La mayor parte del pa\u00eds tiene carb\u00f3n resistido, Shanxi, Xinjiang, Mongolia Interior, Heilongjiang, Yunnan y Henan, parte de estos distritos tiene grandes reservas.<\/p>\n<p><span style=\"font-size: 14pt;\">Leonardita<\/span><\/p>\n<p>La leonardita tiene un alto contenido de ox\u00edgeno y un bajo valor calor\u00edfico. Y ha perdido el valor del combustible el\u00e9ctrico y el carb\u00f3n de coque. En general, la leonardita contiene una gran cantidad de \u00e1cido h\u00famico regenerado (HA) y una pluralidad de grupos funcionales activos que contienen ox\u00edgeno. Tales como grupo carbox\u00edlico, grupo hidroxilo fen\u00f3lico, grupo quinilo, grupo hidroxilo de alcohol y similares.<\/p>\n<p>Y el contenido de \u00e1cido h\u00famico del carb\u00f3n climatizado, que es generalmente de buena calidad, puede llegar a m\u00e1s del 50%. De modo que tambi\u00e9n se dota del nuevo valor de utilizaci\u00f3n del carb\u00f3n desgastado. El \u00e1cido h\u00famico es una parte org\u00e1nica importante de la mayor\u00eda del suelo.<\/p>\n<p>En la actualidad, la calidad del suelo en nuestro pa\u00eds es relativamente baja. La degradaci\u00f3n del suelo es mucho m\u00e1s grave. No solo el \u00e1rea degradada es grande, sino que tambi\u00e9n los fen\u00f3menos de erosi\u00f3n del suelo, desertificaci\u00f3n del suelo, acidificaci\u00f3n y salinizaci\u00f3n contin\u00faan expandi\u00e9ndose.<\/p>\n<p>Con el aumento de la contaminaci\u00f3n industrial y urbana, la contaminaci\u00f3n por metales pesados y la contaminaci\u00f3n org\u00e1nica del suelo se est\u00e1n volviendo cada vez m\u00e1s graves. La aplicaci\u00f3n de leonardita para la mejora del suelo no solo puede convertir los desechos en valor. Pero tambi\u00e9n puede mejorar efectivamente la degradaci\u00f3n del suelo y la contaminaci\u00f3n.
