生物质是自然界最丰富的含碳有机大分子功能体,它有望通过“生物炼制”实现“石油炼制”的辉煌。但是由于生物质资源本身及其转化过程的复杂性,生物质产业虽备受关注,却被认为是遥远的未来产业。传统的生物质资源化利用思路都是先耗费一定的能量破坏生物质结构,然后再进行转化,不仅没有考虑到产品的功能需求,而且过程的原子经济性不高。如何实现化学键更加复杂的固相木质纤维素生物质炼制是实现生物质产业的关键和难点。理想的生物质炼制的目的是以最大得率分离木质纤维原料中各个组分,以尽可能地保持分子的完整性,最大可能地优化利用和最终实现最大价值。这就要求生物质炼制应当是基于原料结构、过程转化和产品特点三者的关联,面向原料、面向过程、面向产品的炼制过程。本期专刊报道了我国生物质炼制技术领域专家学者在原料炼制、炼制技术、组分转化等领域取得的最新研究进展。
Biomass is the most abundant carbon-containing organic macromolecule function in nature and it is expected to realize the brilliant “petroleum refining” through “bio-refining”. However, due to the complexity of the biomass resource itself and its transformation process, the biomass industry is regarded as a distant future industry despite its concern. The traditional ideas of biomass resource utilization are to expend a certain amount of energy to destroy the biomass structure first, and then to convert it, not only failing to take into account the functional requirements of the product, but also the atom economy of the process is not high. How to Realize More Complex Chemical Bonds Solid-phase ligno-cellulosic biomass refining is the key and difficult point to realize the biomass industry. The goal of an ideal biomass refining is to separate the individual components of the lignocellulosic feedstock with maximum yield in order to preserve the integrity of the molecule as best as possible to optimize utilization and ultimately maximum value. This requires biomass refining should be based on the structure of raw materials, process conversion and product characteristics of the three related to the raw material, process-oriented, product-oriented refining process. This special issue reports on the latest research progress made by experts and scholars in the field of biomass refining technology in the fields of raw material refining, refining technology and component conversion.
