Abstract
The present disclosure relates to a catalytic reactor for cracking wax of pyrolysis oil generated from waste plastic pyrolysis emulsification process, a catalytic composition and a production method thereof. Particularly, the present disclosure relates to a catalytic composition for cracking wax, including: a support that includes zeolite containing silicon oxide and aluminum oxide, and silica; and an active metal that includes iron and zinc, and is immersed in the support, thereby cracking carbides with C14 or more included in wax of pyrolysis oil generated during waste plastic emulsification process.
Claims7
As a catalytic reactor for cracking wax in a process for pyrolyzing waste plastics, a catalytic reactor for cracking wax in a waste plastic pyrolysis process comprising:
- a main body portion that is formed in a cylindrical shape;
- a pyrolysis oil inlet, which is provided on one side of the main body portion and allows pyrolysis oil gas in an oil vapor state generated as passing through a pyrolysis reaction furnace to be introduced;
- a catalyst bed portion, which is provided inside the main body portion and allows a wax absorption catalyst to be filled inside and reform wax inside the pyrolysis oil;
- an external heating portion that is integrally installed on the external surface of the main body portion and supplies thermal energy to the catalyst bed portion;
- a pyrolysis oil outlet, which is provided on another side of the main body portion and allows the wax-reformed pyrolysis oil to be discharged;
- a lower cone having a diameter gradually decreasing downwardly at a lower end of the main body portion and having the pyrolysis oil outlet;
- an upper cone having a diameter gradually decreasing upwardly at an upper end of the main body portion ad having the pyrolysis oil inlet;
- and
- a control portion that controls temperature of the external heating portion to adjust the internal temperature of the catalytic reactor, wherein
- at the beginning of pyrolysis operation, water vapor generated by heating the water contained in the waste plastic is supplied to the inside of the catalytic reactor, and
- a catalyst reactivation process is carried out, in which the water vapor passes through the catalyst bed portion and removes carbon deposited on the surface of the catalyst.
