    • An improved process is disclosed for the selective disproportionation of toluene. The process preferably uses a disproportionation catalyst comprising a pentasil type zeolite such as MFI that is bound with aluminum-phosphate. Running the process at a toluene conversion greater than 30 wt-% and at a hydrogen-to-hydrocarbon ratio less than 3.0, and especially a ratio of 0.1 to 1.0, improves the maximum yield of para-xylene. Periodic rejuvenation by increasing the hydrogen-to-hydrocarbon ratio removes some carbon deposits and restores catalyst activity. An inert diluent gas assists in selective pre-coking of the catalyst as well.
    • 公开了用于甲苯选择性歧化的改进方法。 该方法优选使用包含五氮烷型沸石的歧化催化剂,例如与磷酸铝结合的MFI。 以大于30重量%的甲苯转化率和低于3.0的氢 - 烃比,特别是0.1至1.0的比例运行该方法提高了对二甲苯的最大产率。 通过提高氢与烃的比例来定期回复除去一些碳沉积物并恢复催化剂活性。 惰性稀释气体也有助于催化剂的选择性预焦化。

    • A process for controlling a refinery or chemical process has been developed. The process comprises flowing a feed conduit (206) to a processing unit (222); operating on the feed stream to generate an effluent stream (242); flowing the effluent stream (242) away from the process unit; passing at least a portion of the feed stream or the effluent stream through a catalytic alloy hydrogen sensor (212) and generating a signal corresponding to the concentration of hydrogen present in either the feed stream or the effluent stream; passing the signal to a display unit; and adjusting an operating parameter (232) of the process in response to at least the signal generated by the catalytic alloy hydrogen sensor (212). The display unit may be part of a computer (230) which automatically adjusts an operating parameter. The catalytic alloy hydrogen sensor (212) may be a palladium-nickel catalytic alloy hydrogen sensor.
    • 已经开发了用于控制炼油或化学过程的方法。 该过程包括使进料管道(206)流动到处理单元(222); 在进料流上操作以产生流出物流(242); 使流出物流(242)离开处理单元; 使至少一部分进料流或流出物流通过催化合金氢传感器(212)并产生对应于存在于进料流或流出物流中的氢气浓度的信号; 将信号传递到显示单元; 以及响应于至少由催化合金氢传感器(212)产生的信号来调整该过程的操作参数(232)。 显示单元可以是自动调整操作参数的计算机(230)的一部分。 催化合金氢传感器(212)可以是钯镍催化合金氢传感器。
