PRODUCTION OF AQUEOUS COAL SLURRIES HAVING HIGH COAL CONTENTS |
摘要 |
Coarse coal particles are pulverized to at least 70% passing through a standard 200 mesh screen in the presence of water in an amount to form aqueous coal slurries having a coal concentration from 60 to 80% by weight. The pulverization is carried out also in the presence of polyether typed polyoxyalkylene adducts having a high molecular weight with polyols having at least three active hydrogen atoms, phenol/aldehyde condensates of polyalkyleneimines, or derivatives of these adducts. |
