    • The invention relates to a method for converting an oxygenated hydrocarbon feedstock into an olefin product comprising: (a) forming a CHA framework type aluminosilicate sieve catalyst made from a substantially fluoride-free synthesis mixture comprising silicon and aluminum sources, a slurry medium, and a template, wherein the sieve is substantially free from framework phosphorus and exhibits a Si/Al ratio from about 40-60; (b) optionally formulating the molecular sieve catalyst with an oxidized aluminum-containing precursor matrix material and a clay binder to form a molecular sieve catalyst composition; (c) activating the catalyst by removing/decomposing the template; and (d) contacting the activated catalyst with the feedstock under conditions sufficient to form an olefin product comprising ≧about 65% by weight, on a water-free basis, of ethylene and propylene and having an ethylene-to-propylene ratio ≧about 1.2. Ethylene- and propylene-containing polymers can be formed from the olefin product.
    • 本发明涉及一种将含氧烃原料转化成烯烃产物的方法,包括:(a)形成由基本上不含氟化物的合成混合物制成的CHA骨架型硅铝酸盐筛催化剂,其包含硅和铝源,浆料介质和 模板,其中所述筛基本上不含框架磷并且表现出约40-60的Si / Al比; (b)任选地用氧化的含铝前体基质材料和粘土粘合剂配制分子筛催化剂以形成分子筛催化剂组合物; (c)通过去除/分解模板来活化催化剂; 和(d)使活化的催化剂与原料在足够的条件下接触,所述条件足以在无水基础上形成包含≥65重量%的乙烯和丙烯并且乙烯与丙烯之比≥约1.2的烯烃产物 。 含烯烃和含丙烯的聚合物可以由烯烃产物形成。

    • A broadhead arrow sharpening accessory adapted to receive a flat file between end blocks for sharpening the broadhead blades. The end blocks contain end slots formed therein for receiving the ends of the file. Parallel rods extend between the end blocks alongside the side edges of the flat file. Support carriages are slidably mounted on the rods for receiving the broadheads with a blade extending outward frictionally engaging a file surface. The carriage and broadhead are moved in unison along the rod with the blade edge frictionally engaging the filing surface to sharpen the blade edge at the desired bevel angle.
    • 一种宽头箭头磨刀配件,适用于在端块之间接收平面文件,用于磨削宽幅刀片。 端块包含形成在其中的端槽,用于接收文件的端部。 平行的杆在平面文件的侧边缘之间的端块之间延伸。 支撑托架可滑动地安装在杆上,用于接收具有向外摩擦地与文件表面接合的刀片的宽头。 托架和宽头杆沿着杆一致地移动,刀片边缘摩擦地接合到压片表面,以便以期望的斜角角度锐化叶片边缘。
