  Fiber-reinforced composite polyurethane foams(PUF)were prepared using oleic-based polyester polyol and bamboo fiber.At the first stage,oleic acid was converted to hydroxyalkanoate as a new type of polyol by epoxidation,modification and esterification.At the second stage,PUF were prepared with bamboo fibers.The effects of fiber size,fiber content,alkali treatment on the apparent density,mechanical property,thermal property of composite foams were investigated.In the case of application of 30-55mesh alkali modified bamboo fibers in the amount of 5 php(per hundred polyol),the foams sample has highest values of compressive and flexural strength.The thermal stability of the PUF was improved with the addition of modified bamboo fiber.

作为高污染高碳的能源品种,煤炭在支撑中国经济高速发展的同时也带来了日益严重的环境污染、温室气体等问题。在大气污染防治政策不断升级,而天然气供应明显不足的情况下,由热解煤气制备天然气,既可以实现能源的清洁高效利用,又可平衡天然气的供需关系。一些由钙钛矿前驱体制得的催化剂具有很好的水煤气变换反应催化活性以及甲烷化催化活性,同时具有高温耐受性,应用于相对高温、含有焦油成分的热解荒煤气体系,既可以去除其中
