High Carbon Alcohol Adsorption & Separation Technology

This technology is specifically developed for the high-value utilization of high carbon alcohols in hydrocarbon streams. It adopts a simulated moving bed (SMB) adsorption process and is equipped with proprietary adsorbents, significantly enhancing the value of high carbon alcohol-rich oil fractions.

Key Features & Benefits

Broad Feedstock Compatibility

This process is suitable for high-carbon, alcohol-rich oil products that undergo varying distillation stages, such as Fischer-Tropsch synthetic oil. The carbon and alcohol content of the raw materials can be adjusted between 2% and 80%.

Efficient Purification of Oxygenates

The purified products achieve high purity levels (greater than 97%), offering substantial added value.

Case Study

A company currently operates a 150,000 tons/year Fischer-Tropsch (FT) synthesis unit, with an annual output of 100,000 tons of FT synthetic oil. The FT oil contains a high proportion of oxygenates—over 50%—which significantly impacts downstream utilization. To address this, the company intends to adopt a separation process to isolate oxygenates and obtain high-value high carbon alcohol products.

The previously planned extraction-based separation approach was limited by excessive energy consumption. Therefore, an urgent need arose to optimize the production process, enabling high-value utilization of oxygen elements and ensuring an affordable and abundant feedstock supply for the fine chemicals industry, thereby promoting high-quality industrial development.

Solution：

The High Carbon Alcohol Separation Technology is applied to process the C5–C8 and C9–C14 distillation fractions of FT oil, producing high-purity C2–C11 alcohols.
