Progress Ontechnology of Biomass Gasification

针对现阶段气化工艺和系统的落后和效率低的问题,生物质气化技术能有效的解决。采用工艺集成和组合的方法可以实现更高的工艺效率,更好的气体质量和纯度,并且投资成本较低。生物质气化、热产气净化和调节系统的紧凑型UNIQUE气化工艺为技术创新提供了发展的机会。热解和气化可以独立控制,也可以在一个多级气化过程中联合控制。用于生产多种能源产品的多联产工艺路线具有高效率和灵活性。

In view of the low efficiency of gasification at this stage,the technology of biomass gasification technology can solve it effectively. The method for process integration and combination can achieve higher process efficiencies,the quality and purity of gas will be better,and the investment costs will be lower. The recently developed UNIQUE gasifier which integrates gasification,gas cleaning and conditioning in one reactor unit is an example for a promising process integration. Combine pyrolysis and gasification or gasification and combustion in single controlled stages. Poly-generation strategies for the production of multiple energy products offer high efficiency and flexibility.
