Cu-supported on Sodium-treated Sepiolite for Selective Catalytic Reduction of NO by Propylene Zhihao ZHANG1, Yang LI1, Yunfang QI1, Qing YE1,a*, Shulan Ji1 and Dao WANG1 1Key Laboratory of Beijing on Regional Air Pollution Control, College of Environmental and Energy Engineering, Beijing University of Technology, Beijing 100124, China ayeqing@bjut.edu.cn Keywords: Selective Catalytic Reduction of NO by Propylene; sepiolite; Cu Abstract.
Selective catalytic reduction with hydrocarbons is one of the most extended and efficient commercial DeNOx processes for nitric oxide removal from stationary sources.
Reports on a large number of catalysts for the selective catalytic reduction (SCR) have appeared since 1990, being the majority of these catalysts ion exchanged zeolites [1].

Then CO2 emission is calculated in the RHF—EAF flow for treating V-Ti magnetite according to data from the pilot plant in Pangang Group.
Based on the data from design and real production the text calculated the quantum of CO2 emissions.
According to these data above we can calculate the ratio of blast furnace gas and coke oven gas and the result is that among the gas mixture blast furnace gas accounts for 60% ,of course the rest is coke oven gas.
The carbon content of metallized pellets is about 5% and the carbon content in the hot metal is around 2%.According to the mass balance calculation we can get the data of CO2 emissions to produce one ton hot metal.
The calculation is based on the energy consumption which is different from the calculation of the RHF-EAF process and all of the data come from the real production.

(b) Pre-processing of the data is done to assess the extent of coverage of training data in the domain of prediction.
Put all the calculated charge data in file Stop No Yes Fig 1.
The data servers communicate with devices in the field through PLC.
The data servers poll the controllers at a user defined polling rate.
The controllers pass the requested parameters to the data servers.

However, in typical image recognition in 1D vectors space, where the number of data samples is smaller than the dimension of data space, suffering from the singularity problem of matrix, NPE algorithm cannot be implemented directly.
However, they are defined only on the training data points and cannot show explicit maps on new testing data points for recognition problem.
In both experiments, we split randomly the data set into two parts.
And relative to 2DLPP and B2DLPP, 2DNPE and B2DNPE have total different ways to preserve local structure of data manifold.

The top-down technique bases on size reduction by physical mechanism such as high pressure homogenization, media milling [2] and sonication [3].
To develop the simple process for particle size reduction simple homogenization and melt emulsification technique were investigated and followed by sonication process.
The rheology behavior of all formula was Newtonian flow (data not show).
The zeta potential was -10 to -25 mV which was slightly decreased by sonication process (Data not shown).
The particle size reduction was successful with sonication method.

Application of Auxiliary Antenna Elements for SAR Reduction in the Human Head M.
This technique provides approximately 20% reduction in the SAR value as well as 2.8 dB reduction in antenna received power [6].
SAR reduction depends on the size and shape of ferrite material also.
The results reported in [12] indicate 57.75% SAR reduction.

- Soot particles data Table 1.
) - Cutting, sliding, fatigue data Table 2.
To find a suitable Sugeno FIS which describes the selected data it is appropriate to divide the data into tuning and checking data.
There are two basic ways of dividing the data: - - dividing the area (which includes turning data) into smaller parts.

Reduction in area is a measure to determine formability on cold heading.
Reduction in area is affected by second phases and inclusions.
Tensile strength-reduction in area balance Figure 6(a) and (b) shows the variation of percentage elongation and reduction in area as a function of the volume fraction of cementite.
The test data of conventional ferrite+pearlite steel [12], tempered martensitic steel [12] and bainite steel [13] are also plotted in Fig. 7 for the purpose of comparison.

Strength Reduction Elasto-plastic finite element is a method that combined with the strength reduction technique, the limit equilibrium theory and the principle of elastic-plastic finite element, which firstly determine the stress, strain or displacement field of slope for a given strength reduction factor.
And the reduction factor is defined as the slope stability safety factor.
He thought that elastic strength reduction finite element method has strong adaptability.
design and measured data, the calculation models are shown in Fig.2~Fig.7.
