Title: **Innovative Contributions of Tian Ruan in Isobutanol Production**

Introduction

Tian Ruan, an accomplished inventor based in Katy, TX, holds three patents that contribute significantly to the field of chemical engineering, particularly in the production of isobutanol. His innovative processes offer practical solutions for converting ethanol and syngas into valuable alcohols, showcasing his expertise in catalysis and synthesis.

Latest Patents

Ruan's latest patents focus on processes for isobutanol production from ethanol and syngas. The first patent details a method where syngas and ethanol react in the presence of a first heterogeneous catalyst within a reaction zone. This process generates a first reactor effluent that contains a mixture of alcohols. In the second reaction zone, another heterogeneous catalyst initiates further reactions to refine the product into a second reactor effluent. This effluent is then separated into an overhead gas stream and a liquid bottom stream, which is further divided into C1-2, C3, and C4+ streams, facilitating the recovery of isobutanol from the C4+ fraction.

The second patent offers an improved synthesis process for isobutanol via synthesis gas. This two-step methodology circumvents the slower alpha-carbon addition reaction seen in conventional one-step methods. In the first reaction zone, ethanol and propanol are produced, which can then interact with methanol or syngas in the second zone. This technique utilizes catalytic processes to facilitate faster beta-carbon addition reactions, leading to enhanced isobutanol productivity.
