  1. 1. Study of the Performance of Peat Moss Pyrolysis

    University essay from KTH/Materialens processteknologi

    Author : Yuming Wen; [2019]
    Keywords : peat moss; pyrolysis; bio-acids;

    Abstract : Peat moss, also called sphagnum, has become a big problem in many countries such as China and Sweden due to its high green-house gas emission from chemical and biological degradation. In this work, the performance of peat moss pyrolysis has been studied, to investigate the potential of application of peat moss pyrolysis on fuel and chemical production. READ MORE

  2. 2. Is it possible to reconstruct local pre-sence of pine on bogs during the Ho-locene based on pollen data? : a study based on surface and stratigraphical samples from three bogs in southern Sweden

    Author : Isabelle Timms Eliasson; [2014]
    Keywords : southern Sweden; vegetation cover; bog; Pinus; pollen; Earth and Environmental Sciences;

    Abstract : Horizons rich in subfossil stumps and roots of Scots pine (Pinus sylvestris) are frequently found in stratigraphies of northern European peatlands, providing clear evidence of Holocene periods with favourable conditions for bog-pine growth. The pines could only grow when bog-surface wetness was sufficiently low, and the presence of their remains is therefore a good indicator of past climatic conditions, mainly precipitation. READ MORE

  3. 3. Warming alters photosynthetic rates of sub-boreal peatland vegetation

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Arvo Aljaste; [2011]
    Keywords : Peatlands; CO2 uptake; Climate change; microtopography;

    Abstract : Boreal peatlands are important in the global carbon cycle. Despite coveringonly 3% of the global land area, peatlands store approximately one third of all soilcarbon. Temperature is one of the major drivers in peatland carbon cycling as itaffects both plant production and CO2 fluxes from soils. READ MORE
