Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for saccharifying cellulose using paper as a raw material face inhibition due to impurities like lignin and pitch, which also lead to contamination of the saccharification tank, making it difficult to maintain cleanliness and efficiency.
Innovation Solution
A method involving the introduction of a cellulose-containing raw material and an enzyme into a saccharification tank, with an adsorption sheet placed on the liquid surface to absorb oil components, preventing enzyme inhibition and maintaining tank cleanliness through efficient impurity collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If paper is used as a cellulose raw material, then cellulose saccharification can be performed, but impurities such as pitch and ink oil components inhibit the enzyme reaction and contaminate the saccharification tank
Solution Approach 1:
The patent extracts harmful impurities (oil components, pitch, lignin) from the reaction system by introducing an adsorption agent that selectively binds these substances and removes them from the reaction solution, thereby eliminating their inhibitory effect on the enzyme while preserving the cellulose saccharification process
Solution Approach 2:
The patent introduces an adsorption agent as an intermediary substance that mediates between the impurities and the enzyme system. The adsorption agent binds to harmful components through adsorption, preventing direct contact between impurities and the enzyme, thus protecting the enzyme reaction while allowing continuous saccharification
2Productivity
If paper is used as a cellulose raw material, then cellulose saccharification can be performed, but the saccharification tank becomes contaminated with sludge and oil components, making maintenance difficult
Solution Approach 1:
The patent extracts contaminants (sludge, oil components, pitch) from the reaction environment by using an adsorption agent that selectively binds these substances and removes them from the reaction solution, preventing accumulation on the tank walls and facilitating easier maintenance
Solution Approach 2:
The patent implements a self-cleaning mechanism where the adsorption agent continuously removes contaminants during the saccharification process itself, allowing the system to maintain cleanliness automatically without requiring separate intensive cleaning operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adsorption sheet effectively collects impurities, enhancing saccharification efficiency and maintaining tank cleanliness, resulting in improved saccharide production rates and easier tank maintenance.
Implementation Method 1
disposing an adsorption sheet on the liquid surface of the reaction solution, and decomposing the cellulose with the enzyme by stirring the reaction solution to produce a saccharide, the adsorption sheet adsorbing an oil component released from the raw material to the liquid surface of the reaction solution during the production of the saccharide

AI summary
A method for saccharifying cellulose includes introducing a cellulose-containing raw material and a reaction solution into a saccharification tank, introducing an enzyme into the reaction solution in the saccharification tank, disposing an adsorption sheet on the liquid surface of the reaction solution, and decomposing the cellulose with the enzyme by stirring the reaction solution to produce a saccharide. The adsorption sheet adsorbs an oil component released from the raw material to the liquid surface of the reaction solution during the production of the saccharide.
