Techno-economic Assessment of BTX Production from Bio-based Waste Feedstocks via Integrated Cascading Catalytic Pyrolysis
Short Introductive summary
While sugar-based polymers are currently being commercialized to displace fossil polymers, bio-aromatics are not yet produced on any commercial scale. The BioBTX process is a promising pathway to produce the chemicals benzene, toluene and xylenes (BTX). The current base case produces BTX from mixed waste plastics via pyrolysis with integrated catalytic upgrading. Feedstocks for alternative production routes include Used cooking oil (UCO) and lignin combined with pre-treatment or post-processing of char. This research aims determine the techno-economic performance of five novel potential bio-based BTX production pathways, with an added NetZero carbon emission constraint. Based on mass and energy balances, key technical and economic parameters were calculated via a cash flow model. A sensitivity analysis was conducted to identify key cost drivers and tipping points.
