The hydrodesulfurization (HDS) of the refractory compound 4,6-dimethyldibenzothiophene (DMDBT) normally proceeds through a hydrogenation pathway that removes the planarity of the ring system and makes the hindered sulfur atom more accessible to the desulfurization centers. In this study, a highly active dispersed bimetallic NiFeP catalyst is found to have high selectivity for a direct desulfurization...
In the development of new processes that provide “green energy”, supercritical water (SCW) has emerged as a powerful reaction medium to convert biomass into combustible gases such as hydrogen or methane. Due to typical SCW catalytic process conditions (400°C, 25MPa), in situ characterization of materials and catalysts used in selective biomass conversion is difficult, and accordingly, there is limited...
