摘要： The present invention provides a process for continuous treatment of high-concentration organic wastewater and a device for continuous treatment of high-concentration organic wastewater. The process of the present application is that: high-concentration organic wastewater is continuously separated through the synergistic interaction of a multilayer evaporator and a heat pump, and the generated wastewater steam containing light components is continuously subjected to desulfurization and catalytic combustion after being mixed with air in a gaseous form, the treated wastewater can meet discharge standards, and heavy components of the generated wastewater can be recycled. After the desulfurizing agent in a first desulfurizer and the catalyst in a first catalytic combustor are deactivated, the generated wastewater steam containing the light components can be switched to a second desulfurizer and a second catalytic combustor for reaction, and air can be introduced into the deactivated catalyst and desulfurizing agent for in-situ regeneration at a high temperature.

摘要： A device and a process for producing undecylenic acid methyl ester using methyl ricinoleate as raw material are provided. The device comprises a feed pump, a raw material pre-heater, a microwave catalytic reactor, a microwave generator, a temperature controller and an infrared sensor, a condenser, a product tank and a discharge pump. The feed pump is connected with the raw material pre-heater, which is connected with the inlet of the microwave catalytic reactor. The outlet of the microwave catalytic reactor is connected with the condenser, which is connected to the product tank and the discharge pump. The microwave catalytic reactor is located in the microwave generator, which is connected with the temperature controller and the infrared sensor. The process is as follows: high-purity methyl ricinoleate, used as the raw material, is converted to methyl undecene and heptaldehyde by microwave-assisted pyrolysis process, followed by isolation and purification to produce methyl undecene.
