Research ArticleOpen accessIn the keywordsMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,214 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe 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 PDF Cite

Research ArticleOpen accessIn the abstractMixing Patterns and Residence Time Determination in a Bubbling Fluidized Bed SystemA. E. Ghaly, K. N. MacDonaldFluidized bed gasification can be used to convert the solar energy stored as carboneous compounds in biomass into a carbon neutral fuel with reduced emissions. Canada produces 20.57 million tonnes of wheat straw annually which could be used for green energy production. Wheat straw residue gasification has the capability of replacing 7.5 % (0.62 EJ) of Canada’s annual fossil fuel … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,115 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction and Characterization of Bio-Char from the Pyrolysis of Empty Fruit BunchesMohamad Azri Sukiran, Loh Soh Kheang, Nasrin Abu Bakar, Choo Yuen MayProblem statement: The palm oil industry generates an abundance of oil palm biomass such as the Empty Fruit Bunch (EFB), shell, frond, trunk and Palm Oil Mill Effluent (POME). For 88 million tones of Fresh Fruit Bunch (FFB) processed in 2008, the amount of oil palm biomass was more than 26 million tones. Studies about production of bio-char from oil … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 9,811 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBio-oils from Pyrolysis of Oil Palm Empty Fruit BunchesMohamad Azri Sukiran, Chow Mee Chin, Nor Kartini Abu BakarProblem Statement: The palm oil industry generates an abundance of oil palm biomass such as the mesocarp fibre, shell, empty fruit bunch (EFB), frond, trunk and palm oil mill effluent (POME). For 80 million tonnes of fresh fruit bunch (FFB) processed last year, the amount of oil palm biomass was more than 25 million tones. The objectives of this study … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 11,184 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPneumatic and Hydraulic Systems in Coal Fluidized Bed CombustorZ. O. Opafunso, I. I. Ozigis, I. A. AdetundeProblem statement: This study designed the pneumatic and hydraulic systems in coal fluidized bed combustor. These are fluidization of silica sand bed material, Air distributor, centrifugal fan, electric motor power drive and surface heat exchanger. Approach: The effects of increased gas velocity on silica sand and the resultant drag force formed the basic equations in fluidization. Air distributor was introduced … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,717 accessesView PDF Cite
