According to their present reserves, the resource volumes yet to be found and the large amount of non-conventional oil and gas resources, there is still great potential in oil and gas production. The proportion ofoil and gas in energy structure will be influenced by four major factors: 1) Potential of the world oil and gas resources; 2) Technological progress of oil and gas exploration and development; 3) Speed of the development of substitute energy resources; and 4) Variation ofoil price. It is estimated that, oil and gas will still retain an important proportion in energy structure by the first half of the 21st century.展开更多

However, the sole micro- pores in zeolites severely limit their applications in oil refining and natural gas conversion. To solve the problem, mesoporous zeolites have been prepared by introducing mesopores into the zeolite crystals in recent years, and thus have the advantages of both mesostructured materials (fast diffusion and accessible for bulky molecules) and micro- porous zeolite crystals (strong acidity and high hydro- thermal stability). In this review, after giving a brief introduction to preparation, structure, and characterization of mesoporous zeolites, we systematically summarize catalytic applications of these mesoporous zeolites as efficient catalysts in oil refining and natural gas conversion including catalytic cracking of heavy oil, alkylation, isomerization, hydrogenation, hydrodesulfurization, methane dehydroaromatization, methanol dehydration to dimethyl ether, methanol to olefins, and methanol to hydrocarbons.展开更多
