BEIJING, July 25 (Xinhua) -- The following is a summary of published science and technology news of China.


Chinese researchers have developed a new method of sieving propylene from propane, promising to improve the efficiency of propylene production.

Traditional industrial technology of sieving propylene from propane usually comes at a cost of high investment in equipment and huge energy consumption.

Researchers at Jinan University developed a new method using orthogonal-array dynamic molecular sieving, which is energy-saving and will greatly improve production efficiency.


China's first ultra high-voltage (UHV) power superhighway for transmitting clean energy delivered 13.1 billion kWh of power from the Qinghai-Tibet Plateau, abundant in energy resources, to densely populated Henan in central China, according to State Grid's Qinghai branch.

As the world's first all-clean energy UHV power transmission project, the 800-kilovolt direct current transmission line became operational on July 15, 2020. It extends 1,563 km across four provinces.

It is a pilot project aiding China's pursuit of attaining carbon dioxide emissions peak before 2030 and achieving carbon neutrality before 2060.
