Reactor and Process for Maximizing Methanol Yield Through the Use of Catalyst Layers

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a reactor and process for catalytic methanol production using multiple catalyst layers arranged within the reactor. The design places a highly active catalyst layer at the upstream (entry) side, followed by one or more downstream layers with lower, and then increasing, activities. This arrangement optimizes heat management within the reactor and maximizes the yield of methanol from synthesis gas (a mixture of hydrogen and carbon oxides), by ensuring high initial conversion, controlling hotspots, reducing catalyst deactivation, and improving efficiency.

Use CasesContent extracted from patent full text and abstract with AI.

• Industrial methanol production plants aiming to increase efficiency and output.
• Chemical plants seeking to upgrade or retrofit existing methanol reactors for higher yields and reduced operational costs.
• Gas-to-liquids processes converting natural gas or biogas into methanol.
• Facilities that require stable, long-term methanol production with lower maintenance downtime.
• Integration into modular or compact reactor designs where space and efficiency are critical.

BenefitsContent extracted from patent full text and abstract with AI.

• Maximizes methanol yield per pass through the reactor, increasing overall plant productivity.
• Reduces catalyst deactivation and maintenance costs by controlling reactor temperatures and heat hotspots.
• Allows for extended catalyst life, reducing the need for frequent replacement and lowering waste.
• Improves energy efficiency by optimizing heat management within the reactor, possibly enabling energy recovery (e.g., by using reactor cooling water for steam generation).
• Facilitates flexible reactor operation, including easier upgrades with varied catalyst materials or used catalysts.
• Enables higher conversion rates of both carbon monoxide and carbon dioxide, enhancing resource utilization and potentially lowering emissions.

Patent Abstract

The invention relates to a reactor for the catalytic production of methanol, in which at least two catalyst layers are arranged. The first catalyst layer is arranged upstream and the second catalyst layer is arranged downstream. The activity of the first catalyst layer is higher than the activity of the second catalyst layer.
