  1. 11. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Rydgård; [2020]
    Keywords : lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. READ MORE
