Embodiment 1

[0038] CH 4 -CO 2 Two-step reaction step conversion direct synthesis of C 2 - Oxygenate improvements. CH 4 and CO 2 Co-activation and conversion is one of the most challenging topics in the field of catalysis integrating resources, energy and environmental protection. The present invention is very suitable for the above two-step reaction system.

[0039] Reaction principle: This process is a heterogeneous catalytic reaction system, and the catalyst (which can be regarded as an intermediate substance) is Co-Pd / TiO 2 , where TiO 2 as the carrier, Co and Pd as the catalytically active components, first catalytically activate CH 4 for CH X form, then pass into the CO 2 Carry out intercalation reaction to generate acetate group, generate acetic acid and ethanol after supplementing hydrogen.

[0040] Utilize device 1 of the present invention to carry out the small-scale experiment of this technique in laboratory, process flow sheet is as attached Figure 4 , solenoid valve...

Embodiment 2

[0044] Utilize device 2 of the present invention to carry out above-mentioned CH in the laboratory 4 -CO 2 The improvement experiment of the two-step reaction step conversion process, the process flow chart is attached Figure 5 , Reactors A and B are circulating beds, in which the catalyst is in a fluidized state, and the circulating beds A and B have a positioning difference. To illustrate from left to right, the hydrogen gas is decompressed and divided into two paths, and the flow rate is adjusted by the flow meter to connect with CH 4 and CO 2 mix, CH 4 First pass through the pressure reducing valve to reduce the pressure, then adjust the flow rate through the mass flow meter, enter the preheater, mix with hydrogen and water vapor, and then enter the circulating bed A for CH 4 activation of CO 2 After being decompressed by the pressure reducing valve, the flow rate is adjusted by the mass flow meter and then enters the preheater to mix with hydrogen and water vapor an...

Abstract

The invention discloses a continuous two-step reaction process and its reaction device, which is characterized in that two kinds of raw material gases can continuously enter the reactor without mixing after the reaction, and the process and device greatly improve the unit time The efficiency of the internal two-step reaction reduces the complexity of the operation, reduces energy consumption, manpower and material consumption. When used in CH4-CO2 two-step reaction step conversion to directly synthesize CO2-oxygenates, the efficiency can be increased up to 10-12 times compared with the original device.

Description

technical field [0001] The continuous two-step reaction process and its device of the present invention relate to a new type of chemical production device and process, which is suitable for the chemical process in which raw materials enter the reactor step by step for reaction. After activation, it reacts with another reactant to synthesize the chemical process of the product. technical background [0002] The two-step reaction process is a new type of reaction technology, which is suitable for the thermodynamically limited or thermodynamically unfavorable reaction process under the conventional co-feeding method. Its core idea is to split the thermodynamically unfavorable reaction into two steps: the first step , a reactant is reacted with an intermediary substance or catalyst to generate stoichiometric or non-stoichiometric compounds or adsorbed activated species, and then in the second step, another reactant is introduced to interact with these compounds or activated spec...
