Hydrodeoxygenation of guaiacol over pt/ga-mesoporous catalysts
(2020)
La hidrodesoxigenación (HDO) de guayacol, utilizado como molécula modelo, ha sido estudiada en un reactor batch sobre catalizadores de platino soportado sobre SBA-15 a 12 atm de presión y diferentes temperaturas, utilizando ...
Multiple-wall carbón nanotubes obtained with mesoporous material decorated with cerio-zirconium
(2020)
In this work, Ce-Zr-SBA-15 has been used directly as a catalyst for the synthesis of multi-vall carbon nanotubes (MWCNT) through Chemical Vapor Deposition (CVD). In addition to cerium oxide, it contains zirconium oxide ...
Superacid mesoporous carbón base don sulfated Zr
(2020)
In this brief communication we report the successful preparation of a promising material with acidic properties from starch-derived mesoporous carbon (SMC), functionalized with sulfated zirconia. The process of assembling ...
Mesopore carbón starch with acid properties: synthesis and characterization
(2020)
We have shown that a promising material with acidic properties can be successfully prepared from starch mesoporous carbon (SMC), functionalized with sulfated zirconia. The process of assembling P123, starch, zirconia, and ...
Super-acid sulfated/zirconium-containig nanostructured carbons
(2020)
In this work, we report the successful preparation of a superacid mesoporous carbon functionalized with sulfated zirconia (SZr-C). SZr-C has a surface area of approximately 1300 m2 g-1, and the total pore volume of 0.94 ...
Influencia del proceso de síntesis de materiales mesoporosos ácidos en la obtención de hmf a partir de fructosa
(2020)
Motivados por el agotamiento irreversible de los recursos fósiles, en la actualidad se realizan esfuer-zos en obtener moléculas orgánicas de valor agregado a partir de biomasa. El 5-hidroximetilfurfural (HMF) es, junto al ...
Catalytic oxidation of sulfur compounds over Ce-SBA-15 and Ce-Zr-SBA-15
(2021)
The catalytic oXidation of different sulfur compounds, commonly present in liquid fuel, was studied over a series of ceria and ceria-zirconium based oXidation mesoporous catalysts. SBA-15 was synthesized using sol-gel ...
EXperimental design optimization of the ODS of DBT using vanadium oXide supported on mesoporous Ga-SBA-15
(2020)
EXperiment design-response surface methodology is applied in this work to model and optimize the o Xidation of dibenzothiophene (DBT) using VOX-Ga-SBA-15 catalyst. The analyzed variables are the influence of the nature of ...
Iron-modified mesoporous materials as catalysts for ODS of sulfur compounds
(2020)
Fe-modified mesoporous catalysts were used in the ODS of DBTs using H2O2 as oXidant and acetonitrile as solvent. SBA-15, MCM-48, CMK-3 and CMK-1 were used as supports. Iron was incorporated using iron nitrate by wetness ...
