Biocarbon production from biomass via 2-stage pyrolysis

 

With LTU in charge, CES is offering an unique opportunity to perform experimental research in an empowering and modern environment in Luleå, Sweden. Travel and accomodation expenses may be possible to be covered by Erasmus or other scholarships. Please apply as soon as possible. You can either directly contact Kentaro Umeki from LTU or Simon Meilinger from TUM.

 

Objective

The main aim of this work is to investigate how various process parameters of 2-stage pyrolysis concepts affect the distribution and properties of pyrolysis products. This investigation will be carried out by laboratory experiments, product characterizations, and eventual participation in the experimental campaigns at the pilot plants of Envigas in Bureå (outside Skellefteå).

 

Background

Electrification, H₂-based reduction, and biochar use (commonly called biocarbon) are among the most promising options for the steel industry to turn fossil-free. Biocarbon is necessary for every option and hence a crucial piece of the puzzle to developing the fossil-free metallurgical industry. However, biocarbon does not exist naturally, and it should be produced from biomass pyrolysis. In many countries, large and small enterprises are developing and scaling up pyrolysis processes that can efficiently produce biocarbon and satisfy strict specifications of biocarbon properties. LTU has been, since 2015, carrying out research activities on biocarbon. Past and ongoing activities include the development of pyrolysis processes, biocarbon characterisation, and the usage of biocarbon in steel production processes.

This master thesis project is associated with the collaborative project "Maximizing carbon-rich product yield from bioresources via an innovative two-stage pyrolysis”, funded by the Strategic Innovation Program, BioInnovation (through Vinnova, the Swedish Energy Agency and Formas). Project partners are Envigas AB, Stena Recycling AB, Outokumpu Oyj, Swerim AB, and LTU. The project aims to establish an efficient method to maximize the carbon efficiency of bioresources to multiple high-value products in biocarbon production. The innovative two-stage pyrolysis (2StagePyro) is proposed, aiming to efficiently convert bioresources into bio-carbon, bio-products, and clean syngas. The biggest knowledge gap in industrializing 2StagePyro is detail knowledge of how various process parameters interact with each other and determine the distribution and properties of final products.

 

Major activities:

• Literature survey for pyrolysis and biocarbon (3 weeks)
• Set up the plans for experiments (1 weeks)
• Production of biocarbon (and bio-oil) by 2-stage pyrolysis (6 weeks)
• Characterization of biocarbon produced from each experiment (3 weeks)
• Assessment of process performance (3 weeks)
• Eventual participation in pilot plant experiments at Envigas AB (1-2 weeks)
• Writing a report (4 weeks)
