Abstract

The invention discloses an algal biomass continuous sectional catalytic pyrolysis reaction device which comprises an initial-section reaction device and a tail-section reaction device. The initial-section reaction device is formed by connecting a motor shaft with an initial-section spiral propeller positioned in an initial-section reactor, a gas incoming pipe is arranged on the initial-section reactor, a feeding device is arranged at an end close to a motor, and an exhaust pipe is arranged on the upper portion of the discharging end of the initial-section reactor; the tail-section reaction device is formed by connecting a motor shaft with a tail-section spiral propeller positioned in a tail-section reactor, an exhaust pipe is arranged on the upper portion of the discharging end of the tail-section reactor, and a collection container is arranged on the lower portion of the discharging end of the tail-section reactor. The discharging end of the initial-section reactor is connected with the feeding end of the tail-section reactor, so that sectional pyrolysis is realized during continuous feeding, a primary product semicoke is timely pyrolyzed further, convenience is brought to collecting products of every stage, and composition and physiochemical property of algal biomass pyrolysis products and combustion characteristics of bio-oil can be known more comprehensively.

Description

technical field [0001] The invention belongs to the field of bioenergy utilization, and in particular relates to a device for continuous segmental catalytic pyrolysis reaction of algae biomass. Background technique [0002] With the depletion of traditional fossil energy and the rapid growth of population and economy, biomass energy has gradually become the focus of research and utilization in all countries in the world. At present, the development of biodiesel and some alternative products of fossil energy using macroalgae is still a research topic. Hotspots and trends, macroalgae, as biomass, has the advantages of abundant reserves, rapid growth and reproduction, carbon neutrality in a short period of time, and no occupation of cultivated land. It is a high-quality alternative energy source. Biomass, as a renewable energy source, has a wide range of sources and has the prospect of replacing fossil fuels. Biomass rapid pyrolysis technology to produce bio-oil has attracted ...
