✦ Synopsis

Reactants

and reaction intermediates of significant volatility will distribute themselves between the liquid and vapor phases to a degree determined by relative flow rates, liquid holdup and other variables. This in turn can affect conversion and selectivity. The effects in the catalytic hydrodenitrogenation (HDN) of quinoline were noticeable but not marked because the overall HDN reaction is only marginally greater than zero order. The enhancing effect of H2S was the same in an all-vapor and a vapor-liquid system. KEYWORDS Trickle-bed reactor; hydrodenitrogenation; quinoline; hydrogen sulfide% vapor-liquid flow ratio; vapor phase versus liquid phase reaction.
