Abstract
By use of a slurry mixture described herein, catalyst particles or other similar particles can be transferred over considerable temperature differential without breaking or crumbling. By selecting a carrier fluid with a combination of high critical temperature and low critical pressure relative to the conditions under which the particles will function, a slurry mixture is provided which protects the contained particles against breakage.
