早在20年代初期油团聚法就用于选煤。此后,又对各种方法进行了改进,但各种油团聚法有许多相似性,也有各自的特性。本文有三个目的。首先介绍各油团聚法所共有的物理-化学原理和工艺特点,其次是对各种发展较快的油团聚法进行比较 As early as the early 1920s, the oil agglomeration method was used for coal preparation. Since then, a variety of methods have been improved, but a variety of oil agglomeration method has many similarities, but also have their own characteristics. This article has three purposes. Firstly, we introduce the physical-chemical principles and technological characteristics common to all oil agglomeration methods, and secondly, compare the various oil agglomeration methods that are developing rapidly
