Cover Story: The concept of alternating pore filling with Fischer-Tropsch wax and subsequent pore drainage by hydrogenolysis has been shown to be very effective in this publication, as it not only improves the overall activity and methane production rate, but also significantly increases the kerosene selectivity of the overall process. It was also found that high reaction temperature leads to comparatively low methane selectivity in hydrogenolysis.View this paper.

Production and Characterization of Carboxymethylcellulase by Submerged Fermentation of Moniliophthora perniciosa

Received: 24 December 2022;  Published: 12 June 2023;  doi: 10.21926/cr.2302019

Abstract

Microorganisms that are capable of degrading lignocellulolytic materials can produce extracellular cellulase complexes. Microorganisms are an excellent alternative for the production of cellulolytic complex, since these sources have a high power of multiplication. In this work, we researched the production by the fungus Moniliophthora perniciosa. The production and pH and temperature optimum optimization were studied by Response surface methodology and carboxymethylcellulase [...]

Influence of Bifunctional PtZn/SiO2 and H-ZSM-5 Catalyst on the Rates and Selectivity of Propene Aromatization

Received: 28 March 2023;  Published: 06 June 2023;  doi: 10.21926/cr.2302018

Abstract

Previous studies on the conversion of olefins to aromatics with bifunctional Ga- or Zn-ZSM-5 catalysts have concluded that benzene, toluene, and xylenes (BTX) yields are significantly higher than for ZSM-5 alone. These results were attributed to the higher aromatic dehydrogenation rate of Ga or Zn. In this study, a highly active, bifunctional PtZn/SiO2 (1.3 wt% Pt, 2.6 wt% Zn) with H-ZSM-5 (Si/Al = 40) catalyst is investigated for propene aromatization at 723 K and 823 K. [...]

Synthesis and Characterization of MCM-41 Nanomaterials Containing Titanium and Application for Catalytic Oxidation of BTEX

Received: 17 August 2022;  Published: 30 May 2023;  doi: 10.21926/cr.2302017

Abstract

The TiO2/MCM-41 nanomaterials were synthesized by impregnation with an excess solvent with different percentages of titanium dioxide. They were used for catalytic degradation of Benzene Toluene Ethylbenzene and Xylenes (BTEX) in the presence of hydrogen peroxide in aqueous media. The obtained materials were characterized by X-ray Diffraction, nitrogen adsorption-desorption using the BET method and Fourier Transform Infrared Spectroscopy. The nanostructured phase of the hex [...]

Obtaining TiO2 Nanostructures by Electrospinning and Analysis of Absorbance in the UVA Spectrum for Photocatalytic Application

Received: 14 December 2022;  Published: 17 April 2023;  doi: 10.21926/cr.2302016

Abstract

The synthesis of fibers by electrospinning allows for obtaining nanostructures of one-dimensional materials with good flexibility, optical and catalytic properties, high surface area and porosity. They can be used in applications such as: catalysts, solar cells, fuel cells, membranes, and hydrogen batteries, among others. Here we emphasize that few reports in the literature describe the existing synergism between the optical and photocatalytic properties of TiO2, and the i [...]

Organic Structure-Directing Agent Free Synthesis of Mordenite with Seeds, Used as A Support for Mo Catalysts in the Transesterification of Soybean Oil

Received: 20 December 2022;  Published: 07 April 2023;  doi: 10.21926/cr.2302015

Abstract

This work prepared mordenite using seeds and without organic structure-directing agents (OSDAs). The Mo/Mordenite was prepared through wet impregnation and the catalysts’ performance was checked for transesterification of soybean oil with methanol. The mordenite zeolite was prepared through hydrothermal crystallization under static conditions with a molar composition of 6Na2O:Al2O3:30SiO2:780H2 [...]
