Design and construction of a reactor for in situ infrared studies of catalytic reactions

摘要: Transmission infrared spectroscopy is a very useful technique for characterizing the structure of adsorbed species present on catalyst under reaction conditions. Reactors conducting such in situ studies have been described by number authors. The details simple reactor which can be used to study catalytic reactions at moderate temperatures (<573 K) and elevated pressures are described. has low dead volume short optical path length, built fashion that windows samples replaced quite easily. here hydrogenation CO up 573 K as high 2.4 MPa. No problems encountered with either extended operation or cycling temperature between 373 K. upper limit operating 590 set Kalrez O-rings. pressure not clearly established.
