  1. 1. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hjörtur Brynjarsson; [2021]
    Nyckelord :Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

  3. 2. Propellant Feeding System of a Liquid Rocket With Multiple Engines

    Master-uppsats, KTH/Rymdteknik

    Författare :Valentin Miquel; [2020]
    Nyckelord :Multiengine Feeding System;

    Sammanfattning : Multiengine first stages are the new trend in recent rockets. Reusability and an oxygen/methane based engine complete this picture. ArianeGroup wants to develop its own rocket following these principles. This thesis presents the study of the feeding system for a seven Prometheus engine rocket. LÄS MER

  4. 3. Våm-pH hos mjölkkor : jämförelse av mättekniker och pH-förändring i samband med foderintag

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Veronica Furenbäck; [2019]
    Nyckelord :nätmagens pH; våmacidos; SARA; LRCpH; eBolus; buffring; salivflödeshastighet; tuggaktivitet; idissling; peNDF; partikellängd; sortering;

    Sammanfattning : Våmmens pH hos mjölkkor varierar under dygnet och mikroberna i våmmen behöver ett pH mellan 6-6,5 för att fungera optimalt. Normalt hålls våm-pH stabilt genom att kon absorberar flyktiga fettsyror (VFA) till blodet och den viktigaste mekanismen är saliven vilket har en buffringsförmåga då den innehåller bikarbonat och vätefosfatjoner.

  5. 4. Catalytic Upgrading of Fast Pyrolysis Bio-oil Using Zeolites

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Elena Wikberg; [2019]
    Nyckelord :;

    Sammanfattning : Fast pyrolysis bio-oil is considered as a possible source for production of liquid bio-fuels and bio-chemicals enabling the necessary transition to a renewable energy system. In this Master’s thesis work the upgrading of fast pyrolysis bio-oils with Fluid Catalytic Cracking (FCC) conversion process at industrially relevant conditions is studied using Fluid Catalytic Cracking Micro Activity Test (FCC MAT) unit at RISE ETC in Piteå, Sweden.
