Embodiment 1

[0090] First, the influence of the mixing ratio of the catalyst for the reverse water gas shift reaction (RWGS) and the catalyst for the Fischer-Tropsch synthesis reaction (FTS) will be observed. In the catalyst layer of 0.4g mass in total, weigh 0.3g as FTS catalyst and contain the mixed catalyst of 100 parts by weight of Fe, 13 parts by weight of Cu, 12 parts by weight of Al, K15 parts by weight (marked as 100Fe-13Cu- 12Al-15K), then weigh out 0.1g in Ce 2 The RWGS catalyst loaded with 1 wt% Pt in the O support (hereinafter denoted as 1Pt-Ce 2 O), and uniformly mix the two catalysts. Mix the above two types of catalysts evenly into 2 g of diluent (α-alumina) and follow as follows figure 2 The manner shown was filled into a 1 / 2 inch stainless steel fixed bed reactor (carbon monoxide generation section). Before starting the reaction, the catalyst filled into the reactor was heated at 400°C with 2000mlh -1 gcat -1 The flow rate of hydrogen was used for 2 hours of reductio...

Embodiment 2

[0092] In a total mass of 0.4g of the catalyst layer, 0.2g of FTS catalyst with a composition ratio of 100Fe-13Cu-12Al-15K and 0.2g of a composition ratio of 1Pt-Ce 2 O's RWGS catalyst was mixed. The carbon dioxide conversion reaction was carried out under the same remaining conditions as in Example 1 above, and the results are shown in Table 1.

Embodiment 3

[0094] 0.1 g of an FTS catalyst having a composition ratio of 100Fe-13Cu-12Al-15K and 0.3 g of a RWGS catalyst having a composition ratio of 1Pt-Ce2O were mixed in a total mass of 0.4 g of the catalyst layer. The carbon dioxide conversion reaction was carried out under the same remaining conditions as in Example 1 above, and the results are shown in Table 1.

Abstract

The present invention relates to a system and a method for carbon dioxide conversion, the system comprising: a carbon monoxide generation part for generating carbon monoxide through a reverse water gas shift reaction; and a hydrocarbon generation part for generating hydrocarbons through a Fischer-Tropsch reaction, wherein the carbon monoxide generation part is filled with a catalyst for a reversewater gas shift reaction together with a catalyst for a Fischer-Tropsch reaction, so as to further improve the CO yield of the carbon monoxide generation part even at a low temperature over that of when only the catalyst for a reverse water gas shift reaction is used, thereby ultimately improving the hydrocarbon yield of the hydrocarbon generation part, and the energy of a Fischer-Tropsch exothermic reaction is reserved as the energy required for the endothermic reaction of a reverse water gas shift such that energy efficiency and process yield improve, and thus operation and maintenance costscan be reduced.

Description

technical field [0001] The present invention relates to a system and method for converting carbon dioxide into more useful compounds, and more particularly to a method that can effectively save energy and System and method for obtaining product with high yield. Background technique [0002] Coal and petroleum are fossil energy sources that account for more than 50% of all energy. They have been used as an important source of energy for humans in the past few centuries, and humans do not use thermodynamically stable nitrogen dioxide in various energy conversion projects. Instead of a separate post-treatment process, it is discharged directly. [0003] However, recently, as people realized that nitrogen dioxide is the main greenhouse gas that accounts for 55% of the various factors that cause global warming, a variety of technologies for the removal of carbon dioxide have been proposed, of which the most concerned It is a technology that uses catalysts to convert carbon diox...
