Abstract: According to an embodiment, a transfer system comprises a mobile body, a detection object, and a first detecting part. The mobile body is configured to travel and to transfer an object. The detection object is mounted to the object. The detection object is located at a higher position than the object when referenced to a surface on which the mobile body travels. The first detecting part is located at a higher position than the object when referenced to the surface. The first detecting part detects the detection object.

Abstract: The present invention relates to a medium-pressure hydrocracking process which uses a fresh hydrogen resource and a hydrosaturation catalyst with reduced metals of group VIB and/or group VIII as the active ingredients to selectively and deeply hydrosaturate jet fuel and/or diesel cuts derived in the medium-pressure hydrocracking process.

Abstract: The present invention relates to a highly active midbarrel hydrocracking catalyst and a process for the preparation thereof. The support of the catalyst comprises a modified zeolite-Y, a modified zeolite-&bgr;, alumina, etc. The composite of the modified zeolite-Y and zeolite-&bgr; exhibits a good synergistically catalytic effect. The catalyst prepared by supporting Group VIB and/or Group VIII metal components is useful in the hydrocacking of heavy oils with high content of sulfur and nitrogen to produce high quality middle distillates with maximum output. The activity of and selectivity to middle distillates of the catalyst are remarkably raised simultaneously. Moreover, the solidifying point of the produced diesel is remarkably lowered.

Abstract: The present invention discloses a medium-pressure hydrocracking process able to simultaneously produce products such as qualified gasoline, kerosene, diesel, etc.. Based on the prior medium-pressure hydrocracking process, the present invention uses a fresh hydrogen resource and a hydrosaturation catalyst with reduced metals of group VIB and/or group VIII as the active components to selectively and deeply hydrosaturate the jet fuel and/or diesel cuts derived in the medium-pressure hydrocracking, thereby allowing the quality of these cut fractions to meet the requirement of the specifications. In the present invention, a quite favorable reaction environment is created for the deep hydrosaturation of the jet fuel and/or diesel cuts with an extremely low investment by reasonable combination of the medium-pressure hydrocracking process flow, full reliance on the medium-pressure hydrocracking,, and addition of an ultra-low-pressure hydrosaturation reactor.
