are useful materials for their application as catalysts, adsorbents and ceramic composites. The precursor is a pillared montmorillonite that is not thermally stabilized. The precursor ...
Desenvolvimento de novos materiais a base de argilas pilarizadas contendo níquel e alumínio
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2021-02-24)
Three bentonite clays from deposits located in Brazil were used to study the pillar
parameters such as the use of heating in the synthesis of the pillar agent; it was verified
the feasibility of controlling the density of ...
