It has accumulatively fulfilled a contract value of US$2.363 billion in Sudan, Pakistan, Kazakhstan, Algeria, Venezuela and Syria and other countries and regions worldwide and has been repeatedly listed amongst the World＇s Top 225 International Contractors so far.展开更多

Pakistani President Pervez Musharraf, and his governmental officials including the minister of Petroleum and Resources attended the ceremony. In his speech, President Musharraf fully affirmed the significance of the WOPP project on promoting the national economy of Pakistan and guaranteeing the national energy security, highly praised the contributions to the successful execution of this project from the Chinese government and the company. President Musharraf also awarded project completion souvenirs and Outstanding Contribution Certificate to Sun Bo, president of CPECC, and Liu Xihui, director of the project.展开更多

Algerian President Abdelaziz Bouteflika presented at the ceremony with his governmental officials. Present were top managers of the project owner, Algerian State Oil Company （SONATRACH）, and Mr. Wang Yilin, Vice President of CNPC and CNPC delegation.展开更多

The results demonstrate that three basic nitrogencompounds, N1 （in which a molecule contains one nitrogen atom, similarly hereinafter）, N1O1 and N2, are identified bytheir positive-ion mass spectra, and three non-basic nitrogen compounds, N1, N1O1, and N1S1, are characterized by theirnegative-ion mass spectra. Among these nitrogen compounds, the N1 class species are the most predominant. Combinedwith the data of ESI FT-ICR MS and FT-IR, the basic N1 class species are likely alkyl quinolines, naphthenic quinolines,acridines, benzonacridines, while the abundant non-basic N1 class species are derivatives of benzocarbazole. In comparisonwith CGO, the N1 basic nitrogen compounds in VR exhibit a higher average degree of condensation and have much longeralkyl side chains.展开更多
