Embodiment 1 to 4 and comparative example 1 and 2

[0082] In the selective hydrogenation of acetylene in the presence of excess ethylene, ordered Co-Al-IMCs and Fe-Al-IMCs (Fe in Example 1 4 Al 13 ; o-Co in Example 2 4 Al 13; FeAl in Example 3 and CoAl in Example 4) the activity, selectivity and long-term stability were determined under the conditions described in the previous section, and compared with Pd / Al 2 o 3 (Comparative Example 1) and Pd 20 Ag 80 The catalytic performance of the alloy (Comparative Example 2) was compared.

[0083] Isothermal catalytic experiments were performed by heating the ordered intermetallic compound and the reference material in the amounts indicated in Table 1 (see column indicated for catalyst amounts) in helium to a reaction temperature of 473 K, followed by switching to ethylene-rich feedstock.

[0084] Using Fe 4 Al 13 The acetylene conversion of the powder and the corresponding selectivity as figure 1 shown, using o-Co 4 Al 13 The corresponding data for powders are plotted in ...

Abstract

The present invention relates to a process for the hydrogenation, in particular the selective hydrogenation of unsaturated hydrocarbon compounds, such as the selective hydrogenation of acetylene to ethylene, using a hydrogenation catalyst comprising an ordered intermetallic compound, namely an ordered cobalt- aluminum or iron- aluminum intermetallic compound. According to another aspect, the present invention relates to a catalyst comprising a support and at least one specific ordered cobalt -aluminum and / or iron-aluminum intermetallic compound supported thereon, as well as to the use of specific ordered intermetallic cobalt-aluminum and iron -aluminum intermetallic compounds as catalysts. The ordered cobalt-aluminum and iron-aluminum intermetallic compounds proved to be highly selective and long-term stable catalysts, e.g. in the selective hydrogenation of acetylene to ethylene in a large excess of ethylene.

Description

technical field [0001] The present invention relates to a hydrogenation method, in particular to the selective hydrogenation of unsaturated hydrocarbon compounds using hydrogenation catalysts containing ordered intermetallic compounds (i.e. ordered cobalt-aluminum or iron-aluminum intermetallic compounds). A catalyst comprising a carrier and at least one specific ordered cobalt-aluminum and / or iron-aluminum intermetallic compound, and the use of the specific ordered cobalt-aluminum and iron-aluminum intermetallic compound as a catalyst. Background technique [0002] The selective hydrogenation of unsaturated hydrocarbon compounds is of high industrial importance. Naphtha pyrolysis for the production of ethylene, propylene, butane, 1,3-butadiene and aromatics is a key process in the modern petroleum industry. To get from C 2 、C 3 and C 4 Alkynic compounds are almost completely removed from the fractions, typically using selective hydrogenation. [0003] For example, the ...
