sunliquid®

cellulosic ethanol from agricultural residues

改訂日 :
2022年11月23日

The sunliquid® process for the sustainable and economic production of cellulosic ethanol is fully developed, being designed for industrial plants with a production capacity of 50,000 to 150,000 ton of cellulosic ethanol per year. Clariant provides the know-how and technology for all unit operations on a turnkey basis, coupled with the expertise required for successful implementation.

 

Pre-treatment
Chemical-free pre-treatment lowers production and investment costs. At the same time, environmental, health and safety risks are minimized.

Enzyme production

A small percentage of the pre-treated feedstock is used for enzyme production, which is an integrated part of the process and takes place on-site at the ethanol plant. This makes a major contribution to the economic efficiency of the overall process, resulting in a significant reduction in production costs and ensuring independence from supply shortages and price volatility.

 

Hydrolysis

A bespoke enzyme mixture hydrolyses cellulose and hemicellulose chains to form sugar monomers. This step is also termed saccharification. The enzymes are highly optimized based on feedstock and process parameters, resulting in maximum yields and short reaction times under optimal conditions.

 

Fermentation

Using optimized microorganisms, the sunliquid® process provides for efficient fermentation, giving rise to maximum ethanol yields. This highly-optimized, one-pot system simultaneously converts both C5 and C6 sugars to ethanol, delivering up to 50% more ethanol than conventional processes which convert only C6 sugars.

 

Separation

The innovative and highly energy saving purification method reduces energy demand by up to 50% compared with conventional distillation. It is based on thorough process planning and energy integration, resulting in an entirely energy self-sufficient process.
