Abstract

A integrated biomass thermocracking equipment for preparing liquid fuel is composed of cyclone separator, carbon filter, multi-stage condensing system consisting of two air coolers, two heat-transfer oil heaters and three condensers, self-heating system consisting of two air coolers, carbon burner and heat exchanger of reactor, combined feeder, and cross-section variable fluidized-bed reactor. Its advantages are flash temp-rasing of biomass, fast eduction out of volatile components and recovering solid carbon.

Description

technical field [0001] The invention relates to a biomass integrated pyrolysis staged preparation device for liquid fuel. Background technique [0002] With the continuous development of my country's national economy leading to the rapid growth of energy demand, a large amount of SO emitted during the combustion and utilization of fossil fuels 2 , NO x Pollutants such as pollutants have seriously polluted the ecological environment. At the same time, as the world's second largest CO 2 Emitting country, CO 2 The "greenhouse effect" effect exacerbated by massive emissions has also been paid attention to in my country. In addition, due to the outbreak of oil crises and the instability of oil prices, the development and application of alternative liquid fuels has also been put on the agenda. Compared with fossil fuels such as coal, biomass is a renewable and clean energy resource, and because of the CO 2 The characteristic of zero emission has special signi...
