  1. 1. Black liquor gasification experimental stability studies of smelt components and refractory lining

    University dissertation from Umeå : Energiteknik och termisk processkemi

    Author : Mathias Råberg; Umeå universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Chemical energy engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Kemisk energiteknik;

    Abstract : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). READ MORE

  2. 2. Entrained-Flow Gasification of Black Liquor and Pyrolysis Oil Experimental and Equilibrium Modelling Studies of Catalytic Co-gasification

    University dissertation from Luleå : Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black liquor; pyrolysis oil; catalytic gasification; co-gasification; gasification; entrained-flow gasification; pilot-scale; Energy Engineering; Energiteknik;

    Abstract : The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries.

  3. 3. Black liquor gasification burner characteristics and syngas cooling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Risberg; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

  4. 4. Biofuels from Kraft Black Liquor Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    University dissertation from Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  5. 5. Entrained flow black liquor gasification detailed experiments and mathematical modelling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Per Carlsson; Luleå tekniska universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Black liquor, a by-product from the Kraft pulping process is a highly viscous fluid consisting of approximately 30% water, 30 % alkali salts and 40 % combustible material. The alkali salts originating from the pulp making process need to be recovered in order for the pulp mill to be economical and to satisfy environmental regulation. READ MORE
