    • The process relates to the recovering of essentially pure acetylene from the gaseous out-put stream from a coal to acetylene conversion process. A plasma arc generator or other high energy type reactor can be used for the conversion to coal. The gaseous out-put stream is initially treated in an acid gas removal stage by absorbing HCN and H.sub.2 S in an organic solvent such as N-methyl pyrrolidone and scrubbing with a caustic agent such as NaOH to remove CO.sub.2. In a second stage, the gaseous out-put stream is scrubbed with the organic solvent to provide a sweet gas treatment and remove essentially pure acetylene as a product. In a third stage, the second stage gases are first hydrogenated, then desulfurized and then methanated. The out-put from the third stage is recycled to the coal to acetylene conversion process. In a fourth stage, the organic solvent from said second stage is refined and recycled to the first stage and/or second stage.
    • 该方法涉及从煤从乙炔转化过程的气体输出流中回收基本上纯的乙炔。 等离子弧发生器或其他高能型反应器可用于转化为煤。 气体输出流最初在酸性气体去除阶段通过在有机溶剂如N-甲基吡咯烷酮中吸收HCN和H 2 S进行处理,并用苛性剂如NaOH洗涤以除去CO 2。 在第二阶段,用有机溶剂洗涤气体输出流,以提供甜味气处理,并除去基本上纯的乙炔作为产物。 在第三阶段,第二阶段的气体首先被氢化,然后脱硫然后进行甲烷化。 从第三阶段的出口回收到煤炭到乙炔转化过程。 在第四阶段,将来自所述第二阶段的有机溶剂精制并再循环至第一阶段和/或第二阶段。

    • A method of making a catalytic lead-based oxygen-evolving anode comprises catalytically activating titanium sponge particles larger than 300 microns by impregnating with a solution containing Mn and Ru compounds, in amounts corresponding to Mn/Ru in an atomic ratio between 70/30 and 90/10, and thermally converting the compounds to an electrocatalyst comprising Mn and Ru in oxide form. Catalytic Ti sponge particles with up to 3 wt % Ru are thus produced, which are then uniformly distributed on the surface of a lead anode base in an amount greater than 400 g/m.sup.2, pressed, and partly embedded, thereby firmly anchoring and electrically connecting them to the lead anode base. The catalytic lead-based anode thus produced operates with oxygen evolution on the catalytic particles at a reduced potential at which the lead base remains electrochemically inactive. It thereby operates with significant energy savings over an extended service life.
    • 制备催化铅基放氧阳极的方法包括通过用含有Mn和Ru化合物的溶液浸渍而以大于300微米的钛海绵颗粒催化活化,其量相当于Mn / Ru,原子比为70/30和 90/10,并且将化合物热转化成包含氧化物形式的包含Mn和Ru的电催化剂。 因此产生具有高达3重量%Ru的催化钛海绵颗粒,然后将其均匀分布在铅阳极基底的表面上,其量大于400g / m 2,压制和部分嵌入,由此牢固地锚固和电连接 他们到铅阳极基地。 如此生产的催化性铅基阳极在催化剂颗粒上以降低的电位产生氧气而导致铅基保持电化学活性。 从而在延长的使用寿命期间显着节省能源。
