Research ArticleOpen accessIn the keywordsMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part II: Characteristic Velocity Profiles, Critical Loading and Binary CorrelationsV. S. Chok, A. Gorin, H. B. ChuaProblem statement: In Part I of this research, the main features of the fluidization behavior and characteristic velocities had been reported. Approach: In the present research, the mixtures characteristic velocity profiles for various sand sizes, palm shell sizes and weight percents were presented. It was recognized that there are instances where the characteristic values remain nearly unchanged from its pure … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,423 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCFD-PBE Modelling and Simulation of Enzymatic Hydrolysis of Cellulose in a Stirred TankNorazaliza Mohd Jamil, Qi WangRenewable energy or biofuel from lignocellulosic biomass is an alternative way to replace the depleting fossil fuels. The production cost can be reduced by increasing the concentration of biomass particles. However, lignocellulosic biomass is a suspension of natural fibres and processing at high solid concentration is a challenging task because it will affect the mixing quality between the enzyme and … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 25 Oct 2016 · 7,999 accessesView PDF Cite

Review ArticleOpen accessIn the abstractEffects of Intermittent Artificial Circulation in Summer Months on Chlorophyll a Concentration in a Small Eutrophic ImpoundmentAnusha Balangoda, Shafiqur Rahman, G. PadmanabhanImpact of artificial circulation on total algal biomass (as chlorophyll a integrated over depth) in a small eutrophic impoundment in the Northern Great Plains, was monitored over three consecutive summers. Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and non-aerated conditions at four sampling locations. Aeration destratified the water column, which resulted in … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 14 Nov 2015 · 7,303 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment and Evaluation of a Low-Density Biomass Feeding System for Fluidized Bed GasifiersA. E. Ghaly, A. Ergudenler, S. Alsuhaibani, V. V. RamakrishnanFor efficient operation of a biomass gasifier, the biomass material must be fed continuously to the system. A feeding system for chopped straw and rice husk was designed, constructed and evaluated. It consisted of: a frame, a hopper, an auger, two agitators, a drive system and a power unit. Initial testing showed that wheat straw and rice husk, being highly … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 7 Nov 2013 · 8,039 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 abstractMinimum 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 abstractDensity Equation of Bio-Coal Briquettes and Quantity of Maize Cob in Phitsanulok, ThailandPatomsok WilaiponOne of the most important crops in Phitsanulok, a province in Northern Thailand, is maize. Base on the calculation, the quantity of maize cob produced in this region was approximately 220 kton year-1. The net heating value of maize cob was found to be 14.2 MJ kg-1. Therefore, the total energy over 874 TJ year-1 can be obtained from this … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,891 accessesView PDF Cite
