Continuous flow hydroprocessing of waste plastics using ionic liquid catalyst
This study demonstrates a novel continuous flow hydroprocessing method for converting waste plastics into diesel-like fuel. Utilizing a Pd/SBA-15 catalyst functionalized with 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIM NTf2) ionic liquid, the process achieves efficient conversion at a significantly lower temperature (180 °C) compared to conventional methods. The resulting fuel, HMWPO, exhibits physicochemical properties and combustion performance highly comparable to commercial diesel, offering a sustainable and energy-efficient solution for plastic waste valorization.

Case Study: Scaling Waste Plastic Hydroprocessing
Summary: A major petrochemical company sought to integrate a sustainable solution for its plastic waste streams, aiming to produce marketable fuels while reducing environmental footprint. Traditional pyrolysis offered low-grade oils, and existing hydroprocessing technologies were energy-intensive.
Challenge: The primary challenge was finding a cost-effective and energy-efficient method to upgrade mixed plastic pyrolysis oil (MWPO) into high-quality diesel-like fuel suitable for existing infrastructure and engines, without significant operational changes.
Solution: Implementing the continuous flow hydroprocessing system with the novel Pd/SBA-15/BMIM NTf2 ionic liquid catalyst addressed these challenges. The low reaction temperature (180°C) drastically cut energy costs, and the continuous flow design allowed for high throughput and consistent product quality. The catalyst's enhanced selectivity minimized by-product formation.
Result: The company successfully converted 95% of its MWPO into HMWPO, achieving a fuel quality highly comparable to commercial diesel (95% similarity in composition). This led to an estimated 30% reduction in operational energy costs for upgrading and opened new revenue streams from waste valorization, significantly improving their sustainability metrics.
