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.

The present invention relates to a method for preparing a sulfur-resistant catalyst for aromatics saturated hydrogenation, comprising the steps of: preparing noble metal impregnation solutions from a noble metal and deionized water or an acid solution; impregnating a carrier with the impregnation solutions sequentially from high to low concentrations by incipient impregnation; homogenizing, drying, and calcinating to obtain the sulfur-resistant catalyst for aromatics saturated hydrogenation. The catalyst for aromatics saturated hydrogenation prepared by the method according to the present invention is primarily used in processing low-sulfur and high-aromatics light distillate, middle distillate, atmospheric gas oil, and vacuum gas oil. The method according to the present invention is advantageous in that the catalyst for aromatics saturated hydrogenation exhibits good hydrofining performance, superior aromatics saturation performance, high liquid yield of products, as well as excellent desulfurization and sulfur-resistance, and the catalyst has remarkable effects in use and a great prospect of application.
