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 .
