ABSTRACT:
Improved apparatus for carrying out catalytic chemical conversion and restoring the catalytic activity of solid particles previously used to promote chemical conversion involve improved devices to at least partially separate solid particles-vapor mixtures. These improved devices include, for example, properly positioned arresting vanes, flow reversal systems and/or plates, and provide for reduced attrition of the solid catalyst particles.
Improved methods employing such apparatus are also disclosed.
