减少对

化石燃料的依赖,并促进本地的生物燃料生产

面临着气候变化和化石燃料储量下降的问题,我们需要寻找环保替代新能源。汽车细分市场消耗了全球大约 50% 的原油产量。借助 sunliquid®,科莱恩开发出了一个流程来生产纤维素乙醇,它是一种第二代生物燃料,因具有一流的环保性而著称。

Challenge

A WELL-KNOWN DILEMMA FOR ALTERNATIVE ENERGY: GROWING CROPS FOR FOOD OR FOR FUEL?

Already existing biofuels have been produced from canola, corn or cereals – edible plants, rising the discussion concerning food or fuel resp. competition for arable land. ­To-date the manufacture of biofuels from non-edible biomass such as straw has been very costly due to expensive enzymes needed and energy-intensive processes.

    • Sunliquid®

      The sunliquid® process for the sustainable and economic production of cellulosic ethanol is now 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. For more details see our Innovation Spotlight video . 更多
