    摘要： Solid particles are coated in a fluidized bed by application of a gaseous coating agent from a plasma, wherein the plasma is generated outside the fluidized bed under 0.01-500 mbar, and the plasma-activated gas is passed into the fluidized bed, which is operated under 0.1-500 mbar, wherea. the plasma is generated from the total amount of gaseous coating agent with or without another gas, orb. the plasma is generated from a portion of the gaseous coating agent with or without another gas, and the remaining portion is introduced directly into the fluidized bed, orc. the plasma is generated from another gas, and the total amount of gaseous coating agent is introduced directly into the fluidized bed.

    摘要翻译： 通过施加来自等离子体的气态涂层剂将固体颗粒涂覆在流化床中，其中在0.01-500毫巴下在流化床外部产生等离子体，并且等离子体活化气体进入流化床，其被操作 低于0.1-500毫巴，其中a。 等离子体由具有或不具有另外气体的气体涂覆剂的总量产生，或b。 等离子体由具有或不具有另一种气体的一部分气态涂覆剂产生，并且剩余部分直接引入流化床，或c。 等离子体由另一种气体产生，气态涂料的总量直接引入到流化床中。
