Waste of biomass gasification

生物质和废物作为中性碳的可再生来源受到了极大的关注。处理这些“新”原料的技术仍然基于传统的石化炼油厂工艺，需要适应被处理材料的新的和可变的性质。其中一种更清洁、实用、高效的技术是气化。在生物质和废物的情况下，气化涉及将固体碳氢化合物转化为不可冷凝气体，如CO和H2，用于燃烧（发电）和化学/燃料合成。生物质的水分和含氧有机物含量明显高于原油。这促进了气化炉内低温区不希望的粘性焦油形成。此外，生物质比原油含有更高的无机物、灰分和二氧化硅。这导致在生物质气化产品气体中过量形成不需要的颗粒。我们提出了一些创新的方法来处理生物质气化过程中的焦油和颗粒物。

Biomass and waste have received significant attention as renewable sources of neutral carbon. Technologies to process these "new" feedstocks are still based on traditional petrochemical refinery processes and need to adapt to the new and variable nature of the materials being processed. One of the cleaner, practical, and efficient of these technologies is gasification. Gasification, in the case of biomass and waste, involves converting solid hydrocarbons into non-condensable gases such as CO and H2 for combustion (electricity generation) and chemical/fuel synthesis. Biomass contains significantly higher moisture and oxygenated organic content than crude oil. This promotes undesirable sticky tar formation at lower-temperature zones within the gasifier. Further, biomass contains higher inorganic, ash, and silica than crude oil. This leads to excessive formation of undesired particulates in biomass gasification product gases. We are proposing several innovative approaches to deal with tar and particulates in biomass gasification processes.
