Abstract
The present invention relates to a kind of preparation method for synthesizing gas by reforming methane with co 2 catalyst, the catalyst includes active component, auxiliary agent and carrier;The preparation method of the catalyst comprises the following steps:Catalyst precarsor A is prepared first, then reduction treatment is carried out to catalyst precarsor A, it is well mixed auxiliary agent presoma is soluble in water with furfural aqueous solution, then it is added to together with catalyst precarsor A in autoclave, reacted after adding solution C, filtering gained solid sample obtains catalyst again after drying, calcination process after obtained solidliquid mixture processing separation.This method takes full advantage of waste residue oil hydrogenating treatment catalyst, has saved cost, and the catalyst reaction activity of preparation is high, both reduces metal consumption, the selectivity of product is improved again.
Description
Technical field
The present invention relates to a kind of preparation method for synthesizing gas by reforming methane with co 2 catalyst, more particularly, to a kind of preparation method for synthesizing gas by reforming methane with co 2 loading type nickel-based catalyst.
Background technology
Methane and carbon dioxide is cheap in nature and resourceful carbon compound; using the reforming reaction producing synthesis gas of methane and carbon dioxide, for alleviating energy crisis, mitigate due to caused by the discharge of greenhouse gases global climate warm it is significant.The synthesis gas that methane is prepared with CO 2 reformation has H2The characteristics of/CO≤1, go for F- T synthesis, the high chemicals of added value such as production higher hydrocarbon.
The catalyst for being presently used for synthesizing gas by reforming methane with co 2 is more based on metal supported catalyst, is broadly divided into two major classes:Noble metal and non-precious metal catalyst.Although noble metal catalyst is with excellent reactivity worth, expensive, sintering is also easy under hot conditions and is lost in.Non-precious metal catalyst is that nickel or cobalt are carried on the carriers such as aluminum oxide, silica, magnesia, zirconium oxide, titanium oxide, the advantage of this system is that reactivity worth is good, catalyst preparation low cost, but catalyst carbon accumulation resisting ability is low, can cause inactivation because of carbon distribution, sintering.
