PRODUCTION METHOD OF AMORPHOUS SILICA-ALUMINA CATALYST FROM COAL FLY ASH FOR CATALYTIC PYROLYSIS OF WASTE PLASTICS

摘要

The present invention relates to a method for producing an amorphous silica alumina catalyst from coal fly ash, and more particularly, to a method for preparing an amorphous silica alumina catalyst that can be used in waste plastic pyrolysis oilification process using coal fly ash and alkali. On the other hand, the present invention includes a method of obtaining an oil from waste plastic by using the amorphous silica alumina catalyst obtained by the method for preparing an amorphous silica alumina catalyst obtained from coal fly ash in a waste plastic pyrolysis oilification process.;The present invention can be used to prepare a low cost amorphous silica alumina catalyst from coal fly ash and the amorphous silica alumina catalyst prepared by the above method in waste plastic pyrolysis oilification process to obtain light oil level pyrolysis oil from waste plastic.;The present invention can reduce the production cost of the catalyst required for waste plastic pyrolysis process by using an amorphous silica alumina catalyst prepared from coal fly ash as waste as a catalyst used in the oilification process of pyrolysis of waste plastic. In addition, the amorphous silica alumina catalyst prepared according to the present invention can also help to prevent environmental pollution by manufacturing using coal fly ash as waste.
