Exhausted fluid catalytic cracking catalysts as raw materials for zeolite synthesis
(Elsevier Science, 2006-07)
The utilization of exhausted fluid catalytic cracking (FCC) catalysts as raw materials for the zeolite synthesis was analyzed. Samples of the catalysts directly released from FCC units and the corresponding impact grinding ...
Synthesis and comparison of the activities of a catalyst supported on two silicate materials
(2017-04-15)
The focus of this work is inspecting the synthesis and comparison of the activities of a catalyst supported on two silicate materials in the epoxidation of 1-octene. The two new catalyst materials were characterized by ...
Synthesis and characterization of hyperbranched polyethylenes made with nickel-alpha-diimine catalysts
(Wiley-Blackwell, 2002-12-20)
The role of the coprecipitation sequence of salt precursors on the genesis of Cu-ZnO-Al2O3 catalysts. synthesis, characterization and activity for low temperature shift reaction
(1998-06)
Cu-ZnO-Al2O3 catalysts for the low-temperature water-gas shift reaction were prepared using methods of direct and reverse coprecipitation. The catalysts obtained were characterized by DRX, TPR, XPS, N2O chemisorption, ...
Oxygenated biofuels: Synthesis of fatty acid solketal esters with a mixture of sulfonated silica and (Bu4N)(BF4) catalyst
(2019-02-01)
Amorphous SiO2-SO3H [1] with a small surface area and 1.32-mmol H+/g was used for the one-step preparation of solketal from glycerol and acetone; a 20%-w/w catalyst mixture (10% [1] and 10% (Bu4N)(BF4) was found to be very ...
Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
Acid catalyst influence on the polymerization time of polyfurfuryl alcohol and on the porosity of monolithic vitreous carbon
(2016-05-20)
This study compares the influence of different acid catalysts on the polymerization rate of polyfurfuryl alcohol (PFA) precursor and especially on the respective porosity of Monolithic Vitreous Carbon (MVC) produced from ...
Superficial properties of activated carbon fiber catalysts produced by green synthesis and their application in water purification
(Springer Heidelberg, 2020-07)
Catalysts of Pd-In supported on activated carbon fiber were synthesized, characterized, and evaluated for the removal of nitrogen oxyanions from water. The work was carried out aiming the development of a green synthesis ...
