The invention provides a method for synthesizing a mesoporous zeolite ETS-10 containing a metal without a templating agent. The method according to the invention comprises the steps of: mixing a silicon source with a NaOH solution to obtain a mixed solution so that the content of NaO in the mixed solution is 10.0% to 20.0% by weight; adding a KOH or KF solution so that the content of KO is 10.0% to 25.0% by weight and stirring it well; adding a titanium source solution and stirring it well; adding a precursor compound containing metal Ni and/or Co and stirring it well; and subjecting it to a crystallization reaction to obtain the mesoporous zeolite ETS-10. The mesoporous zeolite ETS-10 obtained by the invention has a specific surface area of 320 to 420 m/g, a mesoporous volume of 0.11 to 0.21 cm/g, and thus can be used as a catalyst and a support thereof in synthesis industry for macromolecular fine chemicals.

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.
