Studying the properties of the spent catalyst cracking of petroleum hydrocarbons

In this paper, we studied the properties of the source and spent zeolite catalyst cracking of petroleum hydrocarbons. A comparative analysis showed that in the process of cracking a change in the structure and elemental composition of the catalyst. Determined sorption capacity of the catalyst of copper ions and iron, surface area and the source of spent catalyst. The findings suggest that the possibility of using spent catalyst for binding, limiting the mobility of heavy metals in soil and sewage sludge.
