As the reserve of prime coking coal is low, there is a good amount of research going on worldwide to improve the coking potential of non-coking coal. Researchers have revealed the importance of hydrogen generation/transfer to improve the coking potential of coal. Based on this hypothesis, in this paper, the authors have tried to improve the coking potential of non-coking coal by adding different polymers. The polymers are derived from formaldehyde and phenol derivatives. Coking potential has been tested through conventional tests like crucible swelling number. Thermogravimetric mass spectroscopy (TG-MS) has been used to get an idea of plasticity and hydrogen generation in the plastic zone. High-temperature microscopy has also been used to evaluate the swelling of coal. Results indicate that the addition of polymers in a small percentage has an effect on hydrogen generation in the plastic zone, and thus, it can improve the coking potential of non-coking coal.

由于主要炼焦煤的储量较低，因此全世界进行了大量研究以提高非炼焦煤的炼焦潜力。研究人员已经揭示了氢气产生/转移对提高煤焦化潜力的重要性。基于这一假设，在本文中，作者试图通过添加不同的聚合物来提高非炼焦煤的焦化潜力。该聚合物衍生自甲醛和苯酚衍生物。结焦潜力已通过常规测试（如坩埚膨胀数）进行了测试。热重质谱（TG-MS）已用于了解塑料区域的可塑性和氢生成。高温显微镜也已用于评估煤的溶胀。
