Several kinds of Tungstophosphates of Heteropoly Compounds （TPHC） with different compositions and the same structure were synthesized using the method of solid-phase reaction to change the tool ratio of Na4P2O7·10H2O, WO3 and Na2WO4 · 2H2O. TPHC, as a catalyst, was used in oxidative desulfurization of diesel. The results show that TPHC has catalytic activity. With THPC existing, the highest desulfurization rate reaches 51.85%, 32.6% higher than that yield without TPHC. And the desulfiarization rate increases with decreasing WO3. FT-IR spectra of TPHC shows that the catalytic activity is related to the activity of end oxygen（Od）.The more active Od is, the stronger the capability of obtaining or losing electron is. It means that TPHC has a good catalytic activity. FT-IR spectra of TPHC indicates that desulfurization rate is in linear correlation with Iw-Od/Ip-Od/ Iw-Od is intensity of W-Od vibration band, Ip-Od is intensity of P-Od vibration band） and correlation coefficient reaches 0.965.

The main technical conditions for synthesizing 4A zeolite with kaolin were determined. The whiteness and calcium ion exchange capacity (CIEC) of the product were increased by calcining and screening the colouring ions, and the high quality 4A zeolite was synthesized successfully. Moreover, the formation mechanism of zeolite also discussed.

To meet some special requirements such as paper filler,ceramic titanium white and synthetic 4A zeolite, the raising whiteness of calcined kaolin has become more and more important. The calcined experiments were carried out with and without additive to increase the whiteness of calcined kaolin. Results show that additive of chloride (A) or oxides can obviously increase the whiteness of calcined kaolin. Meantime,the mechanisms of enhancing the whiteness of calcined kaolin were discussed.

Wastewater from the production of cellulosic ethanol was treated by the processes of internal micro-electrolysis method ＋ABR＋UASB ＋MBR. The results of running indicated that, when COD is 12000 mg/L and HRT of UASB is 48 h, the COD removal rate reaches 72% and HRT of MBR is 20 h, COD removal rate is between 80.8% and 87.5%. The effluent COD concentration stabilized at 301- 537 mg/L, it indicates that the MBR system has a strong ability to resist impact load.

The depression mechanisms of tannin on the diopside surface have been studied by the rise of Infrared spectroscopy (IR), simulated pulp and mixed solution tests, It is found that the first order hydroxy completes of calcium are able to interact with tannin, and to form chemical complexes. es. The functional groups in tannin molecules participating in the chemical complexation are the hydroxyl groups, and carboxyl groups derived from the hydrolysis of hydroxyl groups.

The floatabilities of single mineral samples of Tvollas-tonite and diopside have been studied with addition of a cationic collector , dodecylamine hydrochloride (DDA ?HC1) , and modifiers. A mixture of two minerals was successfully separated , when DDA ?HC1 and tannic acid (as depressant)were used together . The interaction between tannic acid and wollastonite and diopside in the pulp and the adsorption of tannic acid on the surface of the two minerals was sttidide with the help of ultra-violet (UV) spectroscopy and X-ray photoelectron spectroscopy (XPS) , re-spectively.

Surface modification of sericite by wet method was conducted with the addition of 1.0 % （w/w） silane. The resulting wetting contact angle and activity ratio of sericite were 130° and 98% respectively. Good pre-evaluation indexes of oil value （40.8%） and dispersivity （14.0 mL） were obtained. When 30 % of sericite was filled into acrylonitrile butadiene styrene（ABS） plastic, the bending strength and tensile strength of the composite material were reduced by 7% and 14.3% in comparison to those of pure ABS plastic, while the rigidity was increased by 3 times, and the impact strength and breaking elongation were reduced significantly. The mechanism of surface modification was investigated and the configuration of silane coupling agent on the surface of sericite was given. Infrared （IR） spectroscopic analysis indicates that the adsorption of silane on the surface of sericite belongs to chemical adsorption.
