    • A catalyst suitable for the high pressure gasification of heavy hydrocarbons to produce methane-containing gases is a calcined coprecipitated-alumina containing from 50- 65% Ni on a calcined unreduced basis. The catalyst contains (1) from 0 to not more than 0.43% K and from 0 to not more than 0.1% Na, (2) the combined weights of Na+ K does not exceed 0.011 gm atoms/100 gm of catalyst, (3) the ratio of Na:K falls within the area defined by ABCDEO in FIG. 1 of the drawings and (3) at combined Na+ K weights of from 0 to 0.05% the water loss is not more than 11.2%.The catalysts are prepared with the aid of a filtering aid selected from (NH.sub.4).sub.2 CO.sub.3, Na.sub.2 CO.sub.3, K.sub.2 CO.sub.3, Na NO.sub.3 or K NO.sub.3 to obtain low levels of alkali in the precursor. The catalyst may be employed for steam reforming reactions to produce methane-containing gases.
    • 一种催化剂前体当被还原时可以产生适合于重烃气体高压气化产生含甲烷气体的催化剂,它包括含有50-65%Ni前体的煅烧共沉淀氧化铝。 催化剂含有(1)0至不大于0.43%K和0至不超过0.1%的Na,(2)Na + K的组合重量不超过0.011gm原子/ 100g催化剂,前体( 3)Na:K的比例落在图1中由ABCDEO定义的区域内。 (3)组合Na + K重量为0〜0.05%,失水量不超过11​​.2%。 催化剂前体借助于选自(NH 4)2 CO 3,Na 2 CO 3,K 2 CO 3,NaNO 3或KNO 3的过滤助剂来制备,以获得低水平的碱。 最终催化剂可用于蒸汽重整反应以产生含甲烷的气体。

    • In a process for preparing phosphoric acid by contact of sulphuric acid and phosphate rock with filtration of the gypsum slurry and recycle of the rest for contact with fresh rock, a fraction of the recycle slurry is treated with sulphuric acid to convert at least some of the gypsum to calcium sulphate hemihydrate and the slurry comprising hemihydrate is returned to contact the mixture of phosphate rock, phosphoric acid and recycle gypsum slurry. The process gives an easily filtered gypsum slurry with low phosphate losses in the gypsum filter cake.
    • 在通过硫酸和磷酸盐岩接触制备磷酸的过程中,过滤石膏浆料和再循环剩余部分与新鲜的岩石接触,一部分循环浆料用硫酸处理以将至少一些 返回石膏至硫酸钙半水合物,并且将包含半水合物的浆料返回以与磷酸盐岩,磷酸和再循环石膏浆料的混合物接触。 该方法在石膏滤饼中提供容易过滤的具有低磷酸盐损失的石膏浆料。

    • A storm drain system is provided. The storm drain system incorporates a vertical grate and embodies a method of adapting the vertical grate for allowing sufficient water flow through a vertical opening portion of a storm drain while filtering out debris that would otherwise flow through the vertical opening portion, polluting waterways the storm drain fed into. The vertical grate providing a plurality of intersecting members across the vertical portion for filtering the debris, and helping prevent backed up drains which could render the storm drain ineffective during heavy rains.
    • 提供雨水排放系统。 雨水排放系统采用垂直格栅,并体现了一种适应垂直格栅的方法,以便允许足够的水流过暴风雨的垂直开口部分,同时过滤掉否则将流过垂直开口部分的污染物,污染水道雨水泄漏 喂入。 垂直格栅跨越垂直部分提供多个相交构件,用于过滤碎片,并且有助于防止在大雨期间使得风暴排水不起作用的后备排水。
