is hindered because there is no Explanation: The whole sentence is somewhat convoluted. Could you simplify it? Perhaps something like: "Therefore, widespread use of brown coals, long-flame coals and lean coals, all of which are noncaking coals, in coke production is hindered because there is no process by which to produce coke from such coals that would ensure the desired quality." |
