AI Technical Summary

Technical Problem

The existing technology has not established a complete production system for the joint preparation of hydrogen, methanol and dimethyl ether from methane, resulting in high costs for power generation and fuel use for large marine transport vehicles.

Method used

A system for the combined production of hydrogen, methanol, and dimethyl ether from methane was designed, including a methane reforming module for hydrogen production, a methanol production module, a dimethyl ether production module, and a hydrogen power generation module. Through a series of devices and fluid conduction, the system achieves the efficient conversion of methane into hydrogen, methanol, and dimethyl ether.

Benefits of technology

It reduces the cost of power generation and fuel use for large marine transport vehicles, and provides production systems for hydrogen power generation, methanol and dimethyl ether. Hydrogen can be used for power generation, and dimethyl ether is used as a new type of clean fuel to replace liquefied petroleum gas and coal gas.
