What is Propane Dehydrogenation and How Does It Work?
Propane Dehydrogenation (PDH) is an industrial chemical process used to convert propane (C₃H₈) into propylene (C₃H₆) by removing hydrogen atoms. Propylene is a key building block in the petrochemical industry, especially in the production of polypropylene plastics, acrylonitrile, and other chemicals.
How It Works:
- Feedstock Preparation
Propane gas is preheated and purified to remove contaminants that could damage the catalyst or reduce efficiency. - Dehydrogenation Reaction
The propane enters a reactor where it is exposed to high temperatures (500–700°C) and passes over a metal-based catalyst, usually platinum or chromium oxide.
The chemical reaction:
C₃H₈ → C₃H₆ + H₂
This is an endothermic process (requires heat) and is typically carried out under low pressure to shift the equilibrium toward propylene production. - Hydrogen Removal
To drive the reaction forward, hydrogen is continuously removed from the reaction chamber, often using a vacuum pump or selective membrane system. - Separation and Purification
The resulting gas mixture contains propylene, hydrogen, unreacted propane, and by-products. This mixture is cooled and separated using distillation and absorption units to isolate high-purity propylene.
