A device for rapid reduction of deactivated catalyst

Abstract

The invention discloses a device for rapid reduction of deactivated catalysts, which belongs to the field of new energy research. In the device, an intelligent pulse impact machine and a gas distribution system are arranged in parallel between the control module, the NTP and the ionization generator, and the intelligent pulse impact machine and the gas distribution system are connected in parallel. There is also a voltage regulator between the NTP and the ionization generator; put the deactivated catalyst particles in the catalyst reduction unit, pass pure oxygen into the device, turn on the voltage control device, and apply voltage to the positive and negative electrodes of the composite high voltage electrode. , to generate active gas, and at the same time ionize the deactivated catalyst located in the electric field to break down the carbonaceous material in the internal pores. The temperature of the active gas is above 80°C, the active gas is enriched above, and the deactivated catalyst above is reduced. The stepper motor rotates to change the reaction position of the catalytic chamber in real time, reducing the incomplete reaction caused by catalyst accumulation and improving the reduction effect of NTP gas. The device of the invention can be continuously regenerated, has no secondary pollution, and has rapid, thorough and effective response.

Description

technical field [0001] The invention belongs to the field of new energy research, and in particular relates to a device for quickly reducing deactivated catalysts, which is used as a regeneration device for bio-oil cracking catalysts. Background technique [0002] With the continuous development of the world economy, a large amount of fossil energy has been continuously consumed, resulting in the depletion of energy and the increasingly serious environmental pollution. Abundant biomass resources have CO in the process of energy utilization 2 The net emission is zero, and the advantages of less SO and NO emissions. The technology of biomass pyrolysis to obtain bio-oil has been developed rapidly since it was proposed in the 1980s. However, due to the great difference in the physical and chemical properties of bio-crude oil and hydrocarbon fuels, its high water content, high oxygen content, high viscosity, low calorific value and other properties greatly hinder the wide use o...

AI Technical Summary

Problems solved by technology

Compared with the high-temperature roasting method, the regeneration time is shortened, but the ideal short-term effective regeneration cannot be achieved

Moreover, the utilization rate of ozone is not high, and the regeneration time is long.

[0006] Therefore, to overcome the defects and deficiencies of long regeneration time and low regeneration efficiency in the catalyst regeneration process, it becomes a key problem to be solved in the present invention
