Catalytic Co-Pyrolysis Process for Producing BTX Aromatics from Plastic and Biomass Feedstocks

Overview

This research program focuses on developing a catalytic co-pyrolysis process that transforms mixed plastic and biomass feedstocks into BTX aromatics—benzene, toluene, and xylene. These compounds are essential feedstocks for the chemical industry, with applications spanning chemical manufacturing, pharmaceuticals, and fuels. The approach offers a dual benefit: diverting waste streams from landfills while producing high-value chemical products.

The project combines reaction mechanism studies with systematic process optimization to maximize BTX yield. By understanding the intricate pathways governing BTX formation and fine-tuning reaction parameters, the team aims to create a commercially viable pathway for converting waste into valuable chemical resources.

Technology readiness level

This research is at an early stage, with the team conducting foundational studies. Published literature exists on co-pyrolysis of plastic and biomass, but the reaction mechanism remains unclear and process optimization for BTX production has not been well studied. The proposed 12-month research plan progresses from literature review and feedstock characterization through catalyst identification, mechanism studies, process optimization, and finally economic assessment. The technology is currently at the laboratory research stage, with validation focused on demonstrating BTX yield improvements and establishing the technical and economic feasibility of the proposed process.
