WebApr 16, 2004 · At a constant wall temperature and small initial pressures, the maximum rate of pressure increases reached a maximum, while, at high pressures, it decreased again. The position of this maximum depends on wall temperature and comonomer. Adding comonomers to ethylene decreases the maximum temperatures during decomposition … WebDec 1, 2009 · The effect of ethylene partial pressure and temperature on the hydrocarbon decomposition rate was studied. As a catalyst, a triply promoted iron catalyst (with addition of small amounts of potassium, calcium and alumina oxides) was used. The mean crystallites size was ca. 17 nm. The processes were performed using pure ethylene or …
