Embodiment Construction

[0017]The reactor is suitable for carrying out an exothermic process, such as a Fischer-Tropsch process. The reactor comprises a reactor shell, inlets for introducing reactants and coolant into the reactor shell, outlets for removing product and coolant from the reactor shell.

[0018]A reactor according to the present invention is a slurry reactor. The cooling modules in the reactor according to the present invention are suitable for use in a slurry reactor. The cooling tubes of the cooling modules are normally placed within the volume in which the reaction takes place and heat is transferred from the liquid continuous matrix to the tube walls.

[0019]The catalyst in the reaction volume may be a particulate catalyst. Additionally or alternatively, the catalyst in the reaction volume may be a structured catalyst, for example a shaped porous structure. A structured catalyst may form an ebullated bed. A structured catalyst may be fixed in the reaction volume. When the catalyst is fixed in ...

Abstract

The invention relates to a reactor for carrying out an exothermic process comprising a reactor shell, inlets for introducing reactants and coolant into the reactor shell, outlets for removing product and coolant from the reactor shell, and a plurality of cooling modules, the reactor comprising for at least some of the modules a skirt for guiding gas underneath the modules.

Description

[0001]This application claims the benefit of European Application No. 09159295.6 filed May 4, 2009, which is incorporated herein by reference.BACKGROUND[0002]The present invention relates to a reactor for carrying out an exothermic process, such as a Fischer-Tropsch process, comprising cooling modules. The reactor is compartmentalized. The invention further relates to the use of such a reactor for carrying out an exothermic process.[0003]As is explained in WO 2005 / 075065, Fischer-Tropsch processes are often used for the conversion of gaseous hydrocarbon feedstocks into liquid and / or solid hydrocarbons. The feedstock, e.g. natural gas, associated gas, coal-bed methane, residual (crude) oil fractions, coal and / or biomass is converted in a first step to a mixture of hydrogen and carbon monoxide, also known as synthesis gas or syngas. The synthesis gas is then converted in a second step over a suitable catalyst at elevated temperature and pressure into paraffinic compounds ranging from ...
