A time- and space-resolved deactivation study on the conversion of glycerol to aromatics over H-ZSM-5 was performed. For this purpose, vaporized/pyrolyzed in a pyrolysis section followed by catalytic aromatization step. Benchmark performance showed an induction period ca. 20 min, rather constant BTX yield 25.4 ± 2.2C.% for 3–4 h time stream (TOS). Subsequently, rapid drop observed due catalyst ...
Workers in the coking, foundry, and aluminum industry can be exposed to high concentrations of polycyclic aromatic hydrocarbons (PAHs) and are at increased risk for lung cancer, as are cigarette smokers. In recent years several studies on workers in the foundry and coking industries have been reported. In these studies, white blood cell(WBC) DNA was used for analysis of PAH-DNA adducts. Theoret...
This review considers problems related to design of efficient structured catalysts for natural gas and biofuels transformation into syngas. Their active components are comprised fluorite, perovskite spinel oxides or their nanocomposites (both bulk supported on high surface area Mg-doped alumina MgAl2O4) promoted by platinum group metals, nickel alloys. A complex modern structural, spectroscopic...
