Solution Overview
Problem
Current methods for reducing phosphorus content in liquid hydrocarbons from ethylene dimerization processes are expensive, time-consuming, and often require multi-step procedures, making it challenging to meet pipeline specification limits for blending with gasoline, which negatively impacts process economics.
Innovation Solution
A method involving contacting the liquid hydrocarbons with a catalyst comprising copper (II) oxide, zinc oxide, and aluminum oxide at room temperature and ambient pressure, effectively reducing phosphorus content by converting phosphorus-containing compounds into less soluble forms, thereby allowing for efficient blending with gasoline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If distillation and treatment with oxidizing agents are used to reduce phosphorus content, then phosphorus levels are reduced, but the process becomes expensive, time-consuming, and complex
Solution Approach 1:
The invention changes the chemical parameters by using copper (II) oxide as a catalyst under mild conditions (room temperature, ambient pressure) to convert phosphorus compounds into less soluble forms, eliminating the need for complex distillation and oxidizing agent treatment steps while achieving effective phosphorus removal
Solution Approach 2:
The invention extracts phosphorus from the liquid hydrocarbon by converting it into a less soluble form through catalytic reaction with copper (II) oxide, allowing the phosphorus to be separated from the hydrocarbon phase without requiring complex multi-step purification processes
2Manufacturing precision
If multi-step procedures are used to reduce phosphorus content, then phosphorus levels are reduced, but processing time increases
Solution Approach 1:
The invention combines multiple functions (catalysis, phosphorus conversion, and separation) into a single treatment step using copper (II) oxide, replacing the traditional multi-step sequence of distillation and oxidizing agent treatment, thereby significantly reducing processing time while maintaining effective phosphorus removal
3Manufacturing precision
If high temperature procedures are used to reduce phosphorus content, then phosphorus levels are reduced, but energy consumption increases
Solution Approach 1:
The invention changes the thermal parameters by conducting the phosphorus removal reaction at room temperature using copper (II) oxide as a catalyst, eliminating the need for high temperature heating and thereby significantly reducing energy consumption while achieving effective phosphorus conversion and removal
