Beschreibung
Zusammenfassung:	The present invention pertains to a micro-crystalline beohmite containing additive in a homogeneously dispersed state. Suitable additives are compounds containing elements selected from th e group of alkaline earth metals, alkaline metals, rare earth metals, transition metals, actinides, silicon, gallium, boron, titaniu m, and phosphorus. Said MCBs according to the invention may be prepared in several ways. In general, a micro-crystalline boehmite precursor and an additive are converted to a micro-crystalline boehmite containing the additive in a homogeneously dispersed state. Also claimed are shaped particles and catalyst compositions comprising the as-prepared micro-crystalline boehmite.
