Recently, these have been studied by many scholars at home and abroad[4-8], but the complete CO2 capture data of long-running power plant is absent, and most of the datum are from different systems and part of the datum are assumed which maybe exists a big deviation to the actual situation.
For more than one year operating, a number of reliable data are accessed, which lays a solid foundation for research.
Power plant is equipped with selective catalytic reduction (SCR) de-NOx system, electrostatic dust removal system and limestone-gypsum wet desulphurization system. 1.
Though the scale of carbon capture demonstration project in Gao Bei-dian plant is small, it greatly promotes the development of carbon emission reduction.
The Second Power Plant of Shanghai Shi Dong-kou which operated in late 2009 is the actual carbon capture engineering application, and it plays an important role in carbon reduction work in China.

Introduction Nowadays, due to unique electronic structure and good conductivity molybdenum carbides (MoCx) are widely used as catalysts in various reactions: nitrogen reduction reaction (NRR), CO2 reduction reaction (CO2RR), hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) [1].
Molybdenum carbides can be synthesized by various techniques, including calcination [4], tuning carburization atmosphere and temperature of the precursor [5], pyrolysis [8], chemical vapor deposition (CVD) [13, 14], through the first reduction reaction and the following carbonization process [15], mechanochemical synthesis [16], using a temperature programmed reaction procedure [17] etc.
The obtained data were used to estimate the average power of the plasma effect by multiplying the current array by the voltage array and the amount of supplied energy by integrating the power over time.
According to the obtained data, it is possible to indirectly estimate the energy efficiency of the synthesis process: with an increase in the mass of the initial mixture from 0.5 g to 2 g, the specific amount of energy relative to the initial mass decreases from 520 kJ / g to 130 kJ / g.
According to X-ray diffraction data, the samples have a crystal structure: there are two phases of molybdenum carbide - Mo2C and Mo1.2C0.8, and an ultradispersed graphite phase is also present in the samples.

ODF's (Orientation Distribution Function), were computed either from X-ray pole figures or from EBSD individual orientation data sets by using the harmonic method.
The sheet was cold rolled with a laboratory rolling mill up to a final thickness reduction of 80% (corresponding true strain ε=1.61).
After 80% of thickness reduction, the texture of cold rolled Zr702 is characterized by a broad peak centered at {ϕ1=0°, Φ=30°, ϕ2=0} visible in the ϕ1=0° ODF section in Fig. 1.a.
In Fig.2.b the raw map has been filtered (neighbourhood orientations have been affected to notindexed data points) in order to visualise misorientations between indexed pixels.
The band contrast of not-indexed data points is always very low.a) 10 mm NDRD C m B m A m RD DT b) RD DT Figure 3.

To eliminate any effect of drilling operation on the surrounding soil and obtain stable, correct original temperature and thermophysical parameters of subsurface soil, both buried tube thermal exchange wells were left undisturbed for 72h before the test started. 1.3 Testing apparatus and process A rock-soil thermophysical testing apparatus consisting of a stainless steel electric heating insulated water tank, a circulating water pump, a stainless steel pipe system, a power distribution system, a flow sensor, temperature sensors, a power transmitter and a data acquisition unit integrated on a bench was used for the test as shown in Fig. 1. 1.
Temperature data during the test was automatically acquired to the precision of three digits after the decimal point.
Fig. 2 shows the temperature data of the local rock-soil body in this area.
The equivalent coal reduction to the heat so derived is 3.7×1010J.
The coal reduction, in turn, will result in reduction of CO2 emission by 1.12×1010t, SO2 emission by 7.99×107t, Nox emission by 2.82×107t, suspended dust emission by 3.76×197t and solid coal ash emission by 4.7×106t.

Original 3D CAD data of desired model are sliced in dedicated software into layers of a specific thickness.
Last step in data preparation was slicing the resulting models into layers 50 μm thick in the AutoFAB software.
After the data were prepared, the job was submitted to SLM 280HL machine.
According to the freely available data which concerns AlSi12 material [4], its standard mechanical properties are as following: E = 72 000 to 75000 MPa, Rm = 150 to 230 MPa and εmax = 5 to 12%.
The data obtained in this article corresponds to more hardened structure which is a consequence of SLM method.

Data reduction, background description and the final structural refinement were carried out with TOPAS 4.2 and its program package.
The refinement was performed within the space group Im3 (R-Bragg 4.182) yielding the crystal structure data collected in Table 1.
The dashed and dotted line is a CW fit to the data in the temperature range 200-300 K and 2.5-6 K, respectively.
The lower insert displays a close-up of the lowtemperature data with the magnetic transition temperature Tmag and the temperature T0 at which correlations between the 4f moments set in.
The solid line is a linear fit to the data below 0.1 K emphasizing the non-Fermi liquid behaviour ∆ρ = AT with A = 2.77 µΩcmK−1.approximately 5% with respect to the value −2.05 obtained for Ce4Pt12Sn25.

We suggest that a similar gettering effect of implanted ions into 4H-SiC could explain the data obtained.
These data confirmed the improvement of the structural perfection of the 4H-SiC CVD epitaxial layers near the Al ID p +n junction position after its formation indicated above.
Also TEM data showed the absence of amorphous layers usually created by high dose Al ion implantation [7].
SIMS data shows that an Al box-profile was formed with Al atom concentration of about 5×1020 cm-3 after Al ion implantation and annealing (Fig. 2).
Hall data for Al ion implanted p +-layer after a short high temperature annealing: (a) free hole concentration and (b) its mobility, (c) resistivity of the p+-layer.

Fields covered by Grey theory include systems analysis, data processing, modeling, prediction, as well as decision making and control.
The Grey-forecasting Model (GM) is the core of Grey Theory, the grey model represented by GM (n, h) predicts its own trend by a dynamic different equation established on the history data.
Supposing the history data series is represented by, and the model GM (1, 1) is as follow:
So the accumulated generating operation (AGO) result of the history data series is as follow:
Therefore, the grey assessment method can provide an initial prioritization of future dam safety investigations, potential structural and non-structural risk reduction measures.

− smaller total reduction during hot rolling
It is necessary to recognize that the majority of the published data have been obtained from laboratory heats, while in a smaller amount of works the analysis has been focused on industrial samples.
On the other hand, in the case of Ti-Nb steels, a reduction of Cu content was proposed, as it was observed that coprecipitation of (Ti,Nb)(C,N) could occurred on previously formed CuS particles [17].
Furthermore, from the data of Ref. 34 it is observed that if an important amount of Ti remains in solution, this element, as Nb, may also produce retardation on the recrystallization kinetics.
Fig. 8 shows an example of the data provided by the model.

According to the data obtained, the at% of Al2O3 in the deposit increases sharply with increasing the concentration of Al2O3 in the electrolyte and attains the optimum values at 14.4 at% at 30 g/l Al2O3 suspension in the bath.
The data obtained in this investigation can be explained in terms of adsorption of Al2O3 on the cathode surface.
As a result, the reduction of copper ions is controlled by concentration overpotential, the amount of codeposition of Al2O3 particles gradually decreases.
This results in the reduction of the diffusion layer thickness and it is accompanied by the increasing of the metallic ion concentration in the diffusion layer.
