Definitions
- Tetrahalosilane is an important starting material for the production of silicon. In this regard, reference is made to the extensive state of the art.
- the present invention has for its object to provide a process for the production of tetrahalosilanes, which is characterized by a particularly high efficiency.
- Halogenwasserstoffström be heated and the resulting SiX 4 is collected or distilled off.
- Residues still contain carbon in the form of high-viscosity hydrocarbons. This carbon is used to reduce the present in the rock masses Si0 2
- Reducing agent used and this is used specifically for the production of tetrahalosilanes, which can then be converted in further reaction steps to the desired Si. It is essential that the starting materials in question (rock masses, residue masses) contain enough carbon to provide the desired
- the masses contain, for example, highly viscous Hydrocarbons in the form of bitumen or tar.
- the C content of the masses is preferably determined. If this is insufficient, carbon is added to the masses before or during heating. In this case, preferably cheaper carbon (hard coal, dried biomass, coal, etc.) is used.
- the masses for residual water removal are heated to about 400-500 ° C. and then to about 1000-1300 ° C. for obtaining S1X 4 .
- rock masses are, for example, oil sands or oil shale.
- oil sands or oil shale.
- rock mass should also cover oil sludge, although this is not a rock. For example, these rock masses become low-viscosity
- inventive method can be used.
- the determination of the C content if appropriate the addition of carbon and the heating in two stages (400-500 ° C. for residual water removal, 1000 ⁇
- Electromagnetic alternating fields for example, microwave
- the method is achieved by a process for the production of tetrahalosilanes (SiX)
- existing carbon is used as a suitable energy source for the further processing of the SiX obtained to Si, so that also in this process variant, an effective or efficient use of existing materials in the starting materials.
- SiF 4 is obtained in situ in this process.
- SiX 4 obtained to Si in a known manner.
- SiX 4 can be converted plasma-chemically into polyhalosilanes. Thermolysis at about 800-1000 ° C then gives Si and SiX 4 which can then be recycled.
- the residue contains alkali-alkaline earth oxides and / or
- prepared rock masses or residue masses are preferably contained by removal of the rock contained in the rock
- Extraction method such as SAGD (steam assisted gravity
- Hydrocarbons have been removed. This may be, for example, rock masses which have a relatively low proportion of low-viscosity hydrocarbons, so that their recovery is not worthwhile, or in which the low-viscosity hydrocarbons contained have been converted into higher-viscosity hydrocarbons
- thermolysis pyrolysis (T from RT to about 800 ° C), which significantly increases the C content.
- Hydrocarbons (petroleum) supplied to an external use or can also be used as an energy source for heating the masses.
- the C content in the masses can be controlled (enriched).
- the C content in the masses can be controlled (enriched).
- as much oil as possible is recovered from the masses, so that only the
- SiF 4 was characterized by 1 H and 19 F NMR and GC / MS analysis.
