Abstract: Disclosed are a mobile Internet-based integrated vehicle energy replenishment system and method, and a storage medium.

Abstract: Provided are a method and device for estimating the utility of replacement of a battery pack for an electric vehicle, and a charging management method and system based on the method and device. The method comprises the following steps: acquiring state data associated with a first battery pack and a second battery pack, the state data comprising usage history of the first battery pack and performance parameters of the first battery pack and the second battery pack; and determining a utility value according to the state data, wherein the utility value is used to characterize a degree of impact of an operation of replacing the first battery pack with the second battery pack on the service efficiency and service life of a battery pack set to which the first battery pack and the second battery pack belong. The method facilitates improving the service efficiency of a managed battery in a battery swap mode and extending the overall service life thereof.

Abstract: Provided are a liquid-phase hydroisomerization system and a process therefor and use thereof. The system comprises a gas-liquid mixer (3), a hydroisomerization reactor (4) and a fractionating column (6). An oil product and hydrogen are mixed as a liquid hydrogen-oil mixture, and are introduced into the hydroisomerization reactor for a hydroisomerization reaction, and after being fractionated, a target product is led out. A supplemental hydrogen-dissolving inner member is provided at least between a group of two adjacent catalyst bed layers in order to supplement hydrogen to the reactants. The process cancels a circulating hydrogen compressor, has a simple process flow, and can be applied to the production of a lubricant base oil by the hydroisomerization of a lubricant raw material or the production of a low freezing point diesel by the hydroisomerization of and the reduction in the freezing point of a diesel raw material.

Abstract: Provided are a distillate oil hydrogenation deacidification catalyst containing a molecular sieve, preparation and use thereof. In this catalyst, the weight of the catalyst, on the basis of 100%, is 1-5% magnesium calculated as an oxide, 1-20% alumino-phosphate molecular sieve and/or aluminosilicate molecular sieve; 1-10% Co and/or Ni; 5-30% Mo and/or W, and the balance is aluminium oxide. The catalyst is prepared through forming, dipping and baking. The catalyst is very active in hydrogenation deacidification, and also in hydrodesulfurization and hydrodenitrogenation.
