该文制备了3种固体超强酸催化剂用于直接液化,分别是Cl~-/ZrO_2、Cl~-/Fe_2O_3和Cl~-/ZrO_2-Fe_2O_3,研究直接液化催化剂对液化产物性能的影响;制备4种分子筛催化剂用于催化裂解,分别是HZSM-5、Fe~(3+)/HZSM-5、Co~(2+)/HZSM-5和Ni~(2+)/HZSM-5,研究催化裂解催化剂对裂解产物性能的影响。实验测定了催化剂的比表面积,进行了X射线衍射分析。直接液化产物的测定显示,Cl~-/ZrO_2的催化效果最好,其轻油混合相的酸值和羟值分别为26.55和404.56 mg KOH/g,重油相的酸值和羟值分别为30.84和206.63 mg KOH/g。催化裂解产物的测定显示,Fe~(3+)/HZSM-5的催化效果最好,其轻油混合相的酸值和羟值分别为27.71 mg KOH/g和320.27 mg KOH/g,重油相的酸值和羟值分别为14.35和294.97 mg KOH/g。催化剂的表征表明,7种催化剂均属于介孔材料,直接液化催化剂中,Cl~-/ZrO_2的比表面积最大;催化裂解催化剂中,Fe~(3+)/HZSM-5的比表面积最大。金属离子是以掺杂的形式位于HZSM-5晶体中,并没有呈现出独立的衍射峰即没有形成独立的金属氧化物。
Three solid superacid catalysts were prepared for direct liquefaction, Cl ~ - / ZrO_2, Cl ~ - / Fe_2O_3 and Cl ~ - / ZrO_2-Fe_2O_3 respectively. The effects of direct liquefaction catalyst on liquefaction products were studied. Preparation 4 The molecular sieve catalysts for catalytic cracking were HZSM-5, Fe3 + / HZSM-5, Co2 + / HZSM-5 and Ni2 + / HZSM- Effect of catalyst on the performance of pyrolysis products. The specific surface area of the catalyst was measured experimentally and the X-ray diffraction analysis was carried out. The determination of direct liquefaction products showed that the catalytic effect of Cl ~ - / ZrO_2 was the best, the acid value and the hydroxyl value of the light oil mixed phase were 26.55 and 404.56 mg KOH / g respectively, the acid value and hydroxyl value of the heavy oil phase were 30.84 And 206.63 mg KOH / g. The results of catalytic cracking showed that the catalytic effect of Fe 3+ / HZSM-5 was the best, and the acid value and hydroxyl value of the light oil mixed phase were 27.71 mg KOH / g and 320.27 mg KOH / g, respectively. The heavy oil phase Acid value and hydroxyl value of 14.35 and 294.97 mg KOH / g, respectively. The characterization of the catalyst showed that all of the seven catalysts were mesoporous materials. In the direct liquefaction catalyst, the specific surface area of Cl ~ - / ZrO_2 was the largest. The specific surface area of Fe ~ (3 +) / HZSM-5 was the highest in the catalytic cracking catalyst. The metal ions are in a doped form in the HZSM-5 crystal and do not exhibit an independent diffraction peak, ie no individual metal oxide is formed.
