Abstract
Arrangement for transfer of particulate material by flow under gravitational force from an upper contact zone 28 in which they are brought in contact with a first radially flowing gas stream to a lower zone 66 in which they are brought into contact with another upward flowing gas stream. The arrangement includes an essentially annular transition zone 44 containing particles, which connects the upper and lower zones 28, 66. The vertical height of transition zone 44 effectively prevents the second gas stream from coming into contact with the particulate material in upper zone 28. In a proposed variant in the form of a catalyst regenerator a sample of catalyst particles can be taken for testing of carbon content in transitional zone 44 to determine the extent to which removal of carbon from the particles is sufficiently complete in an upper regenerator bed 30 with radial flow through contact with the first gas stream that has a relatively low oxygen content. Sampling can occur during flow even if another gas stream, like a halogenation gas relatively rich in oxygen passes upward through the catalyst in the lower zone 66. <IMAGE>
