Provided are a liquid-phase hydroisomerization system and a process therefor and use thereof. The system comprises a gas-liquid mixer (), a hydroisomerization reactor () and a fractionating column (). 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.
