M. Guisnet et al., ORIGIN OF THE POSITIVE EFFECT OF COKE DEPOSITS ON THE SKELETAL ISOMERIZATION OF N-BUTENES OVER A H-FER ZEOLITE, Journal of the Chemical Society, Chemical Communications, (16), 1995, pp. 1685-1686
The curious positive effect of carbonaceous deposits on the skeletal i
somerization of n-butenes over a H-FER zeolite can be related to the d
evelopment of a new reaction mechanism involving as active sites terti
ary carbenium ions blocked in the zeolite pores.
