Mh. Elnaas et al., PYROLYSIS OF CANMET COPROCESSING RESIDUE IN ARGON HYDROGEN PLASMA, Canadian journal of chemical engineering, 71(6), 1993, pp. 866-872
The continuous pyrolysis of CANMET coprocessing residue in argon/hydro
gen plasma was studied for the temperature range 2700 to 3670 K using
an induction plasma torch. Hydrogen was injected into the argon plasma
tailflame at molar concentrations ranging from 0 to 23%. The residue
was continuously fed in liquid form to a laboratory-scale reactor spec
ially built for the study. The residue flow rate ranged from 6 to 9 g/
min. A maximum of 10% of the residue pyrolysed with up to 90% conversi
on to gaseous hydrocarbons. The rate of residue pyrolysis and the rate
of formation of the gaseous products were found to be strongly depend
ent on the rate of heat transfer at the residue surface. The only gase
ous products detected were acetylene, ethylene and methane. Some soot
was produced, but no liquid hydrocarbons were detected.
