Fischer-tropsch synthesis wax residue processing method and processing system

Abstract

The invention discloses a fischer-tropsch synthesis wax residue processing method and processing system. The method comprises the following steps of 1, performing heating treatment on wax residue, wherein wax of the wax residue remains in a melting state; 2, using a filter press to conduct filtering separation on the liquid wax residue after the heating treatment, wherein the filtering separation temperature is 160 DEG C so as to obtain molten wax and solid residue; and 3, carrying out water decomposition treatment on the obtained solid residue again, wherein the water decomposition temperature is 160 DEG C so as to obtain molten wax and solid waste residue. The fischer-tropsch synthesis wax residue processing method is capable of carrying out full recovering of the wax in the wax residue, thus avoiding the resource waste and greatly improving the economic benefit.

Description

technical field [0001] The invention relates to a wax residue treatment method and system, in particular to a Fischer-Tropsch synthesis wax residue treatment method and a treatment system. Background technique [0002] Fischer-Tropsch synthesis usually uses synthesis gas as a raw material to synthesize paraffin-based liquid fuels under catalysts and appropriate reaction conditions. After Fischer-Tropsch synthesis, the catalyst is usually discharged from the Fischer-Tropsch synthesis unit in the form of wax residue. Since the wax residue contains 20-75wt% wax, when the wax residue is treated as a solid waste, the wax in the wax residue is usually converted into carbon dioxide and water by incineration, and the remaining waste residue is treated as a general solid waste. [0003] Although the above-mentioned treatment method solves the problem of environmental protection discharge of wax residues, the wax in the wax residues is directly incinerated, resulting in a great waste...
