MTO and MTP

For anyone working in the chemical industry, the terms MTO (Methanol-to-Olefins) and MTP (Methanol-to-Propylene) are becoming more common. At Shandong Dengzhuo, we often get questions about the difference between these two processes and which catalyst is the right fit. Let's break down the basics.

The Core Difference: What You're Making

Both processes start with methanol but aim for different key products.

• MTO is designed to produce a mix of ethylene and propylene. It's a flexible process when you need both of these fundamental building blocks.

• MTP is more specialized, tuned to maximize the production of propylene specifically.

Why the Catalyst is Key

The different outcomes are driven by the catalyst at the heart of the reaction.

• MTO processes most commonly rely on SAPO-34 catalysts. Their microporous structure is excellent for creating ethylene and propylene.

• MTP processes typically use a modified ZSM-5 catalyst. Its structure and acidity are optimized to favor propylene molecules.

Making the Right Choice for Your Needs

So, how do you choose?

• If  your operation or your customers require a balanced output of both ethylene and propylene, then the MTO pathway is the way to go.

• If  there's a specific, high demand for propylene in your market, then focusing on MTP technology will be more efficient.
