The technology of coal tar hydrogenation for fuel oil has a very important significance in expanding application of coal tar in the energy field and solving the increasingly serious energy shortage. Developing a new sulfur resistance hydrogenation catalyst is the key to technology economic feasibility and large-scale application. This project aims to design, prepare a micro - mesoporous composite Pd-CeO2-CaO/ZSM-5/γ-Al2O3 hydrogenation catalyst with sulfur-tolerant-desulfurization model. Sol-gel and microwave heating is used to prepare mesoporous Al2O3. ZSM-5 structure unit is introduced into preparing ZSM-5/γ-Al2O3 with micro-mesoporous structure by crystallization. Load type Pd-CeO2-CaO/ZSM-5/γ-Al2O3 is prepared by volume dipping method, and the catalyst is used in coal tar hydrogenation reaction. H2S and 4, 6-dialkyl benzene thiophene as probe poisons for inorganic sulfur and organic are selected to study sulfur resistance properties and mechanism of the catalyst. The study explores synthesis and new functions of the micro-mesoporous materials. The research result has an important academic significance, it will promote crossover and fusion of the material chemistry, the catalytic chemistry and coal chemical etc, and will provide the scientific grounds and technical support to China's coal liquefaction technology solutions.
