2. 1. Large-Scale Production and Use of Biomethane

   Author : Alberto Alamia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual fuel; Biomass gasification; SNG; power-to-gas; well-to-wheel; biomethane; biorefinery; GoBiGas; DFB gasifier; process simulation;

   Abstract : Societal ambitions to create an economy based on renewable resources, require the development of technologies transforming these resources into energy-carrying products and biomaterials. Dual fluidized bed (DFB) gasification represents a key technology for achieving sustainability targets, as it is a scalable and highly efficient route for the conversion of biomass. READ MORE

4. 2. Indirect gasification production of biomethane for use in heavy-duty state-of-the-art gas engines

   Author : Alberto Alamia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; well-to-wheel; biomethane; gas engines; SNG; DFB gasifier; process simulation; dual fuel; Biomass gasification;

   Abstract : The climate targets set for the European transport sector have stimulated intensiveresearch by groups in academia, the energy industry, and vehicle manufacturing in theGothenburg region into biomethane production via indirect gasification of lignocellulosebiomass and the development of advanced gas engine technologies.This work presents the results of a comprehensive study of biomethane production andutilization in heavy duty engines.

5. 3. Tar and Condensable Hydrocarbons in Indirect Gasification Systems

   Author : Mikael Israelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UCS; Tar; condensable species; DFB; HTR.; CS; CLR; SPA;

   Abstract : Biomass gasification, which is a primary process step in the production of biofuels, yields a combustible gas mixture (raw gas). This raw gas consists of a wide range of species, from permanent gases to condensable hydrocarbons, which are collectively known as tar. READ MORE

6. 4. FUEL CONVERSION IN A DUAL FLUIDIZED BED GASIFIER

   Author : Anton Larsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The present work is motivated by increasing demands and political goals to establish the commercial production of biofuels. Dual fluidized bed (DFB) gasification is a promising route for the production of biofuels through synthesis. The efficiency of biofuel production is limited by the conversion of biomass into syngas.

7. 5. Carbon Recovery in A Dual Fluidized Bed Gasifier

   Author : Sébastien Pissot; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

   Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE
