Abstract
The present invention relates to a catalyst composition in the form of a capsule, having walls made of solid material which define a closed volume which contains a liquid phase comprising at least one ionic liquid of formula Q+A−, wherein Q+ is an organic cation and A− is an anion, and in which a Brönsted acid HB is dissolved.

A catalyst composition in the form of a capsule, having walls made of solid material which define a closed volume which contains a liquid phase comprising at least one ionic liquid of formula Q+A−, wherein Q+ is an organic cation and A− is an anion, and in which a Brönsted acid HB is dissolved.
An acid catalysis process, especially chosen from processes of alkylation of aromatic hydrocarbons, oligomerization of olefins, dimerization of isobutene, isomerization of n-olefins to iso-olefins, isomerization of n-paraffins to iso-paraffins, and alkylation of isobutane by olefins, characterized in that said process uses a catalyst composition in the form of a capsule having walls of solid material which define a closed volume which contains a liquid phase comprising at least one ionic liquid of formula Q+A−, Q+ being an organic cation and A− being an anion, and in which a Brönsted acid HB is dissolved.
