    • PURPOSE: A producing method of furfural is provided to reduce the manufacturing cost of the furfural by decreasing the catalyst loss rate, and by using a tungsten catalyst with chemical stability. CONSTITUTION: A producing method of furfural using xylose or hemicelluloses as a raw material comprises the following steps: converting the raw material into the furfural using a solid acid catalyst deposited with isopolytungstate to a zirconia supporting body in a reacting medium including supercritical fluid; and extracting and separating the furfural by spraying the supercritical fluid into the reacting medium The solid acid catalyst is formed depositing a isopolytungstate precursor to the zirconia supporting body and plasticizing the outcome at 700~1,200 deg C.
    • 目的:提供糠醛的生产方法,通过降低催化剂损失率,并通过使用具有化学稳定性的钨催化剂来降低糠醛的制造成本。 构成:使用木糖或半纤维素作为原料的糠醛的制造方法包括以下步骤:将使用异多钨酸盐沉积的固体酸催化剂的原料转化为糠醛至包含超临界流体的反应介质中的氧化锆载体; 并通过将超临界流体喷射到反应介质中来提取和分离糠醛。形成固体酸催化剂,其在氧化锆载体上沉积多异硫钨酸前体,并在700〜1200℃下塑化结果。
