Abstract:
A method for continuously applying seal material to monolithic catalyst structures, each structure having a lateral surface and two end surfaces, comprising:applying temporary sealing to the end surfaces of each of the catalytic structures; aligning the catalyst structures end to end to form a column; moving the column of catalyst structures a discrete distance so that one of the catalyst structures moves into an extrusion chamber; removing enough air from the extrusion chamber to ensure that the available space within the chamber will be filled with seal material; supplying seal material to the extrusion chamber effective to coat the structure; moving the column of catalyst structures a discrete distance effective to push another structure into the chamber and to remove the structure just coated from the chamber; and removing the temporary sealing from the end surfaces of the coated structure.
