Definitions
- the present invention is in the field of catalysts and catalysts for producing a mixture of hydrogen rich gases and carbon monoxide, known in the art as "synthesis gas". Particularly, the invention relates to a catalyst for producing "synthesis gas” from a hydrocarbon mixture and process for obtaining said catalyst.
- synthesis gas hydrogen rich and carbon monoxide gases
- synthesis gas is widely used in the petrochemical industry to produce synthetic fuels, methanol, ammonia, urea, among others.
- synthesis gas is produced from a process known in the art as hydrocarbon steam reforming, and is then converted into synthetic fuel by means of a “Fischer-Tropsch” synthesis.
- the production stage of the "synthesis gas” is subdivided into two sections: pre-reforming the raw material and recycling stream from the "Fischer-Tropsch” synthesis and steam reforming of hydrocarbons.
- the main reactions that occur in the steam reforming process are as follows:
- the steam reforming process may have different configurations depending on the type of raw material and the destination of the "synthesis gas" to be produced.
- synthetic consists of including in the process a pre-reforming reactor of the raw material.
- Said pre-reforming step is normally carried out in a fixed bed reactor containing a nickel-based catalyst in a temperature range of 350 ° C to 550 ° C, a vapor / carbon ratio in the range 1 and 5, and pressures up to 40 bar.
- nickel-based pre-reforming catalysts are subject to coke (Carbon) deactivation on their surface. Such a phenomenon results in reduced catalyst activity or increased pressure drop in the reactor or both.
- the use of naphtha as a raw material is known to generate greater coke deposition in a pre-reform catalyst than the use of natural gas, for example.
- the use of olefin-containing raw materials is one of the most important factors in coke formation in said catalysts.
- US 3,481,722 teaches a liquid hydrocarbon steam reforming process comprising first-stage processing of a hydrocarbon, water vapor and hydrogen stream onto a platinum group metal-containing catalyst at temperatures below 700 ° C.
- said solution has high costs arising from the replacement of nickel with a noble metal, which limits the use of the catalyst on a large scale.
- PI 1000656-7 protects a nickel-based steam reforming process and catalyst with the incorporation of alkali metals. If, on the one hand, the addition of alkali metals reduces coke deposition in said catalyst, on the other hand, it is known that in nickel-based steam reforming catalysts said alkali metals reduce catalyst activity. To work around the problem, a specific method of catalyst preparation is taught.
- US 7,365,102 discloses a pre-reform process for obtaining methane-enriched hydrocarbon charge stream employing a molecular oxygen free oxidant gas (water) stream.
- the mixture is heated to a range of values of 500 ° C to 700 ° C in the presence of a catalyst Ni-based, controlling the ratio H 2 0 / hydrocarbon in bridging less than one reactor so that the conversion of hydrocarbons with a molecular weight greater than methane does not exceed the range of 30% - 40%.
- US 7,427,388 discloses a process for natural gas preforming which includes contacting steam, hydrogen and said natural gas with a nickel and oxygen based catalyst in less than is required to partially oxidize hydrocarbons. THE Adding oxygen to the pre-reform process entails additional production costs due to the purification of atmospheric air when used as a source of oxygen. In addition, process limitations due to temperature increase due to oxygen use may occur.
- the present invention advantageously provides economic gains by not replacing nickel with noble or alkaline metals and by not introducing oxygen to the process, which minimizes production costs.
- the present invention aims to enable a catalyst for the production of synthesis gas and its obtaining process which, besides having a higher resistance to coke deposition on the catalyst surface, does not introduce limitations to the process variables, maintain levels of activity throughout the steam reform process and which has a lower production cost.
- the catalyst for the preform process is formed by an inorganic oxide support, a mixture of nickel, lanthanum and cerium and a promoter element.
- Figure 1 shows a Temperature (° C) versus Mass Change (% m / m) plot, which represents the carbon deposition rate on pre-reforming catalysts known in the art.
- Figure 2 shows a Temperature (° C) versus Mass Change (% m / m) plot comparing the carbon deposition rate on various commercial nickel-based pre-reforming catalysts with catalysts prepared according to present invention.
- Figure 3 shows a Temperature (° C) versus Mass Change (% m / m) graph comparing the carbon deposition rate on a specific commercial nickel pre-reforming catalyst with catalysts obtained according to the present invention.

- the catalysts were tested comparatively on a thermogravimetric analysis equipment (TGA Mettler Toledo TGA / SDTA851 E). The tests were performed using 25 mg of ground catalyst to obtain particles smaller than 0.088 mm (170 mesh). Initially a pretreatment step was performed by passing 40 mL / min. of a mixture containing 10% (v / v) Hydrogen in Argon saturated in water vapor at 15 ° C together with 40 mL / min.
