The results showed that both LPG and propylene yields were increased, and propylene selectivity was improved after the incorporation of P or M into the matrix, resulting in an increased C3 to C4 ratio in LPG during FCC process. But the sole incorporation of M into the matrix also led to an increase in coke and H2 yields on the other hand. Simultaneous modification of the matrix by P and M components resulted in more enhancement in propylene yield and selectivity along with little influence on FCC product distribution. Physico-chemical characterizations and model compound reactions were used to assist in analyzing the mechanism for improving propylene selectivity. Two types of active centers could strengthen the oligomerization of C4 olefins in LPG and these oligomers could be further cracked into C3 olefins on ZSM-5 zeolite, therefore maximizing the ratio of C3 to C4 in liquefied petroleum gas obtained during FCC process.展开更多

After reviewing the achievements and summarizing the problems of the oil and gas industry in China, this paper lays emphasis on the key aspects of this new round of deepening reforms, and holds rite position that this reform, based on the implementation of the national energy strategy, covers the entire oil and gas industry chain by liberalizing market access, reforming market mechanisms, and strengthening management. The reform will bring far-reaching effects upon the entire chain and the participants of the oil and gas industry. It will help to improve the market-oriented allocation of resources, allow enterprises to interact as competitors, and enhance the national oil and gas security.展开更多
