Novel Catalysts Based on Synthetic Mesoporous Silicates of the MCM-41 Type and Hydroxyapatite for Desulfurization of Model Fuel

Ceramics
Nanopowders of hydroxyapatite (HA) and Fe-substituted hydroxyapatite (HAFe) were synthesized by wet precipitation on either MCM-41 (a synthetic, mesoporous aluminosilicate material) or an aluminum-containing MCM-41 (AlMCM) support.

Hydrodesulfurization of Dibenzothiophene: A Machine Learning Approach

ChemistryOpen
AbstractThe hydrodesulfurization (HDS) process is widely used in the industry to eliminate sulfur compounds from fuels. However, removing dibenzothiophene (DBT) and its derivatives is a challenge. Here, the key aspects that affect the efficiency of catalysts in the HDS of DBT were investigated using machine learning (ML) algorithms.

The Sulfur Conversion Functional Microbial Communities in Biogas Liquid Can Participate in Coal Degradation

Polish Journal of Microbiology
The addition of biogas liquid is a practical way to improve the yield of biological coalbed methane. The microbial composition in biogas liquid is complex, and whether it could participate in the sulfur conversion of coal remains unknown.

BIOTRANSFORMATION AND REMOVAL OF SULFUR FROM DIBENZOTHIOPHENE USING IMPROVED BIOCATALYTIC METHODS

CT&F Ciencia, Tecnología & Futuro, 1998
Three methods for the removal of sulfurfrom dibenzothiophene were evaluated using biocatalytic processes. The methods were a microbial, an enzymatic and a combined one that involves a previous enzymatic oxidation followed by microbial degradation.
