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

Abstract

The invention discloses a biomass microwave catalytic pyrolysis method for catalyst regeneration and an integrated device thereof. The method comprises the following steps that solid residues generated after a biomass enters a pyrolysis zone for pyrolysis reaction become biochar, pyrolysis gas is subjected to tar removal through a biochar layer, and enters a catalytic zone provided with a catalystfor further pyrolysis catalysis. The pyrolysis zone, the tar removal zone, the catalytic reforming zone and the catalyst regeneration zone are mainly heated by a microwave heating device, the heat radiated from the catalyst regeneration zone is used as auxiliary heat, and the pyrolysis zone, the tar removal zone and the catalytic reforming zone receive radiant heat to ensure that the pyrolysis zone, the tar removal zone and the catalytic reforming zone can rapidly and stably reach a set temperature value. 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 the field of biomass catalytic pyrolysis, in particular to a biomass microwave catalytic pyrolysis method for catalyst regeneration and an integrated device thereof. 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 on. [0003] There are many d...
