PYROLYSIS OF METHYL CHLORIDE ON CATALYST SAPO-34/Al<sub>2</sub>O<sub>3</sub> IN THE STATIONARY BED AND THE FLUIDIZED BED REACTOR
The process of pyrolysis of methyl chloride with the use of a silicoaluminophosphate catalyst granulated with Al2O3, the content of which varied in a range of 40–60 weight %, is investigated. The synthesized catalyst SAPO-34/Al2O3 in a mass ratio 60:40 is performed in the form of tablets for work in...

| description | The process of pyrolysis of methyl chloride with the use of a silicoaluminophosphate catalyst granulated with Al2O3, the content of which varied in a range of 40–60 weight %, is investigated. The synthesized catalyst SAPO-34/Al2O3 in a mass ratio 60:40 is performed in the form of tablets for work in a stationary bed, as well as in a microsphere for the fluidized bed. The basic physical and chemical properties of the tested catalysts are determined. Comparison of the behaviour of the synthesized catalysts in the process of methyl chloride pyrolysis in the stationary bed and the fluidized bed is carried out. The process of methyl chloride pyrolysis on the fluidized bed microsphere catalyst is investigated. Temperature was varied in a range of 425–450ºС, the feed rate (WHSV, equivalent to the mass of methyl chloride) was in the range of 0.8–4.8 h−1 , time on stream (TOS) was 2 h. The basic technological parameters of the process providing conversion of methyl chloride not below 70% and selectivity of ethylene formation not lower than 45% are determined. |
