摘要： The present invention provides a process for cracking or decomposing a feedstream containing a major proportion of at least one dialkyl ether to produce the corresponding olefins comprising contacting the feedstream with a faujasite aluminosilicate catalyst which is characterized in that at least about 50 wt. % of the alkali metal content originally present in said faujasite has been exchanged by at least one alkaline earth metal. The decomposition is preferably conducted in the vapor phase at preferred temperatures in the range of from about 125.degree. F. to about 600.degree. F. The process offers the advantages of longer catalyst life coupled with high yield and selectivity rates towards olefin production.
摘要翻译：本发明提供了一种裂化或分解含有主要部分至少一种二烷基醚的进料流以产生相应的烯烃的方法，包括使进料流与八面沸石硅铝酸盐催化剂接触，其特征在于至少约50wt。原来存在于八面沸石中的碱金属含量的％已被至少一种碱土金属交换。分解优选在气相中在优选的温度范围为约125°F至约600°F下进行。该方法具有延长催化剂寿命以及对烯烃生产具有高产率和选择性速率的优点。

摘要： In a system for thermal cracking gaseous feedstocks, the system including a gas cracker for producing an effluent comprising olefins, at least one transfer line exchanger for the recovery of process energy from the effluent and a water quench tower system, a process for extending the range of system feedstocks to include liquid feedstocks that yield tar is provided. The process includes the steps of injecting a first quench fluid downstream of the at least one transfer line exchanger to quench the process effluent comprising olefins, separating in a separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to the water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for cracking a liquid hydrocarbon feedstock that yield tar is also provided.
