A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

A heat-transforming ceramic roasting cylinder and a coffee bean roaster using the same are provided. The ceramic roasting cylinder is made by grinding and mixing ball clay, kaolin clay, mullite, spodumene, and an energy ceramic material into a clay blank; molding the clay blank into ceramic green bodies; and sintering the ceramic green bodies at 12501320 C. for 1824 hours. The ceramic roasting cylinder has an internal roasting space where coffee beans are loaded. The ceramic roasting cylinder also has evenly distributed capillary pores through which heat can circulate to induce the energy ceramic material in the roasting cylinder to release negative ions and far-infrared rays. The far-infrared rays can reduce the van der Waals forces between the oil molecules in the coffee beans instantly, splitting large oil molecules into smaller ones, ensuring the oil in the beans are released sufficiently, evenly, and rapidly to the vicinity of the bean surface.
