Abstract

Acrolein (C3H4O) is the simplest unsaturated aldehyde compound but is highly toxic and high reactivity due to the conjugation of a carbonyl group with a vinyl group. The uses of acrolein is protecting liquid fuels from microorganisms, making essential amino acid methionine and as a good separator and dispersing agent which is widely used in the ceramic, paper and electroplating industries. The acrolein plant is design to produce 36.000 tons/years. One of the main equipment in this plant is the dehydration reactor to react glycerol to produce acrolein. The type of reactor is fixed bed multitube reactor using WO3/ZrO2 as a catalyst at 410℃ and 1 bar in isothermal conditions. The glycerol flow rate is 21.088,193 kg/h and the cooling water flow rate is 113.891,47 kg/h. The height of reactor is 8,23 m and the diameter is 2,39 m with torispherical flanged and dished head and lug support.Keywords: acrolein, fixed bed multitube reactor, glycerol, zirconium.

Abstract

The decline in fossil fuel sources has prompted research into finding renewable fuels. One of environmentally friendly energy sources with high efficiency is by producing liquid oil from palm oil empty fruit bunch (EFB) and coal. Pre-treatment of empty fruit bunches using NaOH and various concentrations of H2O2, various ratios of EFB/coal, the ratio of CaO catalyst, chemical and physical characteristics were studied to produce the better liquid oil yield. The H2O2 concentrations are 0%, 1%, 2%, and 3%. The ratios of EFB/coal (R) are 0/100, 25/75, 50/50, and 75/25. The ratios of catalyst CaO/raw material are 0%, 3%, 6%, and 9%. It ran at 400 °C with 100 mL/min nitrogen gas flowing during one hour. The results showed that adding sodium hydroxide and hydrogen peroxide in the EFB pre-treatment increased the liquid oil yield. With an increase in the EFB/coal ratio, the liquid oil yield increased. Co-pyrolysis treated EFB and Coal with a ratio of 75:25 produced 32% liquid oil yield, but the liquid oil yield decreased to 19% with the addition of 9% CaO catalyst. However, the addition of CaO catalyst reduces the acidity and increases the calorific value of the liquid oil.
