Green aromatics for a biobased economy
Research Project, 2018 – 2021

In this project we will tailor new zeolite-based catalytic materials over which green aromatics, i.e. benzene, toluene and xylenes (BTX), can be produced from pre-processed low-cost hemicellulose. We will develop on- line analysis methods composition determination of complx feed and product steams and link how selectivity towards BTX compounds depends on catalyst formulation and starting materials. We will also consider the main deactivation mechanisms and make process and techno-economic analysis to judge the competitiveness of our new catalytic processes against current processes

A number of green principles will be followed but distinctive is the principle of conserved chemical complexity. In essence it says that molecules should not be broken down to smaller building blocks for making of other larger molecules. This project is unique in that it naturally builds on this principle when five-membered rings are converted to six-memberd ring aromatics.

A cross-disciplinary approach will be adopted where basic and applied research is combined. The project is well anchored in strong research environments - catalysis at Chalmers University of Technology and bioeconomy at RISE Research Institutes of Sweden AB. This forms a unique constellation that has the potential to address the project objectives and make a difference on the international level. To strenghten utilitarian aspects we plan regular knowledge exchange with a reference group consisting of about ten forestry companies.
