Class Information
Number: 502/48
Name: Catalyst, solid sorbent, or support therefor: product or process of making > Regenerating or rehabilitating catalyst or sorbent > Gas or vapor treating > Treating with free oxygen containing gas > Moving bed (e.g., vertically or horizontally, etc., moving bulk material) > Generally transverse (i.e., lateral) flow of oxygen containing gas relative to material
Description: Process in which the treating fluid travel is normal (at a right angle) to the direction of catalyst or sorbent feed.
