China is imposing heavy restrictions on the construction of future power plants that will use petroleum coke for more than 20 percent of fuel in a national effort to control air pollution, the National Energy Administration said in a Dec. 22 notice. The notice states that petroleum coke-fired power plants have high carbon, high sulfur and heavy-metal emissions, and that while future construction will be restricted nationwide, the most strict approval processes would be in the three key air pollution control regions. That includes around the Beijing-Tianjin-Hebei region; Shanghai and the Yangtze River Delta; and the Pearl River Delta in southern Guangdong province.
