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。加工这些“新”原料的技术仍然基于传统的石化精炼工艺，需要适应正在加工的材料的新的和多变的性质。气化是这些技术中更清洁、实用和高效的技术之一。就生物质和废物而言，气化涉及将固体碳氢化合物转化为CO和H2等不可凝结气体，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。这会在气化炉内的较低温度区域促进不受欢迎的粘性焦油的形成。此外，生物质含有比原油更高的无机物、灰分和二氧化硅。这会导致生物质气化产品气体中有害颗粒的过量形成。我们正在提出几种创新的方法来处理生物质气化过程中的焦油和颗粒。

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.
