摘要： A method of removing a catalyst, particularly Raney nickel, from a catalytic reaction product, particularly a hydrogenation reaction product, by passing the catalytic reaction product containing the solid catalyst through a hollow tubular filter medium which comprises a nonwoven web of fibers, has a tapered pore distribution such that the pore size of the filter medium decreases in the direction of normal fluid flow, and is backwashable.
