Synthesis of Polyethylene Terephthalate (PET) Polyster Fiber from Bio Based Ethanol in a Noble Catalytic Conversion Process in a Fixed Bed Reactor
Author(s): Daniel Tasew* and Nurlign Tefera
The catalytic conversion of ethanol to Polyethylene Terephthalate (PET) represents a significant advancement in sustainable polymer production, utilizing renewable feedstock’s and pioneering catalytic methodologies. This review examines the intricate multi-step catalytic pathways essential for converting bio-derived ethanol into PET, with a focus on recent innovations in eco-friendly catalyst development and enhancing catalytic efficiency, specifically within fixed bed reactors. The process comprises several key stages: Dehydration of ethanol to ethylene, oxidation of ethylene to Ethylene Glycol (EG) and polymerization of EG with Terephthalic Acid (TPA) to synthesize PET. Each stage presents distinct challenges and opportunities for catalyst improvement and process refinement within the fixed bed reactor configuration. Initially, the dehydration of ethanol to ethylene in a fixed.. View More»
