求翻译：高硅铝比的超细Y分子筛由于具有巨大的外表面，催化活性中心多，晶内扩散速率高以及良好的抗磨强度等特性，适应于渣油和重油的加工，在 FCC方面有广阔的应用前景。是什么意思？

Ultrafine y zeolite High-SiO2 Al2O3 Due to the huge outer surface, the catalytic active center, the intragranular diffusion rate is high and good abrasion resistance characteristics to adapt to the residual oil and heavy oil processing, in fcc applications.

High silicon aluminum than the ultra-fine Y molecular sieves with large outer surface, catalytic active center, crystal clear, high proliferation rate, as well as good resistance to wear and strength characteristics such as adapted to the residual and heavy oil processing, FCC in a broad application

Gao Guilv compared to because the superfine Y molecular sieve has the giant outside surface, the catalytic activity center are many, transgranular proliferation speed high as well as characteristics and so on good wear resistance, adapts in the residual oil and the heavy oil processing, has the broa

Superfine y-zeolite with high silica alumina ratio due to its huge appearance, activity center, Crystal high diffusion rate and good antiwear properties and other characteristics, suitable for residual oil and heavy oil processing, the FCC has broad application prospects.
