  1. 1. Magnetic Activated Carbon Production from Lignin and Ferrous Salts : Process Modification for Enhanced Phosphate Adsorption from Aqueous Solutions

    University essay from KTH/Materialvetenskap

    Author : Zhaoran Zheng; [2020]
    Keywords : Magnetic bio-activated carbon; phosphate adsorption; lignin; steam activation.; Magnetiskt bioaktiverat kol; fosfatadsorption; lignin; ångaktivering;

    Abstract : The treatment and control of superfluous aqueous phosphate is a critical task in environmental management. Magnetic bio-activated carbon is a good adsorbent for physical adsorption methods with several environmental and economic advantages. READ MORE

  2. 2. Waste-to-Energy : A study on Reaction Kinetics of Tropical Wood Sawdust

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bertrand Asongwe Tita; [2016]
    Keywords : Tropical biomass; Thermo-gravimetric Analysis TGA ; reaction kinetics; pyrolysis;

    Abstract : The reaction kinetics of Iroko and Mahogany were studied using TGA. The pyrolysis process was achieved using six different heating rates of 2,5,8,12,15 and 20˚C. A 15˚C/min heating rate was used for gasification in steam at different temperatures while varying the concentrations of nitrogen and steam in the process. READ MORE

  3. 3. Characterization of activated carbon produced from coffee residues by chemical and physical activation

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Javier Sanchez; [2011]
    Keywords : activated carbon; coffee residues; chemical acivation; physical activation; surface characteristics;

    Abstract : Activated carbons are one of the most used adsorbents with lots of applications in many sectors. Activated carbons can be produced from lignocellulosic materials with a large content of carbon. Coffee is the second trade most consumed all over the world; hence their residues can be treated in order to give a value. READ MORE

  4. 4. Investigation of Conditions for Activation of Rupture Disk in BWR Containment Filtering System

    University essay from KTH/Kärnkraftssäkerhet

    Author : Guillem Beltran Arroyos; [2011]
    Keywords : GOTHIC software; rupture disk; large LOCA;

    Abstract : Due to the Three Mile Island accident in 1979 the Swedish government took the decision in 1986 to impose a pressure relief system for Swedish BWR’s which prevents containment overpressure in case of LOCA. This pressure relief system consists of a rupture disks in two different systems, non-filtered system 361 and filtered system 362. READ MORE

  5. 5. Dynamic modeling of a solid oxide fuel cell system in Modelica

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Daniel Andersson; Erik Åberg; [2010]
    Keywords : Solid oxide fuel cell Modelica simulation; Technology and Engineering;

    Abstract : In this study a dynamic model of a solid oxide fuel cell system has been developed. The work has been conducted in cooperation with Modelon AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. READ MORE
