  1. 1. Fast pyrolysis of biomass : primary products and reaction pathways

    Författare :David Usino; Tobias Richards; Weihong Yang; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast pyrolysis; Py-GC-MS FID; Primary reactions; Cellulose; Xylan; Lignin; Birch wood; Co-pyrolysis; Mahogany; Iroko; Palm kernel shell; Biomass blend; Biomass interaction; Pretreatment; Resource Recovery; Resursåtervinning;

    Sammanfattning : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.

  3. 2. On the optimal use of industrial-generated biomass residues for polygeneration

    Författare :Marianne Salomón Popa; Torsten Fransson; Andrew Martin; Lasse Rosendahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Optimization; Palm Oil; Biomass; forest residues; Colombia; Sweden;

    Sammanfattning : Increasing energy demand as well as climate change concerns call for an analysis and optimization of energy services. Efficient use of energy resources, mitigation of environmental effects and supply an increasing demand are just some of the issues that are relevant nowadays in the energy system. LÄS MER

  4. 3. On Sustainability of Biomass for Energy and the Governance Thereof

    Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER

  5. 4. An evaluation of biodiesel policies : The case of palm oil agro-industry in Indonesia

    Författare :Fumi Harahap; Semida Silveira; Serina Ahlgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; palm oil; biodiesel; Indonesia; policy evaluation; policy coherence analysis; land allocation; sectoral policy goals; life cycle cost analysis; biodiesel cost competitiveness; biorefinery; Energy Technology; Energiteknik;

    Sammanfattning : Oil palm has flourished as an economically vital crop in Indonesia given its use in both food and non-food products (including biodiesel) for domestic and export markets. However, the expansion of oil palm plantations in Indonesia is controversial. LÄS MER

  7. 5. Exploring synergies between the palm oil industry and bioenergy production in Indonesia

    Författare :Fumi Harahap; Semida Silveira; Dilip Khatiwada; José Roberto Moreira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; palm oil industry; bioenergy; resource efficiency; sustainability; land allocation; palm oil biomass; biorefinery; policy coherence analysis; techno-economic analysis; spatio-temporal optimisation model; BeWhere Indonesia; Energy Technology; Energiteknik;

    Sammanfattning : Climate change along with increasing demand for food and fuel call for sustainable use of natural resources. One way to address these concerns is through efficient use of resources, which is also vital for the achievement of the Sustainable Development Goals and the Paris Agreement. LÄS MER
