A die is provided for extruding elongate particles suitable for use in catalysis. The die comprises a plurality of channels extending from an inlet to an outlet. From the inlet to the outlet each channel comprises a first section with a helical bore with a non-circular cross-section, and a second section with a cylindrical bore. The cylindrical bore of the second section which has a diameter equal or greater than that of the first section. The second section is at least twice as long as a diameter of the first section.

Particle extrusion

A process for performing a Fischer Tropsch reaction comprising (a) providing syngas to a reactor, said reactor comprising catalyst particles that have been produced by extruding a paste using a die comprising a plurality of channels extending from an inlet to an outlet, wherein from the inlet to the outlet each channel comprises a first section with a helical bore with a non-circular cross-section, and a second section with a cylindrical bore which has a diameter equal or greater than that of the first section, wherein the second section is at least twice as long as a diameter of the first section; (b) providing the following process conditions in the reactor: a temperature from 125 to 350&#xb0; C., and a pressure from 5 to 150 bar absolute, and a gaseous hourly space velocity from 500 to 10000 Nl/l/h; and (c) removing Fischer Tropsch product from the reactor.
