The extraction of fiber from plants is usually used in the manufacture of pulp, which produces a large amount of alkaline black liquor and poses a serious threat to the environment.

A few days ago, the "green biomass biomass separation and extraction" technology developed by Beijing Dream Fox Yutong Bamboo Fiber center has passed the appraisal conference organized by the China high tech Industrialization Research Association.

Chairman of the appraisal committee,

Ding Fuchen, a professor at the Institute of petrochemical technology, said that the technology was "zero pollution, zero discharge" and high utilization rate, and the comprehensive level reached international advanced level.

It is reported that "green biomass biomass separation and extraction" technology is to solve.

Low strength and heavy pollution during extraction.

Without water, using mixed catalytic solvents, only 30 minutes to 2 hours can effectively separate all biomass from woody and herb.

Ding Fuchen said that the newly developed organic solvent system containing catalyst and biomass separation and extraction technology can separate and extract cellulose, hemicellulose and lignin from biomass. It has high utilization rate of raw materials, recyclable solvents, less water consumption, low comprehensive energy consumption, no waste liquid, waste gas and waste residue, environmental protection and low investment in equipment, and the high yield and purity of the "three element" products obtained from separation and extraction, and the quality of products meets the relevant standards after testing.

Zhang Ziyu, the Beijing Dream Fox Yutong Bamboo Fiber Research and development center, said that using new technology to separate and extract new high purity lignin, because of its unique technology and physical properties, it could extend the development of a wide range of high-tech products, involving aerospace, military, solar energy, microelectronics and other fields. Lignin can also become an almost endless renewable energy and resources of biomass. The extracted cellulose can be used as textile raw materials, pulp and building materials industry, etc. hemicellulose (pentose) is an important pharmaceutical, food and chemical raw material.
