Analysis of the utilization of waste catalysts from catalytic cracking reactors in oil industry

Abstract

This article covers the investigation of the catalyst waste (T.R.M 1 and T.R.M 2) produced in the reactor of oil catalytic cracking. The analysis of this waste was carried out. The properties of T.R.M 1 and T.R.M 2 were investigated and determined, the mineralogical analysis of catalyst waste was implemented, the analysis of thermal effects during the burning was performed. Catalyst waste materials investigated were used in a ceramic system (from 7% to 20% of the overall amount). It was identified that the optimal quantity of additive T.R.M 1 in formation mixes was 10%. With this amount of the additive, after the burning of formation mixes at 1050C temperature, ceramic systems with the following properties were formed: total contraction - up to 6.5%, density of the system - larger than 1847 kg/m3, compressive strength - larger than 13 MPa, water absorption - up to 11%, and effective porosity - up to 21%. The identified optimum quantity of additive T.R.M 2 in the formation mix was 20%. The obtained ceramic systems have the following parameters: total contraction - less than 10 %, density - higher than 1852 kg/m3, compressive strength - higher than 15 MPa, water absorption - less than 9%, and effective porosity - lower than 17%.
