  • Patent number: 10715789
    Abstract: A light-deflection three-dimensional imaging device and a projection device, and the application thereof are provided. The light-deflection three-dimensional imaging device includes a projection device, a receiving device and a processor. The projection device includes a light source, a grating, a condensing lens group, a light deflection element and an emission lens, wherein after the modulation by the grating, the aggregation by the condensing lens group and the deflection by the light deflection element, the projection light transmitted by the light source penetrates the emission lens and is emitted from a side surface of the projection device.

  • Patent number: 10639618
    Abstract: A method of wax oil hydrocracking includes the steps of pre-hydrotreating wax oil to obtain a pre-hydrotreated material flow; controlling the pre-hydrotreated material flow and a hydrogen-containing material flow to contact with a first hydrocracking catalyst to obtain a first hydrocracked material flow, and dividing the first hydrocracked material flow into a first hydrocracked material flow A and a first hydrocracked material flow B; controlling the flow B and a hydrogen-containing material flow to contact with a second hydrocracking catalyst to obtain a second hydrocracked material flow, and then separating and fractionating the second hydrocracked material flow to obtain a hydrocracked tail oil product; controlling the flow A, at least a part of the hydrocracked tail oil product, and a hydrogen-containing material flow to contact with a hydrogenation isocracking catalyst to obtain a hydrogenation isocracked material flow, and then separating and fractionating the obtained hydrogenation isocracked material

  • Patent number: 9017545
    Abstract: Disclosed is a process for hydrotreating inferior naphtha fraction, comprising: (1) warming a recycle oil in a heating device; (2) mixing the inferior naphtha fraction with the recycle oil before and/or after the heating device; and (3) feeding the mixture of the inferior naphtha fraction and the recycle oil into a separating unit, wherein the gas-liquid separation is realized at least to obtain a gas phase and a liquid phase, wherein the gas phase comprises gasified inferior naphtha, wherein the gas phase enters a hydrotreating reactor to undergo hydrotreating, and wherein part of the liquid phase circulates to the heating device as the recycle oil; wherein warming of the recycle oil is controlled to ensure the temperature of gas phase from the separator at least reaches the inlet temperature of the hydrotreating reactor. Comparing with the prior art, the inventive process effectively solves the coking problem of the hydrogenating unit for inferior naphtha fraction.

  • Patent number: 6526770
    Abstract: The present invention relates to temperature control for refrigerators, which automatically adjusts the on-temp/off-temp values in view of the fluctuation of the ambient temperature. The present invention also relates to a refrigerator on which a sensor of simplified circuit design is reasonably allocated. In accordance with the present invention, ambient temperature is divided into a plurality of particular temperature divisions, the on-temp and off-temp values preferred for refrigerator operation in each corresponding temperature division are determined by experiments. By means of a temperature sensor, on-temp/off-temp values appropriately corresponding to a particular temperature division are applied to keep the temperature of the refrigerator at a required level.
