If metals are used when biomass undergoes gasification, the process can be more effective. For example, it may be possible to get rid of tar at lower temperatures. Tar risks destroying the equipment and reducing efficiency. Abas Mohsenzadeh at the University of Borås will examine how metals affect the process.

One of the major issues in the biomass gasification technology is how to efficiently deal with biomass tars which cause difficulties in the downstream processes. The tars can be reduced by metal catalyzed cracking processes but todays processes require a rather high temperature which is not favorable from an energy perspective.

The main objective of this project is to lay the foundation for efficient catalysts for tar cracking that operates at low temperature. Using quantum mechanics simulations, the electronic structures and charge distribution of key intermediates that represent the tar composition will be analyzed to elucidate the chemistry of materials behind catalytic reactions to reveal the most important interactions.
