Definitions
- the invention relates to a process for the removal of sulfur-containing compounds from a hydrocarbon-containing gas mixture with an adsorbent material, in which the degree of loading of the adsorbent material can be determined by optical testing.
- Natural gas refers to a variety of possible gas compositions, which may vary widely depending on the deposit: Natural gas may consist almost exclusively of methane (CH 4 ) but may also contain significant amounts of higher hydrocarbons. Higher hydrocarbons "are understood to mean all hydrocarbons from ethane (C 2 H 6 ), regardless of whether they are linear saturated or unsaturated, cyclic or aromatic hydrocarbons. Typically, the proportions of higher hydrocarbons in the higher molecular weight and higher vapor pressure natural gas decrease.
- Sulfur compounds of natural origin which can occur in low concentrations, should be mentioned in this context. Examples include hydrogen sulfide (H 2 S), carbon oxide sulfide (COS), carbon disulfide (CS 2 ) and light organo-sulfur compounds such as MeSH.
- H 2 S hydrogen sulfide
- COS carbon oxide sulfide
- CS 2 carbon disulfide
- MeSH light organo-sulfur compounds
- MeSH light organo-sulfur compounds
- the natural gas For safety reasons further sulfur compounds, so-called odorants, admixed. Natural gas is normally odorless and non-toxic, but it can lead to flammable mixtures in combination with air. In order to immediately detect an uncontrolled escape of natural gas, natural gas is mixed with intense smelling substances in low concentration, which cause the smell characteristic of natural gas.
- the sulfur-containing compounds in natural gas or LPG can lead to a strong and irreversible poisoning of the catalysts in a fuel cell or in a reformer. For this reason, the hydrocarbon-containing gases which are supplied to the fuel cell must be cleaned of all sulfur-containing compounds. For this reason, fuel cell systems always contain a desulphurisation unit for the natural gas or LPG used.
- Adsorptive processes are characterized by a simple process control.
- the hydrocarbon-containing gas stream is simply passed through an adsorber, which is usually in the form of a fixed bed.
- the sulfur-containing compounds are retained due to their chemical-physical properties. With the duration of operation, a continuous loading of the adsorber, so that ultimately exhausted after absorbing the absorption capacity no sulfur-containing compounds can be adsorbed. When exhaustion of the absorption capacity then it comes to the breakthrough of sulfur compounds.
- adsorbent material is defined in the present invention as a material that can reversibly or irreversibly bind or incorporate sulfur-containing compounds into other compounds. Many materials have been investigated to produce adsorbent materials with higher absorption capacity for sulfur-containing compounds. The following proved to be suitable:
- WO 201 1/033280 A1 discloses the use of ZnO for desulfurization.
- WO 201 1/031883 A2 and Hwahak Konghak (2010), 48, 4, 534-539 disclose the use of zeolites for desulfurization.
- Hwan et al. (APPLIED CATALYSIS B-ENVIRONMENTAL, 100, 7-2, p246-270), Lee et al. (JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY, 10, 1, p203-210) and Chul et al. (APPLIED CATALYSIS A-GENERAL, 334, 1-2, p129-139) describe the use of zeolites and doped zeolites for desulfurization.
- the sulfur breakthrough is often prevented by the exiting from the adsorber hydrocarbonaceous gas mixture by analytical methods, such as gas chromatography, infrared spectroscopy, XRD analysis, etc., is examined at certain time intervals for its sulfur content. If the sulfur content exceeds a specified threshold value, the replacement or regeneration of the adsorber material takes place.
- a disadvantage of the adsorptive process for the desulfurization of hydrocarbon-containing gas mixtures described in the prior art is that the degree of loading of the adsorber can not be easily and directly determined on sulfur-containing compounds and high absorption of the absorption capacity, without risking a sulfur breakthrough, only by special analytical Effort is possible.
