Description
Technical field:
The utility model relates to a kind of chemosynthesis reaction device, is specially a kind of synthesis reactor of dimethyl ether system gasoline.
Background technology:
Along with World Economics is fast-developing, petroleum resource consumption quickens, and the energy is shortage day by day.And coal reserves is considerably beyond oil and natural gas; Therefore; Greatly develop Coal Chemical Industry science and technology both at home and abroad, coal-based oil-producing technique obtains extensive concern, and wherein the preparing gasoline by methanol technology of differential responses device type such as the fixed bed successively developed of U.S. Mobil company, fluid bed is noticeable especially.
Methanol conversion is that hydro carbons system gasoline is a very complicated reaction system, and along with the growth in reaction time, methyl alcohol at first is converted into dimethyl ether, passes through condensation and reformation then, forms aliphatic hydrocarbon and aromatic hydrocarbon.The conversion reaction of three steps of methyl alcohol all is exothermic reaction, and the reaction heat ratio is roughly 1: 2: 2, and is as follows:
Methanol conversion is that gasoline is strong exothermal reaction, and reaction heat is 1674KJ/Kg in the time of 371 ℃, and in adiabatic condition, the temperature of reaction heat can be elevated to 590 ℃, and having substantially exceeded Methanol Decomposition is CO and H
2Temperature, beds is Yin Gaowen and make catalysqt deactivation very easily, so reaction heat must effectively shift out.
Summary of the invention:
The utility model prolongs catalyst life in order in the technique for preparing gasoline by methanol scheme, accurately to control reaction temperature, guarantees that reaction improves the gasoline earning rate smoothly and a kind of dimethyl ether system gasoline synthesis reactor is provided.
The utility model is realized by following technical scheme.A kind of dimethyl ether system gasoline synthetic reaction comprises having upper inlet and the tank body that exports down, in tank body, is provided with at least two modified ZSM-5s 5 type beds.The cooler that connects tank body is set between beds.Cooler is multidirectional two-tube annular refrigerating gas distributor.
In the production course of reaction, unstripped gas and circulating air are formed the upper inlet that gaseous mixture gets into the described synthesis reactor of the utility model, pass the modified ZSM-5 catalyst bed then from top to bottom successively.Blender contacts with catalyst when passing beds synthetic reaction takes place; Produce a large amount of heats simultaneously; Again with refrigerating gas; Send in the synthetic reaction through cooler like normal temperature circulating air, thus refrigerating gas can utilize reaction heat participate in reaction or diluting reaction heat is taken away, thereby the entire reaction course safety and stability is carried out.
Compared with prior art, the said dimethyl ether system gasoline of the utility model synthesis reactor can accurately effectively be controlled reaction temperature, prolongs catalyst life, and the gasoline earning rate is significantly improved.Simultaneously, energy-saving and cost-reducing, reduce investment.
