Influence of Preparation Factors on Ca/P Ratio and Surface Basicity of Hydroxyapatite Catalyst
Hydroxyapatite Calcium/phosphorus ratio Basicity Basic site density
2009/8/4
We aimed at precision control of the basicity of hydroxyapatite (Ca10(PO4)6(OH)2; HAP) and paid attention to four key factors in the synthesizing process—the solution's Ca/P ratio, pH, temperature and...
Effects of Molar Ratio, Catalyst Concentration and Temperature on Transesterification of Triolein with Ethanol under Ultrasonic Irradiation
Triolein Ethanol Ultrasonic irradiation Biodiesel Base catalyst
2009/7/28
The transesterification of triolein with ethanol to make biodiesel fuel was investigated under ultrasonic irradiation to evaluate the effects of the amount of base catalyst (NaOH or KOH), molar ratio ...
Effect of SiO2/Al2O3 Ratio and Crystalline Structure of Zeolite on Hydrogenation and Hydrodesulfurization over Pt-Pd Catalyst Supported on USY Zeolite
Palladium platinum catalyst USY zeolite Desulfurization Hydrogenation
2009/7/27
Effects of the carrier characteristics were studied on the catalytic properties of Pt-Pd-supported USY zeolites in the hydrogenation of tetralin and the hydrodesulfurization of 4,6-dimethyldibenzothio...
