Embodiment

[0072] Example: take the laboratory experiment of the alkylation reaction of nonene and phenol with this simulated adiabatic device as an example to further illustrate. See the reaction scheme for the reaction of nonene with phenol to form nonylphenol.

[0073] First, carry out laboratory research, determine the reaction law, and establish a mathematical model according to the reaction law. This step is the basis of all the work, and the data about the law of reaction obtained in this step will become the basis for establishing mathematical models in the future. According to the experimental plan and laboratory preliminary research results, the relationship between reaction temperature, material ratio and conversion rate was determined, the catalyst was determined to be cationic resin catalyst Amberlyst15, the single tube consumption was 15g, and the operating variables were reactor inlet and outlet temperature, Distribution ratio, to determine the effect of the manipulated v...

Abstract

An experimental method and apparatus for simulating the adiabatic reaction in laboratory is characterized by that the miniature single-tube reactor is used and solid bed layer of catalytic reactor is heated according predictated value to generate an artificial temp gradient. It is suitable for the strong heat releasing reaction (alkylation, oligorization, or hydrogenation).

Description

technical field [0001] The invention relates to a laboratory simulation adiabatic reaction experimental technology, in particular to an experimental method for simulating a chemical synthesis adiabatic reaction, and a corresponding experimental device. [0002] The "laboratory simulated adiabatic reaction experiment technology" conceived by the present invention enables researchers to obtain the basic data for the design of an industrial reaction device for adiabatic reaction in the laboratory by using small and micro single-tube reactors. According to the pre-estimated bed temperature rise or temperature drop of the solid catalytic reactor, the present invention artificially creates a temperature gradient in the reactor to make the reaction proceed under the simulated adiabatic condition. Then compare the obtained test results with the laboratory target value, and correct the temperature gradient setting value according to the size of the deviation, and repeat this process fo...
