A molecular sieve material, EMM-17, has in its as-calcined form, a total surface area of greater than 550 m.sup.2/g and/or an external surface area of greater than about 100 m.sup.2/g as measured by the BET Method, and a specific X-ray diffraction pattern.

A new crystalline molecular sieve designated SSZ-95 is disclosed. In general, SSZ-95 is synthesized from a reaction mixture suitable for synthesizing MTT-type molecular sieves and maintaining the mixture under crystallization conditions sufficient to form product. The product molecular sieve is subjected to a pre-calcination step, and ion-exchange to remove extra-framework cations, and a post-calcination step. The molecular sieve has a MTT-type framework and a H-D exchangeable acid site density of 0 to 50% relative to molecular sieve SSZ-32.

The present disclosure relates to a method for a simulated moving bed to adsorb and separate polycyclic aromatic hydrocarbons. Zeolite, metal oxide and metal-modified materials are employed as adsorbent. Firstly, diesel oil flows through pre-treatment adsorbent to remove the trace amount of impurities. Secondly, the purified diesel oil flows through the simulated moving bed so that the PAHs can be separated from diesel oil. In this process, the valves are switched periodically, leading to the relative movement of adsorption beds. At the same time, desorbent is pumped into the equipment to wash out PAHs, achieving the continuous adsorption-regeneration operation. Thirdly, simple distillation is employed to separate desorbent from clean diesel oil and PAHs, respectively. Finally, the fractions of clean diesel oil and PAHs can be obtained, respectively. The separated desorbent can be recycled. The PAHs removal rate can reach to 90%.

C. to remove impurities and oligomerize the oil; and b) hydroisomerizing at least a part of the product of step a). A lube base oil composition is also produced therefrom.

Method for the processing of a mixture of organic compounds, in particular of an oil, in order to recover different constituents therefrom. This method makes it possible to separate a fraction of iso-alkanes and cycloalkanes from a sample of a mixture of organic compounds, said method comprising a separation step by liquid chromatography.
