    • A heavy fraction oil is catalytically cracked by contacting the oil with a catalyst containing an ultrastable Y-type zeolite, in a fluid catalytic cracking apparatus having a regenerating zone, a reaction zone, a separation zone and a stripping zone and under conditions that a reaction zone outlet temperature is in a range of 550 to 700.degree. C., a catalyst/oil ratio is in a range of 15 to 100 wt/wt, and a difference between a regenerating zone catalyst concentration phase temperature (1) and the reaction zone outlet temperature (2) is in a range of 5 to 150.degree. C. According to the fluid catalytic cracking process, an amount of dry gases generated by the thermal cracking of the heavy fraction oil can be lessened while a yield of light fraction olefins can be enhanced.
    • 在具有再生区,反应区,分离区和汽提区的流化催化裂化装置中,在反应条件下,使油与含有超稳定Y型沸石的催化剂接触,重馏分油被催化裂化 区出口温度在550〜700℃的范围内,催化剂/油比在15〜100重量/重量的范围内,再生区催化剂浓度相温度(1)与反应区 出口温度(2)在5至150℃的范围内。根据流化催化裂化过程,可以减轻由重馏分油的热裂解产生的干燥气体的量,而轻馏分烯烃的产率可以 加强。

    • Multiple component heart valves and apparatus and methods for implanting them are provided. The heart valve generally includes a first annular prosthesis and a second valve prosthesis. The first prosthesis includes an annular member compressible from a relaxed condition to a contracted condition to facilitate delivery into a biological annulus, the annular member being resiliently expandable towards the relaxed condition. The first prosthesis also includes guide rails extending therefrom. The second prosthesis includes an annular frame, valve elements, and receptacles for receiving respective guide rails therethrough when the second prosthesis is directed towards the first prosthesis. In addition, a valve holder may releasably carry the valve prosthesis that includes channels for receiving respective guide rails therethrough when the guide rails are received through the valve prosthesis. A delivery tool is also provided that includes an actuator for selectively compressing the annular member into the contracted condition.
    • 提供多组分心脏瓣膜及其植入装置和方法。 心脏瓣膜通常包括第一环形假体和第二瓣膜假体。 第一假体包括从松弛状态压缩到收缩状态以便于输送到生物环空中的环形构件,环形构件可朝向松弛状态弹性膨胀。 第一假体还包括从其延伸的导轨。 第二假体包括环形框架,阀元件和插座,用于当第二假体指向第一假体时,用于接收穿过其中的相应导轨。 此外,当保持导轨通过瓣膜假体时,阀支架可释放地承载阀门假体,该假体包括用于接收相应的导轨的通道。 还提供一种输送工具,其包括用于选择性地将环形构件压缩成收缩状态的致动器。
