In this study, three solid acid catalysts, namely mesoporous aluminophosphate-supported 12-tungstophosphoric heteropoly (HPW/MAP), aluminosilicate-supported (HPW/MAS), and gamma alumina-supported (HPW/?-Al2O3) were prepared characterized. Mesoporous aluminophosphate (MAP) aluminosilicate (MAS) synthesized via sol-gel hydrothermal methods, respectively, 25 wt.% of (HPW) was immobilized on the su...
The acute and accumulated toxicity of the rare earth borotungstate heteropoly blues, HPB-2, Ce2H3[BW9(VI)W2(V)Mn(H2O)O39].12H2O, which is active against influenza virus in Kunming mice, were investigated in Kunming mice following oral and intraperitoneal administration. The activity of HPB-2 against influenza virus (FM1) in the mice was then investigated. HPB-2, given either orally (p.o.) or in...
Pyrolysis oil derived from waste tires consists of sulfur content in the range 7000 to 9000 ppm. For use diesel engines, its must be lowered 10 15 Though conventional hydrodesulfurization is suitable for removal tire pyrolysis oil, high cost provides an avenue alternative desulfurization technologies explored. In this study, oxidative (ODS), a low-cost technology, was explored oil. Two categori...
