摘要： Swelling clay minerals are made up of elementary three-layer platelets consisting of a central layer of octahedrally oxygen-surrounded metal ions (octohedron layer), which layer is surrounded by two tetrahedrally surrounded, silicon atom-containing layers (tetrahedron layers), a number of such elementary platelets being optionally stacked. The dimensions of the clay platelets vary from 0.01 νm to 1 νm, the number of the stacked elementary three-layer platelets varies from on average one platelet to twenty platelets, while in the octahedron layer at most 30 at.% of the metal ions has been replaced by ions of a lower valency and in the tetrahedron layers at most 15 at.% of the silicon ions has been replaced by ions of a lower valency, such a replacement having taken place in at least one of these layers and these layers having a deficiency of positive charge because of the replacement. They are prepared by bringing the pH of an aqueous liquid containing the components of the clay to a value of 3-9 and the temperature of the liquid to a value of from 60 to 350 °C and maintaining it at said value for the time required for the reaction, the pH being maintained at a value within said range.

摘要： The present invention is directed to a process for removing SO2 from an SO2-containing gas stream by catalytically reducing the SO2 to elemental sulphur, in which process a gas stream comprising SO2 and a reductor chosen from H2, CO, and a mixture thereof, the molar ratio of the reductor to the SO2 being between 0,1 and 10, is contacted, at a temperature in the range of 180° to 300 °C and a pressure of between 1 and 60 bar, with a sulphur resistant catalyst comprising at least one hydrogenation function. The catalyst preferably comprises a Group VIB metal component and/or a Group VIII metal component on a carrier. The process according to the invention can be used for removing SO2 from SO2-containing gas streams derived from various sources, int. al., from a modified SuperClaus unit. The process according to the invention permits the removal of SO2 from an SO2-containing gas stream in a simple manner with high SO2 conversion and a high selectivity for elemental sulphur.

摘要： The invention pertains to a catalyst at least comprising a hydrogenation metal component and a swelling synthetic clay consisting of elemental clay platelets, with the average diameter of the clay platelets not exceeding 1 micron and the average degree of stacking of the clay platelets not exceeding 20 platelets per stack. The catalyst is especially suitable for the hydroprocessing of hydrocarbon feeds, the term 'hydroprocessing' encompassing all processes in which a hydrocarbon feed is treated with hydrogen. The clays which are suitable for use in the catalyst according to the invention may be prepared as described in Netherlands patent application No. 9401433.
