Description
Technical field
The present invention relates to a kind of high activity loading type iron-based preparation of low carbon olefines by synthetic gas Preparation of catalysts method, relating in particular to a kind of is carrier with the modified silica-gel, the low cost that the interpolation metal promoter is modified and the high activity iron-based preparation of low carbon olefines by synthetic gas Preparation of catalysts method that is easy to commercial Application.
Background technology
Low-carbon alkene such as ethene, propylene is important basic Organic Chemicals, and along with the development of chemical industry, its demand is more and more big.Up to now, produce the approach of low-carbon alkenes such as ethene, propylene mainly by the light oil cracking process, along with the exhaustion day by day of petroleum resources in the global range, following energy resource structure certainly will shift.Compare with petroleum resources, coal is relative with natural gas resource abundant, and exploitation has great importance based on the low-carbon alkene production technology of coal and natural gas.Exploitation from synthesis gas (can be converted to by natural gas and coal) is directly produced ethene, propylene technology not only can reduce the dependence to petroleum resources, and some chemical industrial expansions in rich gas oil starvation area are had significance.
CN1065026A discloses a kind of preparation of ethylene by use of synthetic gas method, relating to the Preparation of catalysts method is chemical precipitation method, mechanical mixing, adopted noble metal or rare metal, kind of chemical element surplus niobium, gallium, praseodymium, scandium, indium, cerium, lanthanum, the ytterbium etc. ten for example, ethylene selectivity is 65%-94%, but the CO conversion ratio is very low, only about 10%, 12% and 15%, CO recycles the consumption that certainly will bring the energy, and catalyst cost height.
CN01144691.9 discloses nanocatalyst of a kind of preparation of ethylene by use of synthetic gas, propylene and preparation method thereof, adopts laser pyrolysis processes to prepare with Fe in conjunction with the combination technique of solid phase reaction
3C is that main Fe base nano-catalyst is used and preparing low-carbon olefin, and has obtained certain effect, but owing to need practical laser technology, makes preparation technology more loaded down with trivial details, and raw material adopts Fe (CO)
5, the cost of catalyst is than higher, the industrialization difficulty.
CN03109585.2 discloses a kind of iron/activated-carbon catalyst for the synthesis of gas ethene processed, propylene, butene reaction, adopt active carbon as carrier, Fe is as the activated centre, adopt vacuum impregnation technology successfully Fe to be loaded on the active carbon, make Fe and auxiliary agent be able to high degree of dispersion on active carbon, thereby the raising catalytic effect, and greatly reduce the cost of catalyst.And catalyst CO conversion ratio under the condition of no raw material circulation can reach 96-99%, and the CH compound selective reaches 69.5% in the gas-phase product, therein ethylene, propylene, butylene selectively reaching more than 68% in the CH compound.But active carbon influences service life and the stability of catalyst as catalyst carrier not only bad mechanical strength but also shaping of catalyst difficulty, is unfavorable for commercial Application.
Compare the active carbon silica supports and not only have acid resistance, hear resistance (can at 500～600 ℃ of following long reactions) and wearability, and silica is easy to moulding, specific area is bigger, and all have controllability, be more suitable for as catalyst carrier.Few silica that adopts mainly is because Fe and SiO as carrier in the reaction of alkene but directly prepare at the base supported synthesis gas of Fe at present
2Strong interaction between the carrier causes part Fe to be difficult to be reduced, and is difficult to reach comparatively ideal reactivity.
