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 ...
Methyl acetylene (I) and propadiene (II) are prepared by gas-phase pyrolysis of diluted 3C hydrocarbon(s) (III) is carried o in a heating zone (HZ) divided into (i) a preheating zone, (ii) a pyrolysis zone and (iii) (I)/(II) formation zone. The preparation of methyl acetylene (...
METHOD FOR PRODUCING METHYL ACETYLENE AND PROPADIENEPROBLEM TO BE SOLVED: To provide a method for producing methyl acetylene and propadiene in good yield.SEKI KOHEI関 航平
2-Chloro-1-propene is prepared by catalytic hydrochlorination of methylacetylene and/or of propadiene in a liquid medium containing at least one catalyst chosen from compounds of the metals from group VIIIa and from the lanthanides, and at least one organic solvent capable of dissolving the ...
Process for the production of methylacetylene and propadiene in a reaction zone, of elongate shape along a direction (a), comprising a heating zone and a cooling zone, following said heating zone, in which is circulated in the heating zone, a gaseous mixture containing at least one hydrocarbon...
Liquid Phase Selective Hydrogenation Reaction of Methylacetylene and Propadiene in Propylene over Moderately Dispersed Palladium Catalysts, " Tadakuni Kitamura et al.

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 invention discloses a process for carrying reaction, rectifying and coupling to selectively hydrogenate to remove MAPD (Methylacetylene Propadiene) from refined propylene. A C3 fraction directly enters a propylene rectification tower or enters the propylene rectification tower after being pre-...
to 50° C. per {fraction (1/10)} of the length of the heating zone and at least one methylacetylene-propadiene formation zone in which the temperature climbs by about 70° C. to 150° C. per {fraction (1/10)} of the length of the heating zone, the products formed at the end ...
