Furfural is obtained by pentosan dehydration after cracking in agricultural by-products after hydrogenation to get furfuryl alcohol under catalyst conditions. Furfuryl alcohol is the main raw material of furan resin which contains urea-formaldehyde furan resin, phenolic furan resin, ketoaldehyde furan resin, urea-formaldehyde phenolic furan resin. The resin is widely used in Casting production. Furfuryl alcohol can also be used as anticorrosive resin and pharmaceutical raw materials.
The catalyst and furfural are uniformly mixed in the measuring tank with the ratio of about 3 kg catalyst for every ton of furfural. The mixed materials are fed into the bottom of the reaction tower by measuring pump, which reacts with hydrogen at high pressure to produce furfuryl alcohol. Furfuryl alcohol is continuously discharged from the top of the tower and qualified furfural alcohol is prepared by distillation process.。
