    • A method for producing continuously 100% mesophase composed only of Q.I. component and Q.S. component in which a raw material of petroleum origin pitch is subjected continuously to a heat-treatment step in an amount necessary to produce a 100% mesophase taken out from a mesophase-growing and coalescing step, transferring the heat-formed pitch formed in the heat treatment step to a mesophase growing and coalescing step, taking out a definite amount of a non-mesophase pitch from the mesophase growing and coalescing step after stirring and heating treatment to return it to the heat-treatment step to repeat the stirring and heating treatment, and at the same time to take out 100% mesophase having constant properties from the mesophase growing and coalescing step.
    • 连续生产仅由Q.I.组成的100%中间相的方法。 组件和Q.S. 其中将石油来源沥青的原料连续地进行到从中间相生长和聚结步骤中取出的产生100%中间相所需量的热处理步骤的组分,转移在热量中形成的热成形沥青 处理步骤进行中间相生长和聚结步骤,在搅拌和加热处理之后从中间相生长和聚结步骤中取出一定量的非中间相沥青以将其返回到热处理步骤以重复搅拌和加热处理, 同时从中间相生长和聚结步骤中取出具有恒定性能的100%中间相。
