Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adsorbents containing diatomaceous earth and a basic compound experience a decrease in adsorption performance due to crystallization of the basic compound, which reduces the effective surface area for acid gas adsorption.
Innovation Solution
Incorporating a saccharide, such as glucose, into the adsorbent composition, along with diatomaceous earth and an alkali metal carbonate as the basic compound, to suppress crystallization and maintain adsorption performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a basic compound is supported on diatomaceous earth to create an adsorbent, then the adsorbent can remove acid gases, but the basic compound undergoes crystallization which decreases the effective surface area and reduces adsorption performance
Solution Approach 1:
A saccharide is introduced as an intermediary substance between the basic compound and diatomaceous earth. The saccharide forms a complex with the basic compound that prevents crystallization, thereby maintaining the effective surface area while preserving acid gas adsorption capability
Solution Approach 2:
The chemical state of the basic compound is changed by forming a complex with saccharide. This parameter change prevents the basic compound from undergoing crystallization, thereby maintaining its adsorption performance over time
2Quantity of substance
If the basic compound is used in high concentration to enhance adsorption capacity, then more acid gas can be adsorbed, but crystallization occurs more readily which reduces effective surface area
Solution Approach 1:
The saccharide acts as a mediator that allows higher concentrations of basic compound to be used without triggering crystallization. The complex formed between saccharide and basic compound remains stable even at high basic compound concentrations, preventing the harmful crystallization effect
3Duration of action of moving object
If the adsorbent is used for extended periods to maximize utilization, then operational efficiency improves, but the basic compound crystallizes over time which decreases adsorption performance
Solution Approach 1:
The saccharide is incorporated into the adsorbent structure in advance, creating a preliminary protective complex with the basic compound. This preliminary action prevents crystallization from occurring during extended use, thereby maintaining adsorption performance throughout the adsorbent's lifespan
Solution Approach 2:
The saccharide serves as a long-term intermediary that continuously prevents crystallization of the basic compound during extended operational periods, ensuring stable adsorption performance over time
