The present disclosure relates to a method of regenerating an at least partially deactivated catalyst, preferably an aromatic alkylation or transalkylation catalyst, comprising a molecular sieve. The first conveyor has a belt for transporting paper disposed at a first elevation. The securing plate preferably includes two locking members each of which is biased toward a first position in which the respective locking members prevent the securing plate from disengaging from a closed position with respect to the support frame. The light emission chip is electrically connected to the circuit board. The additional controllers may be paddle levers and may replicate the functions of one or more of the controls located on the front or top of the controller. 1 mm, each microprism comprising three mirror facets, a first and second one of the mirror facets as well as a third one and the second mirror facet extending at right angles to each other, while the first and third mirror facets enclose an angle of greater than 90 with each other, and a base facet of the microprisms projected onto a plane forming an irregular hexagon.
