Ex-situ catalytic pyrolysis liquefaction system for biomass

Abstract

The invention relates to the technical field of conversion and utilization of biomass energy, in particular to an ex-situ catalytic pyrolysis liquefaction system for biomass. The ex-situ catalytic pyrolysis liquefaction system comprises a gasifier, a riser heater, a rotating cone reactor, a flow-guide cyclone reactor, a catalyst regeneration system, a gas-solid separator and a condensation system,wherein the bottom of the gasifier is connected with a first biomass feeder, and the upper part of the gasifier is connected with the lower part of the riser heater; a quartz sand feeder is connectedwith the lower part of the riser heater; the upper part of the riser heater is connected with an inlet of a quartz sand separator; the lower part of the quartz sand separator is connected with a heated sand box which is connected with an inlet of the rotating cone reactor; an outlet of the rotating cone reactor is connected with a gas inlet of the flow-guide cyclone reactor through a gas pipe; the flow-guide cyclone reactor is connected with a catalyst box at the upper part through catalyst inlets. An ex-situ catalytic pyrolysis process is performed on biomass with the system, operation is convenient and controllable, and working condition parameters in a pyrolysis process and a catalytic cracking process can be adjusted and controlled respectively.

Description

technical field [0001] The invention relates to the technical field of biomass energy conversion and utilization, in particular to a biomass non-situ catalytic pyrolysis liquefaction system. Background technique [0002] Fossil energy currently accounts for more than 80% of the world's primary energy supply, but because of its non-renewability and many environmental problems incidental to the development and utilization process, it has restricted the sustainable development of human beings. Therefore, the research on new energy has become an important field of energy development today. It can not only alleviate the dependence on fossil energy, but also have great significance for environmental protection and sustainable development of human society. It is an inevitable trend in the world. [0003] Among them, biomass energy uses plants with energy value and organic waste as raw materials. It has the characteristics of rich resources and renewable resources. It is currently t...
