Introduction of Research Institute of Petroleum Processing

The Research Institute of Petroleum Processing (RIPP),SINOPEC, is a comprehensive scientific research and devel-opment institute founded in 1956, engaging mainly in appliedtechnologies of petroleum refining and petrochemical pro-cesses (including crude assay, crude processing, petrochemi-cal technology, catalyst, petroleum and chemical industrialanalyzing, testing, evaluation and standardization, petrochemi-cal industrial automation, and computer application), and lay-ing stress on applie…     

Effect of the Structure of Cations and Anions of Ionic Liquids on Separation of Aromatics from Hydrocarbon Mixtures

1. Introduction Benzene is a key chemical in the chemical industry, used as the raw material for producing polymer precursors, solvents, dyes, drugs, herbicides, and so on. The world production of benzene is more than 2.0×107 tons/year (Vervalin, 1991; Weissermel and Arpe, 1993; Villaluenga and Tabe-Mohammadi, 2000). Before World War II, benzene was mainly produced from coal, but nowadays more than 90% is obtained from petroleum, mainly from catalytic reformates and FCC gasoline, and by …     

Molecular simulation of critical parameters of nano-confined n-alkanes

TraPPE force field combined with grand-canonical transition-matrix Monte Carlo simulation were used to investigate the vapor-liquid coexistence curve and critical properties of methane, ethane, propane, and n-butane in slit pores ranging from 6 ? to 40 ?. Long range correction for intermolecular potential in slit pore model was developed, and the fact indicating that its influence on various thermodynamic properties is not negligible was found. The simulation results show that the thermodynamic properties of nano-confined alkanes shift tremendously from the bulk state. The critical temperature under confinement experiences a roughly linear decrease with an inverse in the slit width, while the critical pressure and the critical density have a relative increment related with carbon number on both the large slit width region and the small slit width region. Further analysis on z-density profiles of alkanes revealed that the complex behaviors of shift in critical parameters are the results of interplay between fluid-fluid and fluid-wall interaction.     

Analysis of the Multinational Strategy of Oil Companies

With the continuous and rapid development of the national economy,China‘s oil consumption embarks on a stage of fast growth. The gap between oil supply and demand will get wider, which has seriously limited the development of China‘s economy and society.In 2004, China became the second largest oilconsumption country in the world,     

Mechanism of Combustion of Fuel‐Air Mixtures

A new mechanism of combustion of fuelair mixtures in internal combustion engines was formulated. According to this mechanism, a set of active particles: radicals, cation and anionradicals, ions, and electrons, participate in the combustion process.     

Characterization of Depositional System Tract for Exploration of Lithologic Pools-An example of Qaidam basin

System tract, a basic unit of Ⅲ-grade sequence, is a combination of the same-term depositional systems controlled by water level changes (lacustrine level or sea level). Petroleum tends to being accumulated in the depositional sand bodies of different system tracts. The type and distribution of lithologic pools could be predicted by characterization of system tracts and analysis of depositional systems. In southwestern Qaidam basin, the characterization of system tracts shows that there exist developed transgressive system tract (TST) and various types of reservoirs such as sand body of deltaic front, lacustrine beach and dam as well as local turbidite of semideep lake. Based on synthetically geologic and seismic analyses, using digital seismic processing techniques (Jason's reservoir inversion, etc.), the sand body distribution could be described, hence predicting that in southwestern Qaidam basin mainly developed the lithologic pools of SB, TU, DT and SS types.     

A Study of the Characteristics of Microorganisms for Effective Degradation of Marine Oil Spills

1. Introduction Crude oil is one principal organic pollutants in marine environments. It has been estimated that about (1.7~8.8)×106 tons of oil worldwide impact on marine water and estuaries annually (Head and Swannell, 1999). Oil spills have become a major concern in marine and coastal environments (Lei, et al., 2000). A number of means are available to clean up oil spills in the marine environment. Floating booms, skimmers, and oil-water separators are the most common mechanical means to…     

Preparation of VPO Catalysts and Effect of Zirconium Promoter on the Selective Oxidation of Pentane

1. Introduction The C5 cut, a relatively low-cost hydrocarbon stream in oil refining, has not found adequate use in petrochemical industry (Weissermel and Arpe, 1978). If it is used as liquid-petroleum-gas (LPG) component, the C5 cut is too heavy; while if it is used as gasoline component, the C5 cut is relatively too light. On the contrary, the demand for phthalic and maleic anhydrides is expected to grow at a rate of about 5% per year (Gleaves and Centi, 1993) due to their increasing app…     

Development Prospect of Oil ＆ Gas Pipelines of CNPC

Prospect of engineering technologies for pipelines in China
In recent years, China National Petroleum Corporation （CNPC） has made remarkable achievements in the field of oil and gas transmission pipeline engineering. The demand for oil and gas has increased a lot, along with the rapid development of national economy and the improvement of people＇s living standard. In the days to come, China will witness an even greater development in the engineering construction of oil and gas transmission pipelines.     

Control of Formation of Lithological Reservoirs by Surrounding Mudstone

1. Introduction The exploration for lithological reservoirs has become an key issue to find more oil reserves in the light of the increasing difficulties in hydrocarbon exploration in the mature basins in East China (Jia and Chi, 2004), especially in the Songliao Basin and Bohai Bay Basin. A lithological trap is defined as a trap enclosed or sealed by low porosity and low permeability rocks due to lithological change, which is caused by deposition and diagenesis as well as epidiagenesis (H…     

Effect of Sulfur on the Performance of Three-Way Catalysts

Sulfur content is one of the fuel properties to be monitored. Sulfur dioxide, the major product derived from organic sulfur compounds in the exhaust gas emissions, is a poison to the three-way catalysts (TWC). A gas mixture was applied to simulate the exhaust gases used in the TWC aging procedure tests. Two types of the TWC, REX-ⅡC and REX-ⅡD, were tested in this study. The performance of both TWC‘s before and after the 100-hour sulfur aging program was compared. It was concluded that the Pt component in the TWC was apt to bepoisoned by sulfur much easily than Rh. The performance of the REX-ⅡD catalyst was generally better than thatof the REX-ⅡC catalyst.     

Application of Microwave Technology for Desulfurization of Diesel Fuel

The microwave technology was introduced for the desulfurization of diesel fuel. The atmospheric second side-cut diesel fraction, which was supplied by Liaohe Petrochemical Company, was desulfurized by an oxidation process under microwave irradiation. Hydrogen peroxide (H202), can oxidize the sulfur compounds in diesel fuel selectively and convert them into sulfones. Based on the rule of dissolution by similar substances,these sulfones are removed from diesel fuel because they could be dissolved in solvent phase. So the sulfur content of diesel fuel is decreased. The influence of the concentration of oxidizing reagent, solvent phase to oil phase volume ratio (S/O), irradiation pressure, irradiation time, and the irradiation power have been investigated.The optimum conditions for the refining process was determined. The sulfur removal rate was 59.7% under the optimum conditions of 8%H2O2, S/O=0.25, 0.05MPa, 6 min, and 375W, respectively. When no microwave irradiation was applied, the removal rate was 11.5% only.
