Preparation and Hydrodesulfurization Performance of New Kind of Diesel Oil Hydrogenation Catalyst
Zhang Zhiwei, Ding Wei, Zhao Dezhi, Song Guanlong, Zhang Qiang
Abstract640)      PDF (2683KB)(469)      
The nanometer autonomous vehicle assembly MoNiP hydrogenation catalysts were prepared by homogeneous precipitation using thiourea as precipitant matrix and citric acid as complexing agen. The catalysts were characterized by BET, NH3TPD, FTIR spectra of CO adsorbed and XPS. The results of BET and FTIR spectra of CO showed that when the content of thiourea was 40%, catalytic performance of the catalyst was best. The homogeneous precipitation catalyst achieved the desulfurization rate of 95.3% which was higher than the reference catalyst by 1.7%.

Abstract528)      PDF (2836KB)(369)      
The macroporous alumina carrier as the host of catalysts were prepared by supersolubility stiu selfassembly method. The properties of carrier were characterized by BET, TEM, XRD and so on. In MoNiP solution, macroporous hostguest catalyst was prepared using the positive micelle as template. The effect of different amount and type of surfactant on the formation of micelles was examined. The most appropriate amount of template was optimized. The hostguest macroporous catalytic materials were characterization by BET and electron microprobe analysis method (EMPA). The results showed that the catalytic material had pore volume of 0.38 cm3/g, specific surface area of 61~ 90 m2/g, average pore size of 9.3 ~13 nm, most probable pore diameter of 12.5 nm and 45 nm. The pore size distribution in the range of 10 ~60 nm were highly concentrated which occupied about 53%~70%. The amount of active metal was between 18% and 27%, and it evenly dispersed in the catalyst by EMPA analysis. 

Ding Wei,Wang Jiao,Xie Jianbo
Abstract462)      PDF (1131KB)(355)      
The low permeability reservoir characteristics and overall damage mechanism in Daqing were studied, water blocking damage is one of the most important type of injury. By reservoir damage mechanism analysis, Daqing oilfield Longxi area water blocking damage between 10.41%~14.29%. Therefore, this paper mainly through water lock damage mechanism indoor, preferred and evaluation of waterproof lock agent. Optimizing and evaluating antiwater lock agent indoors, antiwater lock agent DW3 greatly reduce the filtrate interfacial tension. Antiwater lock drilling fluid, which was used in field test shows that: Pilot evaluated the permeability recovery value of drilling fluid system reached 88.14%. Formed the special technology of antiwater lock in Daqing oilfield, achieved the purpose of protecting reservoirs.

ZHANG Jinhui,WANG Dingcong,DING Wei,et al
Abstract477)      PDF (1644KB)(269)      
Adopting nano selfassembly method of the second time to prepare nano selfassembly catalyst, the pore size of the catalyst , the pore size distribution and specific surface were analyzed by using adsorption method of N 2,It was found that the aperture of nano selfassembly catalyst almost concentrated in 30-100 nm by comparing the basic property, accounting for 36.13% of the catalyst total pore size.Using catalytic diesel oil as raw material, the activity of nano selfassembly catalyst and reference dose which were desulfurization, denitrification, aromatics saturation were evaluated in microreactor. The results show that after the reaction of 20 s, the desulfurization rate of nano selfassembly catalyst is 90.13%, denitrification rate is 92.62%, aromatics saturation rate is 73.18%.

Abstract452)      PDF (2728KB)(440)      
Catalyst FA2012 were prepared by the secondary nano selfassembly technique. It has larger pore volume and higher metal dispersity.The crystalline phase structure, microstructure and metal distribution of catalysts were characterized by the XRD,TEM and BET that proved the conclusion of FA2012 was multilayer and formatted nanoparticles.The pore diameter, pore volume and specific surface area of it were 12.3 nm,0.37 cm3/g and 219 m2/g. The metal content of unit volume reactor of FA2012 is about 1/4 of reference agent F2.The results of activity evaluation show that the conversion rate of sulfur, nitrogen, arene and colloid in hydrotreated residue were 61%,16% and 45% by FA2012, respectively. The reference agent were 40%,24% and 25% by F2 in hydrotreated catalytic cracking diesel miscella.It proved that the anti coking performance of FA2012 is better than industrial catalyst F2.
