The traditional zeolite LTL is hard to possess fine properties both the adsorption and the activity of catalysis for big organic compounds. Here, we report that hierarchical structured LTL zeolites were prepared using a post-treatment technique with microporous, mesoporous and macroporous. The as-prepared samples were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM）, Transmission electron microscopy（TEM）, nitrogen adsorption,Temperature-programmed-desorption of ammonia（TPD-NH3） and Fourier Transform Infrared Spectroscopy（FTIR）. Meanwhile, the hierarchical structured LTL zeolites were used to carry out catalytic cracking reaction of 1, 3, 5- isopropyl benzene and n-hexadecane. Data showed that this modified LTL displayed improved catalytic activity and selectivity than that of traditional LTL,ZSM-5, Beta, Al-MCM-41, etc.

Based on polychaete specimens collected from coastal areas of China in 1959, a new species of the family Orbiniidae, Leodamas sinensis sp. nov. is described in the present paper. The new species can be distinguished from its cogeners by the combination of following characters： branchiae present from chaetiger 5; each thoracic neuropodial postchaetal lobe possessing broad tori, with a digital to triangular-shaped papilla at its midlength; 4 or 5 vertical rows of uncini and one posterior row of accompany capillaries in thoracic neuropodia; acicula present in both abdominal notopodia and neuropodia, slightly or distinctly projecting. A key to all known species of the genus is provided.
