A fixed bed, radial flow reforming reactor having an inner catalyst zone between an inlet fluid zone and an outlet fluid zone. The catalyst zone is separated into two concentric, annular zones, a first annular zone having a first solid particle material having a first catalytic activity for reforming hydrocarbons into the catalyst zone, and, a second annular zone having a second solid particle material having a second catalytic activity for reforming hydrocarbons into the catalyst zone, wherein the second catalytic activity is different. One of the materials may be inert. A divider may be used to separate the two annular zones.

A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.

The present invention pertains to a radial flow adsorption vessel comprising a cylindrical outer shell and at least one cylindrical porous wall disposed co-axially inside the shell, wherein inside the shell one or more fluid permeable screens are rigidly connected to the at least one cylindrical porous wall, by a multitude of separate standoff elements so that the screen has a cylindrical shape co-axial to the shell, and to an adsorption process using the radial flow adsorption vessel.
