Gas=liquid reactor for methyl formate prepn. - with improved dispersion of carbon mon:oxide, higher conversion and lower energy input.

摘要

Reactor construction, partic. for methyl formate synthesis, consists of a tubular housing, contg. circulation device. The novelty is that to simplify construction and to increase productivity (a) the circulation device takes the form of a fluid energy device (viz an educator), (b) the housing (1) contains a partition (2) below which the gas and liquid are fed, (c) the partition (2) has one or more orifices (20), (d) above the partition (2) and the orifices (20) there is a mixing chamber (3, 3a) arranged inside a tube (10), or several coaxial tubes (10a, 10b), (e) the mixing chamber (3, 3a) is closed at its upper end and (f) that the tubes (10, 10a, 10b) forming the mixing chamber (3, 3a) are perforated around their upper peripheries. USE/ADVANTAGE - Chemical reactor, partic. for production of methyl formate by the carbonylation of methanol. Improved dispersion of carbon monoxide within the reactor, providing higher conversion and requiring lower energy input.
