  1. 1. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    University dissertation from Karlstad : Karlstads universitet

    Author : Ida Larsson; Karlstads universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. READ MORE

  2. 2. Some aspects on the reduction of olivine pellets in laboratory scale and in an experimental blast furnace

    University dissertation from Stockholm : Materialvetenskap

    Author : Jerker Sterneland; KTH.; [2002]
    Keywords : Olivine; pellets; pellet testing; reduction softening melting; MPBO; blast furnace; reduction; quenching; dissection; coating; sticking; coated pellets;

    Abstract : The reduction behaviour of the olivine iron ore pellet MPBOwas studied in laboratory scale at KTH as well as in the LKABexperimental blast furnace. Initially, a newreduction-under-load, or so-called reduction/softening/melting,test equipment was developed. READ MORE

  3. 3. Diffusion Controlled Drug Release from Slurry Formed, Porous, Organic and Clay-derived Pellets

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Jämstorp Berg; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion; Drug delivery; Antithrombotic drugs; Highly potent opioids; Modeling; Clays; Polymers; Pellets; Beads; Materialvetenskap; Materials Science;

    Abstract : Coronary artery disease and chronic pain are serious health issues that cause severe discomfort and suffering in society today. Antithrombotic agents and highly potent analgesics play a critical role in improving the recovery process for patients being treated for these diseases. READ MORE

  5. 5. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis

    University dissertation from Martin Andersson, Technical Analytical Chemistry, Lund University, P.O.Box 124, S-221 00 Lund, Sweden

    Author : Martin Andersson; Lund University.; Lunds universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; PAC; NIR; chemometrics; moving samples; information depth; release rate; image analysis; near infrared; process analytical chemistry; thickness; coating; film; tablets; Pellets; granules; Analytical chemistry; Analytisk kemi;

    Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE
