| titleOfInvention | A kind of method and system utilizing fine coal preparing ethylene |
| abstract | The invention belongs to coal chemical technology, a kind of method utilizing fine coal preparing ethylene is proposed, including step: 1) pyrolysis upgrading, 2) pressure-variable adsorption carries hydrogen, and 3) smelting production carbide, 4) CO conversion decarburization hydrogen manufacturing, 5) acetylene occurs, 6) acetylene hydrogenation reaction, 7) cryogenic separation, it is thus achieved that ethylene and other hydrocarbon productss.The present invention uses cheap middle low order powdery raw coal, the high-quality resources such as the high block coke of fictitious hosts, semi-coke, anthracite are as the raw material producing carbide, process energy consumption is low, obtains tar and the pyrolysis gas by-product of high added value in pyrolytic process, improves technique macroeconomic；Pyrolysis solid product after pyrolysis uses heat to send technique, makes full use of its sensible heat, reduces furnace of calcium carbide power consumption；The hydrogen obtained after utilizing the hydrogen and calcium carbide stove exhaust conversion that pyrolysis gas product pressure-variable adsorption obtains reacts for acetylene hydrogenation, another product of furnace of calcium carbide and CO 2 Reaction generates nano-calcium carbonate, decreases environmental pollution. |
