| titleOfInvention | Fischer-tropsch synthesis catalyst, method for preparation and use thereof |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to Fischer-Tropsch synthesis catalysts. Described is a micro-spherical iron-containing catalyst for Fischer-Tropsch synthesis in a high temperature suspended bed reactor, the catalyst containing an Fe element as a basic component, characterised by that the catalyst also contains a K promoter, a transition metal promoter M and a modified structure promoter S, wherein the transition metal promoter M is any combination of two or more types of metals selected from Cr, Cu, Mn and Zn; the structure promoter S is in form of SiO 2 and/or Al 2 O 3 , wherein both SiO 2 and Al 2 O 3 are modified by MoO 3 , TiO 2 and/or ZrO 2 ; and the weight ratio of each component Fe:M:K:S=100: 1-100:1-12:1-80, where the metal components are calculated based on metal elements, and the structure promoter is calculated based on oxides. Described is a method of preparing said iron-containing catalyst, which comprises the following steps: (1) preparing a solution of metal nitrates by using metal Fe, a transition metal M and nitric acid as raw materials, or directly dissolving the metal nitrates to prepare a mixed solution of the metal nitrates; wherein the transition metal M is one or more types of metals selected Cr, Cu, Mn and Zn; (2) adding a solution or suspension of a structure promoter S into the solution of the metal nitrates prepared at step (1) and thoroughly mixing to obtain a mixed solution; (3) adding ammonia water as a precipitant into the mixed solution at step (2), or adding the mixed solution at step (2) into the precipitant in form of ammonia water, or co-precipitating the mixed solution from step (2) with the precipitant in form of ammonia water by merging to prepare a precipitated suspension; (4) filtering the precipitated suspension to obtain a filter cake of catalyst; (5) adding distilled water and a precursor of a K promoter into the filter cake to achieve the desired catalyst composition, and pulping to obtain a catalyst suspension; and (6) obtaining from the catalyst suspension prepared at step (5) particles with a micro-spherical shape by spray-drying and then roasting to obtain a micro-spherical iron-containing catalyst; wherein, the addition of the structure promoter in step (2) can instead be carried out at step (5) after addition of the precursor of the K promoter, or respectively adding one part of the structure promoter at steps (2) and the other at step (5). Described is a Fischer-Tropsch synthesis method, wherein the Fischer-Tropsch synthesis reaction takes place in a suspended bed reactor at high temperature of 250-300°C in order to convert synthesis gas into liquid hydrocarbons in the presence of the catalyst described above. n EFFECT: high selectivity of the catalyst. n 14 cl, 2 tbl; 8 ex |
