Figures & data
Scheme 1. Current commercial production of linear alkylbenzenes (LABs) from benzene and linear alpha olefins using HF or AlCl3 homogeneous acid catalyst (Citation3).
Scheme 2. Production of aromatic hydrocarbons from biomass-derived furans and ethylene (Citation19–28).
Scheme 3. The new LAB production pathway from furan and linear alpha olefins over solid acid catalysts studied in this work.
Figure 1. The batch reactor system used for conducting the experiments in this work.
Figure 2. Representative gas chromatograph of reaction mixtures from Diels−Alder reaction between furan and 1-dodecene over niobic acid. The reaction temperature was 250°C, and the reaction time was 6 hours.
