- Compositions C 6, C 7 and C 8 tested under the same conditions show the same way a sharp decrease in clearance of H 2 S with respect to the composition T 2.
- the releases of H 2 S are, on the other hand, much more important in the process for preparing the composition T 3 (there is not a decrease in the amounts of hydrogen sulphide, but an increase with respect to T 2 ).
