SUMMARYHigh resolution seismic in the sequence stratigraphic research of Quaternary

sediments in the continental shelf of Vietnam

Mai Thanh Tan,University of Mining and Geology

Quaternary sedimentary covers almost of the continental shelf of Vietnam, holding importantroles in marine geologic structure. However, researches on them are still very limited. Inorder to resolve these problems, the high resolution seismic method have been applied. Basedon using seismic stratigraphy and sequence stratigraphy, the high resolution seismic datawere interpreted.In this paper, the author present some new results of seismic stratigraphyanalysis of the high resolution seismic data, in order to define the sequence boundaries,characteristics and distrisbution of Quaternary sediments within the continental shelf ofVietnam.

SUMARYEffects of wellbore deviation on cuttings bed formation in cuttings transport and

cuttings bed anti-sliding velocity

Pham Duc Thien, University of Mining and Geology

Cuttings transport is important work and always accompany in drilling oil and gas wells.With the purpose increase wells useful and togerther with modern technology, the high angle

and horizontal wells more and more are wide used. When the wellbore angle is changed, thecutting transport mechanism is also changed cause by forming cutting bed in the wellbore.The results of studying and detail review, the author proposed three segments wellboredeviation with different properties are as follows: a vertical segment, all the cuttings be

suspended; a transit segment, forming a moving cutting bed, and a horizontal segment,forming a moving cutting bed and a stationary cutting bed. At once, by using continuityequations and force balance equations wich acting on the cutting bed, since then proposeanti-sliding down condition of cutting bed and minimum anti-sliding velocity of dispersed

suspension layer in transit segment.

Pham Trung Kien, Pham Xuan Nui

University Mining and Geology

In this paper, 10%CuO/TiO2, 10%CuO/-Al2O3 materials were synthesized for treatment ofCO in exhaust gases. Physico-chemical properties of catalysts were characterized by XRD,

BET Adsorption and SEM. The catalyst activity and the effects of temperature (in the range of100-300oC) on the conversion were investigated. 10%CuO/TiO2 has been shown to be thebest for complete conversion of CO to CO2. It can completely convert CO to CO2 at 200

SUMMARYLe Thi Hoai Nam, Nguyen Thi Thu Trang, Tran Quang Vinh, Nguyen Thi Thanh Loan,

Nguyen Thi Nhiem, Tran Thi Ngoc DungAg/TiO2 nano-antibacterial material was prepared using sodium citrate as a reducing agent.The size and shape of the nano-materials were characterized with scanning electronmicroscopy (SEM) and transmission electron microscopy (TEM). The results showed that theaverage particle size of TiO2 among these nano-materials was around 80120 nm, and theaverage particle size of nano-silver was around 10 nm. Formation of Ag nano-particles on

the surface of TiO2 was confirmed by X-ray diffraction (XRD) and Raman spectroscopy, andthe antibacterial activity was also investigated. By the antibacterial activity study, it is notedthat the role of Ag on the growth inhibition rates against E. coli was evident when compare

Ag/TiO2 nanocomposite with commercial TiO2 under UV irradiation and in the absence ofUV. The study results showed that antimicrobial effect was 100 % as the initialconcentration of E. coli was 1.1 x 106 cfu/ml and contact time was 10 minutes with thecontent of nanosized materials being more than 0.5 wt%.

The mesopore material -Al2O3 synthesized by using surfactant Triton X 100 having thespecific surface area of 355 m2/g and the medium pore dimeter of 54. Pore distribution of-Al2O3 is uniform so that KI particles can be kept on -Al2O3 surface. The -Al2O3 can be usedas a carrier in the biodiesel synthesis reaction (yield over 90%).

SUMMARY

The process of Zeoforming is based on the reactions of catalytic conversion of paraffins and

naphthenes over zeolite-containing catalysts. Its main products consist of unleaded, highoctane gasoline and LPG. The technology has shown numbers of advantages in comparisonwith traditional process Reforming. Hence, synthesis researches on this field are essential torenovate our technique and have a total overview of applying this in Viet Nam. This articlewill focus on Zeoforming key features and parameters as well as outlining some potentialdirections that can carry out in Viet Nam.
