Abstract: A process for oligomerising alkenes having from 3 to 6 carbon atoms which comprises contacting a feedstock comprising a) one or several alkenes having x carbon atoms, and, b) optionally, one or several alkenes having y carbon atoms, x and y being different, with a catalyst containing a zeolite of the MFS structure type, under conditions to obtain selectively oligomeric product containing predominant amounts of certain oligomers. The process is carried out at a temperature comprised between 125 and 175° C. when the feedstock contains only alkenes with 3 carbon atoms and between 140 and 240° C., preferably between 140 and 200° C. when the feedstock contains comprises at least one alkene with 4 or more carbon atoms.

Abstract: Porous material (1) for catalytic conversion of exhaust gases including a carrier with a first porous structure (2, 2?), and an oxidation catalyst (OX) which in the presence of oxygen (O2), according to a first reaction (3), has the ability to catalyze oxidation of nitrogen monoxide (NO) into nitrogen dioxide (NO2) and, according to a second reaction (4, 4?), to catalyze oxidation of a reducing agent (HC), which oxidation catalyst (OX) is enclosed inside the first porous structure (2, 2?). The invention is characterized in that the oxidation catalyst (OX) includes iron (Fe) and silver (Ag) loaded on a zeolite. The invention also relates to a method and an arrangement and a catalytic conversion device that utilizes the porous material, and indicates an advantageous use of the porous material.
