20150324798 | POWER SUPPLY METHOD, BILLING PROCESSING METHOD, POWER SUPPLY SYSTEM, POWER SUPPLY CONTROLLER, POWER SUPPLY APPARATUS, POWER-SUPPLY CONTROL METHOD, MANAGEMENT SERVER, ELECTRIC VEHICLE, AND BILLING SERVE - A power supply system includes an authentication server. Before receiving power supplied from a power supply coil of a power supply apparatus, an electric vehicle is authenticated by the authentication server. For receiving power supplied from the power supply coil, the electric vehicle gives a power-supply request to request a power-supply controller, which controls the power supply apparatus, to issue a temporary ticket for receiving power supply. The electric vehicle transmits the temporary ticket to the power supply apparatus, and upon determining that the temporary ticket is legitimate, the power supply apparatus executes power supply. | 11-12-2015 |

20120310025 | Catalyst for Synthesizing 1-Hexene from Ethylene Trimerization and Application Thereof - A catalyst for synthesizing 1-hexene from ethylene trimerization and its application are provided. Said catalyst consists of (a) the compound containing P and N, (b) electron donor, (c) Cr compound, (d) carrier and (e) accelerator. The molar ratio of (a), (b), (c), (d) and (e) is 0.5-100:0.5-100:1:0.5-10:50-5000. The catalyst is prepared by mixing the components of (a)-(e) in an ethylene trimerization apparatus in situ and ethylene is introduced into the apparatus continuously. The prepared catalyst can be used to synthesize 1-hexene from ethylene trimerization in the inert solvents. The trimerization is performed at 30-150° C. and 0.5-10.0 MPa for 0.1-4 hours. The catalyst has high catalytic activity and high 1-hexene selectivity. During the process of ethylene trimerization, by-product polyethylene does not stick to the apparatus. | 12-06-2012 |

20130090508 | Method for Preparing 1-Octene by Oligomerization of Ethylene - Disclosed is a method for preparing 1-octene in the presence of a catalyst system for ethylene oligomerization, which includes: premixing a part of ethylene gas as raw material with a solvent, mixing with the components a+b, c and d of the catalyst system, and then sending in a reactor; directly sending the rest of ethylene gas in the reactor; discharging the resultant liquid from the upper part of the reactor into an overflow channel; adding a catalysis stopping agent to the overflow channel; and then separating the resultant liquid. The advantages of the method are high selectivity of 1-octene and high catalytic activity. | 04-11-2013 |
