The microwave pyrolysis system was used to study the effects of mixed additives on the microwave pyrolysis of Dunaliella salina. The mixed additive is a mixture of SiC and Na₂CO₃. The different weights of addition (5%, 10%, and 20%) of mixed additives, different mixing ratios (SiC:Na₂CO₃ = 0:10, 3:7, 5:5, and 6:4), and different kinds of additives (single additive and mixed additive) were studied. According to the findings, when the catalyst was 5% Na₂CO₃, the total weight loss (M_t) was maximum. The minimum M_t occurred at the 5% SiC group; when the mixed additive weight of addition was 10% and the mixing ratio of SiC:Na₂CO₃ = 5:5, the average weight loss rate (R_v) and weight loss rate for the first peak (R_p1) were maximum, and the time corresponding to the first peak (t_p1) was minimum. Besides, SiC and Na₂CO₃ had a cooperative action when the mixed additive weight of addition was 10% and the mixing ratio of SiC:Na₂CO₃ = 5:5. For the total electricity consumption in microwave pyrolysis and oil and gas production per unit of electricity consumption, the mixed additive group with the weight of addition was 10% and the mixing ratio of SiC:Na₂CO₃ = 5:5 was better.

混合添加剂对盐杜氏藻微波热解的影响

采用微波热解系统研究了混合添加剂对杜氏盐藻微波热解的影响。混合添加剂是SiC和Na ₂ CO ₃的混合物。混合添加剂的添加重量不同（5％，10％和20％），混合比例不同（SiC：Na ₂ CO ₃  = 0：10、3：7、5：5和6：4），以及研究了不同种类的添加剂（单一添加剂和混合添加剂）。根据发现，当催化剂为5％Na ₂ CO _3时，总重量损失（M _t）最大。最小M _t发生在5％SiC组; 当添加的混合添加剂重量为10％且SiC：Na ₂ CO ₃的混合比为 5：5时，平均失重率（R _v）和第一个峰的失重率（R _p1）最大，并且对应于第一峰值（t _p1）的时间最小。此外，当添加的混合添加剂重量为10％且SiC：Na ₂ CO ₃的混合比时，SiC和Na ₂ CO ₃具有协同作用。 = 5：5。对于微波热解的总电力消耗和每单位电力消耗的油气生产，具有添加重量的混合添加剂组为10％，并且SiC：Na ₂ CO ₃  = 5：5的混合比更好。
