1) heavy hydrocarbon
重质烃
1.
ZrO_2 modified Co-Ru/γ-Al_2O_3 catalyst for synthesis of heavy hydrocarbons from syngas(Fischer-Tropsch synthesis)was prepared by impregnation method.
实验结果表明,随反应温度的升高,催化剂的催化活性提高,CH4的选择性增加,重质烃的选择性先增加后减小;升高反应压力有利于提高催化剂的催化活性、增加重质烃的选择性;增大气态空速不利于重质烃的生成;随n(H2)∶n(CO)的增大,CO的转化率和CH4的选择性增加、重质烃的选择性减小。
