Guangdong Private Enterprises Break Through Key Technologies of Clean Utilization of Lignite

At the beginning of June, Zhaoqing Shunxin Coal Chemical Technology Co., Ltd. in Zhaoqing National Hi-tech Industrial Development Zone successfully passed the “Development of a New Process for the Comprehensive Utilization of Hot-Soluble Catalytic Processes for the Comprehensive Utilization of Lignite” technology. The identification of the composition of the appraisal committee.

Experts commented that this technology will take a critical step forward in the clean utilization of large amounts of stored lignite in China.

It is understood that as of the end of 2007, the national coal reserves identified nearly 1,200 billion tons, and lignite resources accounted for about 1/7. It is understood that due to the characteristics of high water content, low calorific value, difficulty in storage and transportation of lignite, it has not reached a large-scale development and utilization for a long period of time. It can be described as “it is a pity that food is tasteless and abandoned”.

The Shunxin coal chemical technology identified by the domestic appraisal committee in the pilot test will change all this. Experts of the appraisal committee believe that the project started with the study of lignite, which was previously considered to be of low value. Under mild conditions, it was graded and converted to obtain 33% of oil, 37% of coke, and 22% of gas. "The results have reached the international advanced level." Ni Weidou, director of the appraisal committee and academician of the Chinese Academy of Engineering, said.

Some experts said that the results are expected to solve the world's difficult problems of lignite classification and utilization. It is predicted that the results will be put into large-scale production, equipment investment is only 1/3 of the traditional liquefaction technology, the total investment is only 1/2 of the traditional liquefaction technology, and the economic benefits are very considerable.

Ni Weidou suggested that when the project opened up a new road for the use of lignite in the world, the industry chain based on the project is very long and the Shunxin coal chemical project should be realized as soon as possible. “If the key technology breaks through, go ahead and go quickly.” Wu Kewang, head of the coal chemical industry, said: "If it goes well, it is expected to start production within three years of industrialization."

Stereo Light Curing Molding - Sla

STEREO LIGHT CURING MOLDING - SLA
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.
