Refining catalysts with high activity and stability

Product Introduction:

Refining catalysts with high activity and stability are used to remove compounds of sulphur and nitrogen from oil and to convert aromatics to cycloalkanes. The active component is a composite oxide or sulphide of metals such as key, drill, tungsten and phosphorus.

AM-DHT-7 refining catalyst is the latest Mo-Co type catalyst of ultra deep hydrogenation for diesel desulfurization. When the number of active center and intrinsic activity is increased, the effective active center for removal of macromolecule sulfide improved also. Compared with last generation catalyst, the relative activity of AM-DHT-7 increasing more than 50%, keeping excellent ability of resistance to carbon poisoning and improving stability of catalyst activity.

Refining catalysts with high activity and stability are composed of three main components: the active component, the carrier and the additives. The active component is mainly the active metal, which can provide activity to the catalyst, specifically the VIB and V metal oxides or sulphides, such as tungsten, palladium, etc.; the carrier, which can affect the catalyst's active component dispersion, specific surface area, selectivity, stability, etc., is usually used in the hydrogenation refining catalyst process, such as Co, W. Mo. Ni and other active components, the carrier used is alumina In the preparation of diesel hydrotreating catalysts, acidic additives can be added to the catalyst to enhance the acidity of the catalyst and improve its denitrification ability, e.g. B, F. P are commonly used. In general, the active metals in current industrial diesel hydrotreating catalysts are mainly nickel, tungsten, cobalt and molybdenum in the form of sulphides, while the carriers are alumina or silica-alumina.

Physical properties

Applications

Improve the ability of effective active center for the removal of macromolecule sulfide.

The performance indicators for refining catalysts with high activity and stability, include three main aspects: activity, selectivity and stability. Catalyst activity refers to its ability to increase the reaction rate and is measured by ensuring that the feed and operating conditions are the same, based on the catalyst temperature required to produce a compliant product; catalyst selectivity refers to its favourability compared to other reactions and is measured in terms of product yield; catalyst stability refers to the migration of catalyst performance over time when operating conditions and feed are constant and is measured in terms of the rate of change. Catalyst stability is the change in catalyst performance over time when operating conditions and feed are constant, measured by the rate of change. When preparing catalysts for diesel hydrofinishing, their performance must be considered so that they meet the relevant requirements.
