木材生物质是一种新能源的宝贵资源,其特点是能够再生。作为能源或热源,液态远比固态方便。至于木材,自然也以液态方式使用为好。1970年前后,美国矿山局进行了以纤维素材料为主的液化研究,其中包括废材、农业废料和城市废料等。将纤维素物料置于耐压容器中,用一氧化碳加压到4000磅/平方英寸,升温至350—400℃进行处理。反应中使用了许多种碱性催化剂,例如碳酸钾、碳酸钠、氢氧化铵和甲酸盐等,结果发现约90％纤维素发生了反应,得到40—50％的油份,进而把油转变成汽油和柴油的工艺也在研究中。在美国还有几家公司设了几套实验工厂装置,对纤维素质废物用一氧化碳液化进行了研究。装置的规模为1000吨/日干材,可以得到直接用的液化燃料617吨和其它产品。
Wood biomass is a valuable source of new energy and is characterized by its ability to regenerate. As a source of energy or heat, liquids are much more convenient than solids. As for wood, naturally it is better to use it in liquid form. Around 1970, the US Bureau of Mines conducted a liquefaction study that focused on cellulosic materials, including waste, agricultural and municipal waste. The cellulosic material was placed in a pressure vessel, pressurized to 4,000 psia with carbon monoxide, and heated to 350-400 ° C for treatment. As a result of the reaction of many basic catalysts such as potassium carbonate, sodium carbonate, ammonium hydroxide and formate and the like, about 90% of the cellulose was found to react to give 40-50% of the oil, which in turn converted the oil Processes into gasoline and diesel are also under study. There are several other companies in the United States that have set up experimental plant installations to study the use of carbon monoxide for liquefaction of cellulosic waste. The scale of the plant is 1000 tons / day of dry material, which can get 617 tons of liquefied fuel for direct use and other products.
