Abstract
The utility model relates to a chemical synthesis reactor, in particular to a methanol-to-gasoline reactor. The utility model solves the problem of temperature controlling in the technical proposal for producing gasoline by using methanol. The utility model comprises a tank body with an upper inlet opening and a lower outlet opening, at least two catalytic bed layers are arranged in the tank body, and a cooler interpenetrated through the tank body is arranged between the catalytic bed layers. The cooler is of an annular porous cold shocking gas distributor. The methanol-to-gasoline reactor of the utility model enables the methanol steam to directly react in the interior of the methanol-to-gasoline reactor to generate gasoline, LGP, and fuel gas, and can ensure that the temperature of the catalytic bed layers to be easily controlled within the required temperature range.
Description
Technical field
The utility model relates to a kind of chemosynthesis reaction device, is specially a kind of preparing gasoline by methanol reactor.
Background technology
Preparing gasoline by methanol is strong exothermic process, and its thermal discharge is about 1400KJ/KG, can represent with following three reaction formula:
CH
3OH---CH
3OCH
3+H
2O+10.08KJ (1)
CH
3OCH

Wherein one section invert point is about 270 ℃-360 ℃, and pressure is 2.3-2.4MPA, and two sections invert points are 300 ℃--and 400 ℃, pressure is 2.3-2.1MPA.Because this reaction is strong exothermal reaction, instantaneous temperature can reach 600 ℃ in the reaction, and beds very easily produces high temperature and makes catalyst deactivation, and to substantially exceed methanolysis be CO and H
2Temperature.
Summary of the invention
The utility model provides a kind of preparing gasoline by methanol reactor in order to solve temperature controlled problem in utilizing the scheme of technique for preparing gasoline by methanol.
The utility model is realized by following technical scheme, and a kind of preparing gasoline by methanol reactor comprises the tank body that has upper inlet and export down, is provided with at least two catalytic bed in tank body, is provided with the water cooler that connects tank body between catalytic bed.Water cooler is annular porous cold shock gas distributor.
Use and working process are, the mixture of methyl alcohol and dme or methanol vapor enter the upper inlet of preparing gasoline by methanol reactor described in the utility model, pass catalytic bed then from the top down successively, building-up reactions takes place in gas when passing catalytic bed, produce a large amount of heats simultaneously, again by water cooler with cooling gas such as N
2, O
2Or the gas of other not complete reaction sends in the reactor, and cold gas participates in reaction and circulation and the heat in the reactor is taken away.So just can make the entire reaction course safe and stable operation, cut down the consumption of energy, energy-conservation, saved investment.
Compared with prior art, preparing gasoline by methanol reactor described in the utility model can make methanol steam portion's direct reaction generation within it gasoline, LGP, and fuel gas.And the temperature that can guarantee catalytic bed is controlled within the desired temperature range at an easy rate.
