Patent number: 8025774Abstract: 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 a primary transfer line exchanger to quench the process effluent comprising olefins, separating in a first separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to a 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 carrying out such process is also provided.Type: GrantFiled: July 20, 2009Date of Patent: September 27, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: James N. McCoy, Barrington M. Hammond, David J. Duhon, Mark A. Rooney, Robert D. Strack, John R. Messinger

Patent number: 5254785Abstract: 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.Type: GrantFiled: June 9, 1992Date of Patent: October 19, 1993Assignee: Exxon Chemical Patents Inc.Inventors: David D.
