Abstract :
Petrochemical industry is a branch of chemical industry that uses raw materials in the form of oil and gas to produce industrial products. Various chemical or physical processes are used to produce optimal products. Among the key and strategic products in the petrochemical industry, we can mention propylene and polypropylene. Propane dehydrogenation (PDH-Propane dehydrogenation) is a highly efficient catalytic technology that is used to convert propane into propylene and finally polypropylene, and it has received wide attention today. Propylene is one of the intermediate products used in many petrochemical applications, such as the production of polypropylene resins, acrylic acids, propylene glycol, acrylonitrile, cumene/phenol and other industrial products. Usually, propylene is obtained by cracking naphtha derived from oil and is a byproduct of ethylene production, but currently, in order to produce propylene more widely, propane dehydrogenation process is used. With the increase in global demand for propylene in the automotive sector, the production of bottle caps, fabrics, packaging materials and the production of chemicals, the petrochemical industry is inevitably moving towards the targeted production of propylene. This goal will be achieved mainly through propane dehydrogenation, where propane is selectively hydrogenated (removal of hydrogen from the propane stream). The results of this research, in addition to identifying the most suitable method of producing propylene from propane (Oleflex or Catofin), indicate that the implementation of PDH projects in the country, in addition to meeting the needs of domestic industries, completing the chains It will also bring value to the country's petrochemical industry.
