Abstract

Apparatuses and methods of use are provided for a lobular catalyst for use in processes featuring water at high pressures and high temperatures, including in supercritical or near supercritical water conditions. The lobular catalyst structure features a shaped, plate-like structure extending along the reactor length with a high surface area. The lobular catalyst structure is fixed in place and mounted within a high temperature and high pressure reactor. The catalyst includes a catalytically active component, which can be a transition metal. The catalyst can be used in high pressure and high temperature processes, including in supercritical or near supercritical water processes, to improve heavy oil upgrading and hydrocarbon conversion in chemical processes.
