Either raising the cokingtemperature or prolonging the coking time results in change of the coking mechanism, and the deposited coke tends to show a particle like morphology.
提高结焦温度或延长结焦时间，结焦机制发生转变，焦炭形貌也逐渐转变为颗粒状。

Factors affecting coking at the bottom of the fractionator are composition of slurry, temperature, catalyst content and residence time.
影响分馏塔底结焦的因素有分馏塔底油浆的组成、温度、催化剂含量及停留时间。
