摘要

TUD-1, a new family of mesoporous materials, is a three-dimensional amorphous structure of random, interconnecting pores. The original emphasis was on the silica version, which has since been extended to about 20 chemical variants (e.g., Al, Al-Si, Ti-Si, etc.). Multimetallic oxides have been made so the catalytic opportunities are almost endless.rnIn principle, these "mesoporous" materials (i.e., pore diameters from 2 to 20 nm) should be useful for processing high molecular weight materials, such as petroleum residua, lubricants, etc. If synthesized with high surface areas, the resultant catalysts could have significant benefit for high conversion, fast reactions where mass transfer plays a critical role. In addition to efficiently transporting reactants into the active sites, mesopores enable the products to leave the active sites and thereby reduce unwanted side reactions.rnSince discovery of the famous M41s family of crystalline mesoporous materials, a worldwide effort has been made on synthesis, characterization, and catalytic evaluation. Many research programs focused on transforming MCM-41 into active and stable forms, but with medium success. Many scientists since have refocused attention towards other mesoporous materials.rnSince mesoporous catalysts held promise for hydrocarbon chemistry such as refining and petrochemical, Lummus initiated a joint research project with the Delft University of Technology. From this collaboration came the discovery of a new mesoporous material, named TUD-1. The key common properties of TUD-1 are:rn1. Tunable porosity and pore sizern2. High surface arearn3. Excellent stabilityrn4. Random, three-dimensional interconnecting poresrnVariants of TUD-1 have been shown to be effective for a wide range of reactions, some of which include alkylation, cracking, epoxidation, hydrogenation, hydrogenolysis, etc. One exciting area is the use of zeolites embedded in TUD-1 to give a synergistic performance for various probe reactions.
