Polycarboxylic Acid Hydrogenation Catalyst for Low-Pressure Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogenation processes for polycarboxylic acids or derivatives require high pressures, leading to expensive equipment and fabrication costs, necessitating a more cost-effective process that can operate at lower pressures while maintaining high hydrogenation yields.
Innovation Solution
A hydrogenation process using a catalyst comprising an active metal and a support, where the support includes a Group IIA element and a Group IIIA element, and the active metal is a Group VIIIB element, operating at normal or lower pressures (1-50 Bar) to achieve high hydrogenation yields exceeding 99%.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional hydrogenation processes are used to achieve high hydrogenation yield, then hydrogenation yield exceeds 90%, but high pressure (50-200 Bar) is required leading to expensive equipment and fabrication costs
Solution Approach 1:
The patent changes the pressure parameter from conventional high pressure (50-200 Bar) to low pressure (1-10 Bar) by developing a novel catalyst system. This parameter change allows the hydrogenation process to achieve high yields without requiring expensive high-pressure equipment, directly resolving the contradiction between productivity and manufacturing cost
Solution Approach 2:
The patent employs a composite catalyst consisting of a support material (alumina, silica, or titania) combined with specific metal components (nickel, cobalt, or iron). This composite structure enhances catalytic activity and selectivity, enabling high hydrogenation yields at low pressures, thus resolving the contradiction between productivity and ease of manufacture
2Productivity
If high pressure (50-200 Bar) is applied to increase hydrogenation yield, then hydrogenation yield exceeds 90%, but equipment costs become expensive
Solution Approach 1:
The patent fundamentally changes the pressure parameter from high (50-200 Bar) to low (1-10 Bar) through the development of an optimized catalyst system. This parameter change eliminates the need for complex high-pressure equipment while maintaining high hydrogenation yields, directly addressing the contradiction between productivity and device complexity
Solution Approach 2:
The patent uses inexpensive, readily available catalyst materials (nickel, cobalt, or iron on common supports) that can operate effectively at low pressures. This approach replaces expensive, complex high-pressure equipment with simpler, cheaper catalyst-based systems, resolving the contradiction between productivity and device complexity
