摘要：
The present invention relates to a process for the preparation of zeolitic catalysts of the MFI type in spheroidal form.The process consists in emulsifying and consolidating in paraffinic hydrocarbons, in the presence of a non-ionic surface-active agent or a suitable combination of a non-ionic surface-active agent and a cationic surface-active agent, a dispersion of particles of zeolitic material of the MFI type in a silica sol.
