The formation of 1,6-anhydrosugars and other main volatiles from catalytic pyrolysis of birch wood and lignocelluloses on it its base obtained by hydrothermal treatment at 150 and 180 °C was studied using Py-GC/MS/FID. Phosphoric acid and phosphorous-containing activated carbons, based on the carbonized residue from the levoglucosenone production, were used as the catalysts. The promising application of lignocelluloses as precursors for the pyrolysis for the levoglucosenone production is demonstrated. It is shown that P-containing activated carbon can be used for the levoglucosenone production in the same way as phosphoric acid. In the case of lignocellulose obtained at 180 °C yield of levoglucosenone was more than 20% calculating on raw material.

使用Py-GC / MS / FID研究了桦木和木质纤维素在150和180°C的水热处理得到的碱的催化热解过程中形成的1,6-脱水糖和其他主要挥发物。基于左葡糖醛酮生产中的碳化残留物，将磷酸和含磷活性炭用作催化剂。证明了木质纤维素作为热解的左旋葡糖醛酮生产的前体的有前途的应用。已表明含P的活性炭可以与磷酸相同的方式用于左旋葡糖醛酮的生产。对于在180℃下获得的木质纤维素，左葡糖酮的产率按原料计算大于20％。
