    Abstract: A process for the production of hydrogen cyanide comprises feeding a reaction mixture feed to a plurality of primary reactors each comprising a catalyst bed comprising platinum, wherein the reaction mixture feed comprises gaseous ammonia, methane, and oxygen gas, determining whether a percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below a threshold, identifying one or more suboptimal reactors amongst the plurality of primary reactors when the percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below the threshold, and supplementally feeding the reaction mixture feed to one or more supplementary reactors when the one or more suboptimal reactors are identified, wherein each of the one or more supplementary reactors comprises a catalyst bed comprising platinum. The supplemental feeding can be performed in place of the feeding of the reaction mixture feed to the one or more suboptimal reactors or in addition to the feeding of the reaction mixture feed to the one or more suboptimal reactors. The overall process is sufficient to maintain an overall measured hydrogen cyanide production rate amongst the one or more supplementary reactors and the primary reactors that is within a desired overall hydrogen cyanide production rate range.

    Abstract translation: 一种生产氰化氢的方法包括将反应混合物进料加入至包含铂的催化剂床的多个初级反应器中，其中反应混合物进料包括气态氨，甲烷和氧气，确定氢的百分比产率 在多个初级反应器中的任何一个反应器中的氰化物处于或低于阈值时，鉴定多个初级反应器中的任何一个中的氰化氢的百分比产率处于或低于阈值时，在多个初级反应器中识别一个或多个次优反应器， 以及当鉴定出所述一个或多个次优反应器时，将所述反应混合物进料补充进料至一个或多个辅助反应器，其中所述一个或多个辅助反应器中的每一个包括含有铂的催化剂床。 可以进行补充进料，代替反应混合物进料进料至一个或多个次最佳反应器，或者将反应混合物进料进料至一个或多个次最佳反应器。 整个方法足以在一个或多个辅助反应器和初级反应器中保持在所需的总体氰化氢生产速率范围内的总体测量的氰化氢生产速率。

    Abstract: Disclosed are processes for application of dyes and topical chemistries to single yarns during a yarn rewind process. The process foregoes the need for downstream environmentally unfavorable dyeing and low PH chemical treatment processes on the finished carpet. Further, neutral pH dye solutions can be used instead of the prior art low pH dye solutions. The single, treated yarn can then be twisted, weaved and tufted, twisted yarn under dry conditions, and the twisted yarn subsequently weaved or weaved and tufted, into a finished fabric or carpet. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed processes.

    Abstract translation: 公开了在纱线回绕过程中将染料和局部化学物质应用于单纱的方法。 该方法放弃了对成品地毯上的下游环境不利染色和低PH化学处理过程的需求。 此外，可以使用中性pH染料溶液来代替现有技术的低pH染料溶液。 然后可以在干燥条件下将单一经处理的纱线进行扭曲，编织和加捻，加捻纱线，然后将加捻纱线编织或编织并成簇成为成品织物或地毯。 还公开了由通过所公开的方法处理的BCF纱线制成的系统，BCF纱线和地毯。
