Abstract

Sodium tantalum oxide doping lanthanum (La-NaTaO3) compounds were successfully synthesized by a sol-gel method and calcined at different temperatures. Tantalum chloride (TaCl5) was used as starting material and lanthanum nitrate (La(NO3)3.6H2O) as lanthanum source. X-ray diffraction (XRD) revealed that the calcination temperature strongly influenced the crystallinity of the prepared samples.The crystallite sizes of the resultant La-NaTaO3were in the range of 27-46 nm. The photocatalytic activities of the samples were examined for hydrogen production from an aqueous methanol solution under UV light irradiation. It was found that the photocatalytic activity of the La-NaTaO3 depended strongly on the calcination temperature. The range of calcination temperatures were 500, 700, and 900°C. The La-NaTaO3 sample calcined at 900°C showed the highest photocatalytic activity compared to the samplescalcined at the other temperatures. The rate of hydrogen production reached a value of 6.16 mmol h-1 g-1 catalyst.

Abstract

Presently, biomass is mostly utilized as co-fuel in coal combustion in view of energy diversification and emission reduction. However, since the coal content of bio-briquettes is high (up to 80% in this study), gas emissions such as those of SOx still occur. Therefore, the introduction of SO2adsorbent is common in coal briquette or bio-briquette combustion. A calcium-based material is usually used for this goal. The aim of this study was to observe the effects of desulfurization temperature and Ca/S ratio (Ca = calcium content in adsorbent; S = sulfur content in coal and biomass) on desulfurization efficiency and kinetics. The ratio of coal to biomass (palm kernel shell/PKS) was fixed at 90:10 (wt/wt) and the ratios of Ca to S were varied at 1:1, 1.25:1, 1.5:1, 1.75:1 and 2:1. The mixtures of coal, PKS and adsorbent were briquetted at a molding pressure of 6 ton/cm2 with Jatropha curcas seeds and starch mixture as binding agents. Desulfurization was performed within a temperature range of 300 to 500°C for 720 seconds at an airflow rate of 1.2 L/min. The results showed that the highest desulfurization efficiency (90.6%) was associated with the Ca/S ratio of 2:1 and temperature of 400°C. Moreover, the highest reaction rate constant of desulfurization was 0.280 min-1.
