Publication number: 20140165514Abstract: A particle separator for use in a conduit for removing solid particles from a particle-laden gas. The particle separator comprises a particle collecting chamber, an inlet port for directing the particle-laden gas into the particle collecting chamber, and an inner deflector positioned at least partially within the particle collecting chamber and downstream of the inlet port. The walls of the particle collecting chamber may include a protrusion protruding toward the inside of the particle collecting chamber cooperating with the inner deflector to recirculate the gas within the particle collecting chamber. The particle separator may also include a sump for storing solid particles that have been captured.Type: ApplicationFiled: December 20, 2012Publication date: June 19, 2014Applicant: Air Products and Chemicals, Inc.Inventors: William Robert Licht, Yu Zhang, Andrew Wilson Wang, Stephen Clyde Tentarelli

Patent number: 6069180Abstract: A process is set forth for converting synthesis gas into dimethyl ether (DME) in a single step comprising contacting the synthesis gas with a bifunctional catalyst system having a methanol synthesis functionality and a methanol dehydration functionality. In particular, the present invention is an improvement to said process for increasing the stability of the bifunctional catalyst system, particularly when the process is conducted in the liquid phase. The improvement comprises introducing a methanol containing stream into the DME reactor such that the methanol concentration throughout the DME reactor is maintained at a concentration greater than 1.0%, generally between 4.0% and 8.0%. In one embodiment of the present invention, the methanol containing stream comprises at least a portion of the byproduct methanol from the DME reactor such that said portion of byproduct methanol is introduced into the DME reactor as a recycle stream.Type: GrantFiled: December 17, 1998Date of Patent: May 30, 2000Assignee: Air Products and Chemicals, Inc.Inventors: Xiang-Dong Peng, Andrew Wilson Wang, Bernard Allen Toseland
