摘要： A high-activity catalyst used to prepare polyethylene and a method of preparing polyolefin using the same are provided. When preparing the high-activity catalyst, a specific halogenated hydrocarbon is added to control the electrical properties of catalytic active sites and provide a large steric space around the catalytic active sites. Therefore, polyolefin with a wide range of molecular weights can be synthesized using the catalyst.

摘要： The present invention provides a method and apparatus for preparing vinyl chloride in which reaction yield is improved and problems caused by coke generated during reactions can be solved. According to an aspect of the present invention, there is provided a method of preparing vinyl chloride comprising: supplying chlorine gas and ethane to an ethane chlorination reaction region disposed in a lower portion of a pyrolysis reactor in which solid particles exist; performing an ethane chlorination reaction by contacting the chlorine gas and ethane with solid particles such that a product of the ethane chlorination reaction and the solid particles rise toward an upper portion of the pyrolysis reactor at the same time, and depositing coke produced during the ethane chlorination reaction on the solid particles; performing a pyrolysis reaction in a pyrolysis reaction region disposed in an upper portion of the pyrolysis reactor by contacting a product of the ethane chlorination reaction with the solid particles such that the product of the ethane chlorination reaction and the solid particles rise up at the same time, and depositing coke produced during the pyrolysis reaction on the solid particles; separating solid particles obtained from the pyrolysis reaction and a product of the pyrolysis reaction in a separator; moving the separated solid particles to a regeneration reactor, and then burning coke deposited on the solid particles to regenerate the solid particles; and resupplying the regenerated solid particles to the pyrolysis reactor. According to another aspect of the present invention, there is provided an apparatus of preparing vinyl chloride comprising: a pyrolysis reactor comprising an ethane chlorination reaction region in a lower portion thereof and a pyrolysis reaction region in an upper portion thereof; a separator that separates a product of a pyrolysis reaction and solid particles; and a regeneration reactor that regenerates the separated solid particles by burning. When vinyl chloride is prepared using the method and apparatus according to the present invention, reaction yield is improved, and coke production and following coke accumulation in reactor can be inhibited.
