摘要

Finite petroleum reserves and stringent environmental regulations stimulate the development of alternative fuels that are economically viable and clean.The diesel fuel (C10-20 hydrocarbons) derived from syngas by Fischer-Tropsch synthesis (FTS) is a promising choice,as it has the merits of low sulfur and aromatic contents,reduced NOx and particulate emissions,and high cetane number.However,the Anderson-Schulz-Flory (ASF) distribution imposes severe limitation on the selectivity towards diesel of only 39％ over conventional FTS catalysts.Efforts to break the limitation by incorporating acid sites into the FTS catalysts are proven to be less successful,for acid-catalyzed cracking is usually not able to restrain the products precisely at the C10-20 range.
