| Any single energy and resource technology is hard to satisy the need of resource supply which is high efficiency,low pollution,low cost of our country in the future years.Based on synthetic gas,there will be a bright outlook on mutil-chemical products and power's polygeneration system,even intergration energy and resource using system have large intergrated scale and benefit.Advanced gasification system,methane gasification system,methanol of fluid phase methanol and fuel gas—vapor power technology are keys of internal polygeneration system.The paper mainly studies on synthesis gas which the ratio of H2/CO is between 1.0 and 2.0.Thus,we should look for a new low cost, low pollution,short flow technical route while producing synthetic ammonia.The thesis takes fine coal as main raw material first being composed of the forecast being in progress to exporting synthentic gas.Secretly scheme against for simplification since the at present coal gasifier technology is already pretty mature,the thesis adopts with the Shell gasification furnace part gasification index data announcing,make use of a stove to forecast the composition and H2/CO balancing a coal gas outlet going down a gasification furnace in certain the temperature,pressure and entrance condition coming inner chemical equilibrium principle and MATLAB language.Result is indicated:The coal gas composition effect gasification pressure is balanced face to face is not big;The steam bellyful may make effective gas(H2+ CO)contents come down;In syngas,H2/CO controls in 0.4.It can be seen that H2/CO insists to hang down, must increase CO shifting the adjustment coming to be in progress the handicraft.Take coke-oven gas as main raw material secondly,by the tool that MATLAB language and Fluent simulate a software,must catalyze a part oxidizing following the simulation research being in progress to the person.The mathematic model has rushing waters flow equation,radiation model,energy equation,is not that the in advance turbid combustion model carries out a simulation.Simulation result is indicated:Gasification pressure enhancing is harmful for methane in coke-oven gas to change;Improve the reactor inner changing the temperature,the conversion to coke-oven gas middle methane helps very much;Oxygen is the temperature deciding to gasify within the reactor and exports constitutive key factor of syngas comparing with the coke-oven gas.With the fact that oxygen increases by comparing with the coke-oven gas,the gasification balance temperature improves also with that; While both volume ratios are 0.1,effective syngas gas(H2 + CO)maximizing is 98.4%,CH4 in coke-oven gas changes nearly completely;The different oxygen and coke-oven gas compare,H2/CO is in 2.5～in generated syngas between 4.5. It can be seen that H2/CO is partial to height,the technology increasing the varying voltage adsorption be obliged to gets rid of a hydrogen or the handicraft increasing water gas alternation adds supplemental the adjustment coming to be in progress carbon.The optimization being in progress finally,to the process how output-related system to compose gas preparation in studies,coal and the coke-oven gas combine soon carrying out reaction within the reactor,to look forward to giving birth to a child out directly how output-related system H2/CO needed by lower reaches chemical products compares in.Calculation bear fruit is indicated:By changing feed condition,being able to get H2/CO = directly,1.0～adjustable between 2.0 composes a gas;Syngas middle effective gas component(H2 + CO)greater than above 90%;The basic simulating result and calculation bear fruit is consistent,the temperature distributes condition and the document is consistent,explain that fine coal unites with coke-oven gas gasifying is feasible.The conclusion reaches,thesis fine coal and coke-oven gas ally self with new handicraft of gasification to have the following characteristic:(1)by changing feed condition,not bad 1.0～adjustable syngas producing out H2/CO = directly between 2.0,effective gas component(H2 + CO)above 90%;(2)the province has got rid of a water gas shifting process,the varying voltage adsorption has got rid of the hydrogen technology or has filled up carbon working procedure;(3)adopt high temperature must catalyze oxide law,can make hazardous wastes in coke-oven gas all under the hot environment burning off or change,have decreased by contaminating to the environment,have omitted expensive catalysator sigmatism thereby.Therefore owing handicraft optimization having realized equipment in synthentic gas preparation stage, make entire system reach the saving energy and reducing consumption purpose. Be also one kind of clean productive technology of high-effect at the same time, should have very high research value.
