Silver-Beta Zeolite Filtration for Alcoholic Beverage Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing unwanted components like sulfur compounds and pyridine from alcoholic beverages during storage are inefficient, leading to product loss and quality issues, as they do not effectively address the removal of specific compounds such as dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide.
Innovation Solution
A metal-supported zeolite, specifically with silver as the metal component supported on beta-type or Y-type zeolites, is used to filter alcoholic beverages, effectively removing unwanted components like dimethyl sulfide, dimethyl disulfide, and pyridine while maintaining flavor components, with a liquid-hourly space velocity of 1-30 h^-1 and a temperature range of -20 to 100 °C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional storage methods are used to mature alcoholic beverages, then the beverages develop intrinsic taste through spontaneous chemical reactions, but product loss increases due to evaporation and absorption by barrels
Solution Approach 1:
The patent applies preliminary action by proactively removing unwanted components (sulfur compounds, pyridine, etc.) from the alcoholic beverage before storage, rather than waiting for spontaneous changes during long-term storage. This pre-treatment approach eliminates harmful substances early in the process, reducing the need for extended storage periods and thereby minimizing evaporation losses and barrel absorption.
2Reliability
If storage period is prolonged to remove unwanted components naturally, then quality improves through maturation, but productivity decreases due to increased product loss
Solution Approach 1:
The patent implements preliminary action by using a metal-supported zeolite catalyst to pre-remove unwanted components (sulfur compounds, pyridine, etc.) before storage. This eliminates the need for prolonged storage periods required for natural maturation, thereby significantly reducing evaporation losses and improving production efficiency while still achieving high-quality products.
Solution Approach 2:
The patent applies parameter changes by introducing a catalyst (metal-supported zeolite) that alters the chemical environment of the alcoholic beverage. This catalytic approach enables rapid removal of unwanted components through enhanced adsorption and chemical reactions, replacing the slow natural maturation process and reducing storage time requirements.
3Loss of substance
If existing adsorbent methods are used to remove unwanted components, then some purification is achieved, but removal efficiency of specific compounds (dimethyl sulfide, pyridine) is insufficient
Solution Approach 1:
The patent applies composite materials by using a metal-supported zeolite catalyst, which combines metal particles (with catalytic activity) and zeolite (with adsorption properties). This composite structure provides both adsorption capacity for sulfur compounds and catalytic activity for converting pyridine and other nitrogen-containing compounds, achieving superior removal efficiency compared to single-material adsorbents.
Solution Approach 2:
The patent applies parameter changes by introducing a catalyst that modifies the chemical reactivity of the system. The metal-supported zeolite changes the chemical environment to enhance the removal of specific compounds through catalytic reactions, going beyond simple physical adsorption to achieve more effective purification of refractory compounds like pyridine.
