Biomass continuous catalytic pyrolysis method for catalyst regeneration and integrated device thereof

Abstract

The invention discloses a biomass continuous catalytic pyrolysis method for catalyst regeneration and an integrated device thereof. The method comprises the following steps that a catalyst regeneration zone is heated in an oxygen-free environment, a pyrolysis zone and a tar removal zone of a vertical quartz tube, and a catalytic reforming zone receive corresponding radiant heat; the biomass is pyrolyzed in the pyrolysis zone to generate pyrolysis gas and biochar; the tar removal zone is composed of the biochar; the pyrolysis gas is subjected to tar removal, pyrolysis catalysis and condensationcollection; after the catalyst is deactivated in the catalyst regeneration zone, the catalyst is collected into a deactivated catalyst collection zone and is sent into a catalyst regeneration zone bya spiral feeder, so that the deactivated catalyst is regenerated and goes back to the catalyst reforming zone. Two processes of catalytic pyrolysis and catalyst regeneration which are generally separated are connected in the same set of device by the integrated device, so that the graded utilization of heat is realized, energy conservation and environment protection are realized, the integrated device can be widely applied to the field of biomass pyrolysis, and the application prospect is wide.

Description

technical field [0001] The invention relates to an integrated method for improving the efficiency of biomass catalytic pyrolysis, in particular to a catalyst regeneration biomass continuous catalytic pyrolysis method and an integrated device. Background technique [0002] With the improvement of people's living standards, the consumption of energy and the generation of waste are increasing day by day. On the one hand, fossil energy is depleted day by day, and on the other hand, the incomplete utilization of energy leads to the accumulation of waste. These two problems make the efficient and reasonable utilization of energy extremely urgent. Compared with non-renewable resources such as fossil energy, renewable biomass resources have broad prospects. Nowadays, biomass resources are abundant, but the technology for conversion and utilization is still immature, so exploring better means of biomass conversion and utilization is the direction that many researchers are working o...
