In this study, an effort was performed to improve methylacetylene and propadiene (MAPD) hydrogenation process with investigation of operating conditions which significantly influence the reactor performance. For this purpose, the operational parameters including concentration of components in the feedstock as...
The present invention provides a process for removing methyl acetylene and/or propadiene from a propylene stream and/or a butylene stream by two step fractionation. Methyl acetylene and/or propadiene avoids the use of a hydrogenation reactor and makes the methyl acetylene and/or propadiene ...

Liquid C3 hydrocarbon mixtures are purified to remove methylacetylene and propadiene by passing a solution of hydrogen in the liquid through a reactor containing a hydrogenation catalyst so that the reactor remains filledwith liquid. Hydrogen is dissolved by bubbling into the liquid or spraying the ...
