摘要
研究了催化剂种类、浓硫酸催化剂用量、液化反应温度、苯酚与椰子壳质量比、液化反应时间对液化产物残渣率及结合酚的影响。结果表明,浓硫酸是椰子壳液化反应较佳的催化剂;当浓硫酸用量为6%,反应温度为150℃,质量比为4∶1时,液化反应30 min可较好地将椰子壳液化;随着液化反应时间的延长,液化产物结合酚含量上升。
The liquefaction of coconut shell in phenol was studied. The effects of catalysts, different content of sulphuric acid, reaction temperature, phenol ： powder ratio, reaction time on the content of residue and combined phenol of the products of liquefaction were discussed in detail. The result showed that sulphuric acid was an excellent catalyst. With 6% sulphuric acid （ the concentration of 98% ） as the catalyst, reaction temperature at 150 ℃, the weight ratio of phenol to coconut powder being 4, and reaction time 30 mins, favourable liquefaction reaction parameters were found. The amount of combined phenol rose with the reaction time extending.
