DEHYDROGENATION PROCESS AT REDUCED HYDROGEN TO HYDROCARBON RATIOS

DEHYDROGENATION PROCESS AT REDUCED HYDROGEN TO HYDROCARBON RATIOS

Processes for dehydrogenation of a hydrocarbon feedstock are described. The process can be run at lower H2/HC ratios and lower RITs while maintaining coke production at the same level as operation at higher H2/HC ratios and higher RITs without decreasing the yield per pass. Acceptable levels of coke...

Zusammenfassung:Processes for dehydrogenation of a hydrocarbon feedstock are described. The process can be run at lower H2/HC ratios and lower RITs while maintaining coke production at the same level as operation at higher H2/HC ratios and higher RITs without decreasing the yield per pass. Acceptable levels of coke were achieved when operating the process at low hydrogen to hydrocarbon molar ratio in the range of 0.01 to 0.40 and reactor inlet temperatures in the range of 500°-645° C.
