提到玉米提取乙醇,E10什么时候,blend
参考：Some worry that production will ultimately outstrip the capacity to blend ethanol into E10.(By definition,ethanol cannot exceed 10 percent of the gasoline pool if it is blended exclusively into E10.) This limit to the use of ethanol (basically,where ethanol supply exceeds demand) is referred to as a “blend wall.”

答案

混合墙,相当于酒精混合比限制或容限.
