盐肤木生物质炼制工程

Sumac(Rhus chinensis Mill) biomass refinery engineering

盐肤木为我国乡土植物,分布范围广,资源量丰富。盐肤木果实含有油脂,但含油量低,因此盐肤木是一种非典型油料植物,不能单独作为油料植物进行产业化开发。作者根据多年对盐肤木果实和枝桠梢头物料特性的研究,提出了以蒸汽爆破为核心技术的盐肤木生物质炼制新模式,提取的盐肤木果油申请了国家卫生部新资源食品并获得了新资源食品许可批文。以盐肤木资源为原材料,以蒸汽爆破技术为依托,集成不同组分分离技术,各组分分别进行功能转化,形成了盐肤木果油、生物柴油、蛋白饲料、黄酮、本色面巾纸、酚醛树脂、生物质成型燃料、沼气八大产品的盐肤木生物质炼制技术体系和生态产业链集成,为自然界中非单一经济型野生植物资源的开发提供了新的模式。

Sumac （Rhus chinensis Mill） is an abundant and widely distributed Chinese native plant. Sumac fruit contains low content of vegetable oil, as an atypical oil plants hardly being processed through traditional vegetable oil production technologies. Based on our own studies on the characteristics of sumac fruit and branches, we established a novel model of sumac biomass refinery, and constructed the sumac biomass refinery technology system and eco-industrial chain integration. Steam explosion was the key technology, and several components fractionation technologies were integrated in the sumac biomass refinery system. The fractionated components were converted into different products depending on their functional features. Eight products including sumac fruit oil, biodiesel, protein feed, flavonoids, unbleached facial tissue, phenolic resin, biomass briquette and biogas were produced in the refinery. The extracted sumac fruit oil by steam explosion pretreatment was applied for the new food resource of Ministry of Health, and the permit was approved. This research provides a new model for the development of atypical wild plant resources.
