A continuous process for preparing exo-THDCPD by isomerization of endo-THDCPD includes the step of passing endo-THDCPD and hydrogen gas successively through a first reaction zone filled with a hydrogenation protectant and a second reaction zone filled with an isomerization catalyst to perform a hydroisomerization reaction so as to obtain exo-THDCPD, wherein the hydrogenation protectant is a supported metal hydrogenation catalyst, and the isomerization catalyst is a metal-modified molecular sieve catalyst. The process converts endo-THDCPD to exo-THDCPD, with a conversion of greater than 86% and a target product selectivity of greater than 94%.

The present invention relates to a process for producing LPG from a hydrocarbon feed comprising polyaromatics, the process comprising contacting said feed in the presence of hydrogen with a M/A/zeolite catalyst under hydrocracking process conditions.

The invention relates to a coating suspension containing at least one platinum group metal on a support material, as well as manganese(II) carbonate, and to a method for coating a catalyst support substrate.

A cluster-supporting catalyst including porous carrier particles having acid sites, and catalyst metal clusters supported within the pores of the porous carrier particles. The catalyst metal clusters are obtained by supporting catalyst metal clusters having a positive charge, which is formed in a dispersion liquid containing a dispersion medium and the porous carrier particles dispersed in the dispersion medium, on the acid sites within the pores of the porous carrier particles through an electrostatic interaction.

A method to remove silica from a silica containing material characterized in that it comprises (i) contacting said silica containing material with a first metal ion carbonate, to obtain a first composition, and (ii) heating said first composition in a vessel at a temperature sufficient to increase the pressure above the atmospheric pressure in said vessel or at a pressure of at least 2 bara and at a temperature of at least 80 C., preferably 100 C. wherein said pressure is preferably autogeneously generated, wherein the total amount of water of said first composition originating from (a) the silica containing material and from (b) the first metal ion carbonate is greater or equal to 4 mol of water per mol of metal ion carbonate, and wherein the first composition obtained at step (i) is not a suspension in water and is under solid state at standard temperature and pressure (STP), before the performance of step (ii) and wherein said silica containing material is a zeolite

A process for converting paraffins, especially light paraffins, e.g. C.sub.3-C.sub.8 paraffins, to higher boiling range paraffinic liquid hydrocarbons comprises endothermically dehydrogenating the light paraffin combined with a thermally coupled, exothermic reaction such as olefin oligomerization to supply heat for the endothermic conversion.

Provided is a method of encapsulating a metal in a zeolite. The method comprises inserting a metal precursor into a parent zeolite, and then converting the parent zeolite to a zeolite having a higher framework density than the parent zeolite. The conversion is achieved without the need of an organic structure directing agent.
