摘要： Production of cumene by alkylation of benzene with propylene on a solid phosphoric acid catalyst, using a first step with a plurality of catalyst beds in series and a second step with a single catalyst bed, using an overall benzene/propylene molar ratio of at least 6:1, continuously delivering the benzene to the first bed, continuously delivering a series of streams of liquid propylene respectively to the first bed and, in the form of a cold stream, between each pair of contiguous beds, and using a benzene/propylene molar ratio higher than 16:1 at the inlet of each bed of the first step, and higher than 25:1 at the inlet of the bed of the second step.

摘要： Butyl rubber is prepared by polymerizing isobutylene and a conjugated diolefin in a liquid reaction medium wherein the temperature is controlled by indirect heat-exchange with boiling ethylene admixed with a gas which is inert towards ethylene, the said boiling ethylene being subjected to a controlled pressure maintained at a value not lower than atmospheric.
摘要翻译：丁基橡胶通过在液体反应介质中聚合异丁烯和共轭二烯烃来制备，其中温度通过与沸腾的乙烯间接热交换控制，该乙烯与对乙烯是惰性的气体混合，所述沸腾乙烯受到受控的压力保持值不低于大气压。

摘要： In a biological water purification process dirty water such as sewage percolates through a submerged bed of activated carbon under aerobic conditions, the carbon particle size and the water flow rate being such that the time of contact of the water with the mass of carbon above an intermediate level of the bed is at least thirty minutes, oxygenation air being blown into the bed at this intermediate level so that the mass of carbon below this level remains substantially free of active colonies of bacteria. The bed can be reactivated as desired by flushing with clean water and then with dirty water to re-establish bacterial colonies.
摘要翻译：在生物水净化过程中，污水如污水在有氧条件下通过活性炭浸没层渗滤液，碳颗粒尺寸和水流速使得水与中间物质质量接触的时间床的水平至少为30分钟，氧化空气在该中间水平下吹入床中，使得低于该水平的碳质量基本上不含活性细菌菌落。可以根据需要通过用清水冲洗然后用脏水重新建立细菌菌落来重新启动床。
