豆腐渣资源在近临界水中的分解动力学实验研究

Experimental study on the decomposition kinetics of TOFU waste resources on near-critical water condition

根据豆腐渣中的主要组分蛋白质、脂肪、纤维素、糖分等在近临界水中分解速度的不同 ,提出了一条豆腐渣资源化新工艺。该工艺包括豆腐渣在近临界水中分解、过滤和分离等工序。对近临界水中豆腐渣的分解动力学进行了研究。在该实验条件下 ,豆腐渣分解的表观活化能为 10 .2 k J/m ol。通过对分解产物的分析 ,初步确认了新工艺的可行性。

Based on the different decomposition rates among protein, fat, cellulose and saccharan, a new process to make full use of TOFU wastes was proposed, which includes continuous near critical water decomposition, filtering and separation. The kinetics of TOFU wastes decomposition in near critical water was studied. The apparent activation energy evaluated was 10.2 kJ/mol. From the analyses of the products, the feasibility of the new process was confirmed.
