Plastic Pyrolysis Oil Upgrading Catalysts and Adsorbents Market to Reach USD 2.64 Billion by 2034 as Chemical Recycling Scales

According to a new report published by OG Analysis, the Plastic Pyrolysis Oil Upgrading Catalysts and Adsorbents Market is valued at USD 520 million in 2026 and is projected to reach USD 2,636.9 million by 2034, expanding at a CAGR of 22.5%. Demand is driven by chemical recycling investment, recycled-content targets and the need to purify plastic-derived pyrolysis oil for steam crackers and refinery processing.

Market Overview

Plastic pyrolysis oil upgrading catalysts and adsorbents remove chlorine, sulfur, nitrogen, oxygenates, metals and silicon while stabilizing waste-plastic-derived hydrocarbon streams. Hydrotreating and hydrocracking catalysts, zeolites, guard-bed adsorbents and specialty purification media help operators meet stringent refinery and petrochemical feedstock specifications. Adoption is accelerating as advanced recycling plants move from demonstration to commercial scale and integrate with steam crackers. Challenges include variable feedstock quality, catalyst deactivation, hydrogen demand, contamination management and qualification costs.
