Abstract

The invention discloses a method and device for removing particles in a biomass pyrolysis liquid ebullating bed reactor. The method comprises the following steps: A) primary cyclone classification to realize the classification of catalyst micropowder and catalyst particles; B) primary filtration Realize the separation of catalyst fine powder and transport oil; C) two-stage cyclone classification realizes the classification of structurally incomplete catalyst and structurally complete catalyst; D) two-stage filtration realizes the separation of structurally incomplete catalyst and transport oil; E) structurally complete catalyst and Fresh catalyst is mixed and added to the reactor for utilization. The invention also provides a particle removal device in the ebullated bed reactor of biomass pyrolysis liquid. The invention can meet the requirements of realizing the classification of particles and realizing the drying reduction of the separated catalyst, effectively avoiding the foaming and collision of the reactor bed caused by the fine powder of the catalyst, and reducing the risk of coking.

Description

technical field [0001] The invention belongs to the field of biomass energy and oil product processing, and relates to a method and device for treating micropowder, structurally incomplete catalysts and structurally complete catalysts in biomass pyrolysis liquid ebullating bed hydrogenation exhaust catalysts, and specifically relates to a A method and device for removing particles from a biomass pyrolysis liquid ebullated bed reactor. Background technique [0002] From the rapid pyrolysis process of straw and wood, biomass pyrolysis liquid products can be obtained; high-quality fuel oil can be obtained by hydrogenating them. Since the biomass pyrolysis solution is easy to condense and coke, and the catalyst life is short, it is advisable to use ebullating bed reactor technology to carry out hydrogenation upgrading. However, in the process of hydrogenation and upgrading of ebullating bed biomass pyrolysis liquid, due to the fully mixed flow circulation state in the reactor, ...
