Abstract:
Disclosed are a catalyst for dehydrogenating a paraffinic hydrocarbon and a method of preparing the same, wherein the catalyst is configured such that a sponge-type alumina support having 3D meso/macro pores is directly impregnated with an active metal, thus decreasing the diffusion resistance of a material, realizing structural stability, and maximizing the distribution of the active metal in the support, thereby significantly increasing olefin conversion and selectivity. In this catalyst, the sponge-type alumina support is directly impregnated with the active metal to thus form an active metal layer inside the support having 3D meso/macro pores that are interconnected to each other.
Abstract:
Catalyst composition useful in the catalytic dewaxing of a waxy hydrocarbon feedstock which catalyst composition includes a mixture of zeolite EU-2 and titania and may further include a noble metal. The zeolite EU-2 has a molar bulk ratio of silica-to-alumina (SAR) of greater than 100:1. The zeolite or mixture may have been dealuminated such as by acid leaching using a fluorosilicate salt or by steam treating.
Abstract:
The hydrotreating catalyst of the present invention is a hydrotreating catalyst including a catalyst support including an amorphous composite metal oxide having solid acidity, and at least one active metal supported by the catalyst support and selected from noble metals of Group 8 to Group 10 in the periodic table, wherein the hydrotreating catalyst contains a carbonaceous substance including a carbon atom, and the content of the carbonaceous substance in the hydrotreating catalyst is 0.05 to 1% by mass in terms of the carbon atom.
Abstract:
A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component in an upstream catalyst bed thereby producing an intermediate hydrocarbon mixture containing olefins and C 21+ normal paraffins. The intermediate hydrocarbon mixture is subsequently contacted with a hydroisomerization catalyst and an olefin saturation catalyst, thereby resulting in a product containing no greater than about 25 wt% olefins and containing no greater than about 5 wt% C 21+ normal paraffins. The hydroisomerization and olefin saturation catalysts may be in separate beds or mixed in a single bed downstream of the synthesis gas conversion catalyst.
