摘要:
The invention pertains to a lean process for the production of hydrocarbons in which a tail gas is subjected to shift conversion, carbon dioxide removal, and then to purification in a PSA to obtain a hydrogen stream comprising more than 99 vol % hydrogen. The Fischer Tropsch process is a single-stage process. The hydrogen stream can be used to upgrade the Fischer-Tropsch hydrocarbons.

The invention relates to a process for the catalytic partial oxidation of a hydrocarbonaceous feedstock, wherein a feed mixture having the hydrocarbonaceous feedstock and a molecular-oxygen containing gas is contacted with a catalyst system having an upstream part and a downstream part, the downstream part being in the form of a porous catalyst bed, wherein the catalyst system is retained in a reactor, the reactor having an upstream part that contains the upstream part of the catalyst system and a downstream part that contains the downstream part of the catalyst system, wherein the upstream part of the catalyst system only partly fills the cross-sectional area of the fluid flow path of the upstream part of the reactor and the downstream part of the catalyst system completely fills the cross-sectional area of the fluid flow path of the downstream part of the reactor. The invention further relates to a reactor having such a catalyst system and a catalytic reaction zone for the water-gas shift conversion of the effluent of the catalyst system, to a fuel cell system having such a reactor and a fuel cell, and to a vehicle provided with such a fuel cell system.
摘要:
The present invention relates to the use of wax for food applications, which wax has a congealing point of more than 65.degree. C. and a Saybolt color of more than +25, which wax is obtainable by subjecting a wax prepared in a Fischer-Tropsch synthesis process to a hydrogenation treatment to prepare a hydrogenated wax containing less than 1.5% by weight of oxygenates, fractionating the hydrogenated wax to obtain a hydrogenated wax fraction having a desired congealing point, and subjecting the hydrogenated wax fraction to a hydrofinishing treatment. The present invention further relates a process for the preparation of a wax which comprises subjecting a wax prepared in a Fischer-Tropsch synthesis process to a hydrogenation treatment to prepare a hydrogenated wax containing less than 1.5% by weight of oxygenates, fractionating the hydrogenated wax to obtain a hydrogenated wax fraction having a desired congealing point, and subjecting the hydrogenated wax fraction to a hydrofinishing treatment. Moreover, the present invention relates to a wax suitable for use in food applications.
