Abstract:
1. A method of removing contaminants from a feed stream of a chemical reactor, comprising the steps of: (a) providing a plurality of discrete elements of a filtration material upstream of said chemical reactor, each said filtration element having substantially parallel first and second faces and a multi-cellular internal structure of substantially open and parallel channels extending through the filtration element from the first face to the second face; and (b) passing the feed stream through at least one layer of the filtration material, the layer of filtration material comprising a number of said filtration elements sufficient to filter the contaminant from the contaminated feed stream, provided that where said chemical reactor is a hydrotreating reactor, said feed stream is selected from the group consisting of atmospheric residuum, vacuum residuum, diesel oil, jet fuel, and kerosene.
