Device and method for reforming biomass tar to produce syngas

Abstract

The invention discloses a device for reforming biomass tar to produce syngas. A solar transmission window (1) of the device is arranged at the upper part of the device, and has an arch-shaped structure; a catalyst loading plate (4) is arranged below the solar transmission window (1), a material inlet (2) and a material outlet (3) are respectively located in two ends of a space located between thesolar transmission window (1) and the catalyst loading plate (4), the upper surface of the catalyst loading plate (4) is filled with catalyst particles, and the lower surface of the catalyst loading plate (4) is provided with heating tubes (5); and a heating medium is introduced into the heating tube (5). The biomass tar reforming process is characterized in that under solar radiation, a compositecatalyst having photocatalytic properties and thermal catalytic properties is utilized to prepare the syngas through CO2 reforming of the biomass tar, so that conversion efficiency of preparing the syngas from the biomass tar can be improved, resource utilization of greenhouse gas CO2 can be realized, and consumption of non-renewable resources in the tar conversion process can be significantly reduced.

Description

technical field [0001] The invention relates to a device and a method for converting biomass tar, belonging to the field of utilization of biomass resources. Background technique [0002] Biomass gasification is one of the important ways of thermochemical conversion and utilization of biomass. The synthesis gas produced can be used not only as gas fuel, but also as an intermediate product of chemical products. Therefore, biomass gasification technology has important practical application value. However, the tar that cannot be eliminated in the biomass gasification products not only reduces the efficiency of biomass gasification, but also seriously affects the normal operation of downstream equipment, which restricts the commercial application of biomass gasification technology. The focus of biomass gasification technology research. In recent years with the CO 2 The global climate change caused by the massive emission of greenhouse gases is becoming more and more severe, an...
