Research ArticleOpen accessPhrase in the titleThe Development of Ni/Dolomite Catalyst in Simultaneous Biomass Gasification and Reforming in Fluidized BedAnawat Ketcong, Tharapong Vitidsant, Kaoru FujimotoSimultaneous gasification and steam reforming of the biomass on Ni/dolomite catalyst in fluidized bed reactor were studied in the gaseous production in the one stage reactor. Problem statement: The parameters such as temperature, steam flow rate, biomass feed rate, gas flow rate for fluidization, oxygen flow rate and catalyst types were studied to produce the high gaseous products including tar … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,067 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePromotion of Coconut Shell Gasification by Steam Reforming on Nickel-DolomitePattaraporn Chaiprasert, Tharapong VitidsantBiomass gasification by the use of metallic nickel as active metal on dolomite support has been chosen as catalyst because of its activity in biomass steam gasification and tar reduction. The purpose of this study is to study the effects of critical parameters on product gas compositions such as temperature, steam to carbon ratio (S/C) and oxygen input. The results … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 8,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractMineralogy and Chemistry of Coronadite from Middle Cambrian Manganese Deposits at Wadi Dana, Southern JordanAhmad Al-Malabeh, Tayel El-HasanCoronadite was reported from the upper-most horizons of the Middle Cambrian sediments at two locations in Wadi Dana, central Wadi Araba and Jordan. The unit is composed of dolomite, limestone and shale. Geochemical investigations show appreciable variations in Mn, Pb, Fe, K and Ba contents in the coronadite between the two studied sites. Pb was found to increase downward in … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistribution of Biomicrofacies and Cement Types in the Changxing Formation (Upper Permian), Western Hubei-eastern Sichuan Provinces, South ChinaMutwakil Nafi, Xia WenchenThe Changxing formation is subdivided into lower, middle and upper parts. Four types of microfacies were recognized in the Changxing formation. They include SMF-3, SMF-6, SMF-7 and SMF-19. The Changxing Formation is composed of deep basin margin, platform margin and open restricted platform environments. The lower, middle and upper parts are dominated by deep basin margin facies, platform margin facies … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,000 accessesView PDFCite
