Thermal Depolymerization Vessels
Roben, Mfg, Inc. engineers and fabricates thermal depolymerization vessels for converting waste plastics, organic materials, and biomass into fuel oils and chemical feedstocks. Our thermal depolymerization vessels feature designs optimized for breaking polymer chains through controlled heating in oxygen-free environments.
What Are Thermal Depolymerization Vessels?
Thermal depolymerization vessels are high-temperature, high-pressure reactors where long-chain polymers and organic materials are broken down into smaller molecules through controlled heating at temperatures from 400°F to 900°F. These vessels convert waste materials into liquid fuels, chemical feedstocks, and other valuable products.

Frequently Asked Questions
What feedstocks can thermal depolymerization process?
Thermal depolymerization processes various organic feedstocks including waste plastics (PE, PP, PS), mixed plastics, tires, agricultural waste, and biomass. Different feedstocks require optimized temperature profiles and residence times for maximum conversion to liquid products.
What products are produced by thermal depolymerization?
Primary products include liquid hydrocarbons similar to diesel or fuel oil, gases (methane, ethane, propane), and solid char. Product distribution depends on feedstock composition, operating conditions, and process optimization. Liquid products can be refined or used directly as fuel.
How do thermal depolymerization vessels differ from pyrolysis?
Thermal depolymerization typically operates at higher pressures than atmospheric pyrolysis, which can improve product yields and quality. The terms are sometimes used interchangeably, but depolymerization emphasizes breaking polymer chains while pyrolysis emphasizes thermal decomposition. Process conditions are optimized for specific feedstocks and products.
