The current status of emission of biomass power plants in China According to the newest plan of the National Energy Administration, China’s installed capacity for biomass will reach 13 GW [3] by the end of 2015, which means that about one hundred biomass power plants with a generation capacity of 30 MW for each unit will be structured and put into operation per year from now.
The experimental results[8] showed that the performance of desulphurization and denitrification related to the pore structures and the surface chemistry of activated coke, that the pore volume was the key factor, and that the surface function was an important factor which was the activating center for adsorption and catalysis of SO2 and NO.

Bachu and Bennion (2007) pointed out that the capillary pressure, displacement characteristics and storage integrity are not only influenced by pore structure, saline aquifers and capping layer, but also by pressure, temperature and salinity. 4.4 Linkages between various experiments Interfacial tension is microscopic force, and relative permeability and capillary pressure are macroscopic performance.

The current development of high-precision, high-resolution and structure miniaturized sensors are given priority to with functional sensors..
Light intensity modulation type because of simple structure, large measurement range are applied in general engineering measurement occasions, whose accuracy requirements are not too high; require a higher place on the measurement accuracy using polarization and phase modulation; light intensity modulation, polarization modulation, phase modulation, relatively vulnerable to environmental interference, relatively speaking, the wavelength modulation are convenient and simple, and generally do not need to take corrective action.
Brazing metallized fiber surface chemistry can be directly related to the object to be measured soldering, or further chemical plating thicker, buried in the metal to be tested in vivo [2].

Introduction Manganese oxides A1-xBxMnO3+δ (where A is trivalent rare-earth and B is divalent metal such as Ca, Sr, Ba, Pb) with perovskite structure have been attracting much attention because of their high electronic conductivity and especially since the discovery of their colossal magnetoresistance [1].
It can be seen that the single phase cubic perovskite structure was obtained in LaMnO3 (LMO) and La0.7Ca0.3MnO3 (LCM).

Nevertheless, in order to meet the requirements of a number of new applications, the said tungstates which decide on the nanocomposite structure should be available in the form of a powder.
From the IR spectra shown in Figure 8 it seems that high-purity double tungstate structures can be easily obtained by introducing a SI step.

Porosity of composites is formed by the micro gaps inside concrete matrix, the gaps and flaws at the interfaces between wood pulp and matrix, the hollow spaces in wood structure, the capillaries and spaces between bundles of fibrils and micro fibrils.
Higher cellulose content in wood pulp contributes to a higher penetration of water molecules in the cellulose network structure.

Efficient Oxidative Desulfurization (ODS) of Commercial Diesel with TBHP under Mild Conditions Catalyzed by Polymolybdates Supported on Al2O3 Wan Nazwanie Wan Abdullah1,a, Rusmidah Ali1,b, Wan Azelee Wan Abu Bakar1,c* 1Department of Chemistry, Faculty of Science, Universiti Teknologi Malaysia, 81310 UTM Johor Bahru, Johor, Malaysia anazwanie90@gmail.com, brusmidah@kimia.fs.utm.my, cwanazelee@yahoo.com Keywords: Polymolybdates catalyst, Oxidative desulfurization, diesel, tert-butyl hydorperoxide, dimethyl formamide Abstract Due to the low specifications for sulfur content in diesel, a lot of research work are been conducted to develop alternative method for desulfurization.
The catalysts possess amorphous structure and only dominated by alumina support.
XRD diffractograms showed that the catalyst was highly amorphous in structure and EDX analysis confirmed the presence of Mo and P in the catalyst.
