摘要:
Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are directly produced from synthesis gas over activated carbon supported cobalt based Fischer-Tropsch catalyst under the condition of temperature within the range of 120 to 400null C., reaction pressure within the range of 0.5 to 10.0 MPa, volume hourly space velocity of a mixture of hydrogen and carbon monoxide within the range of 100 to 5000, the mole ratio of hydrogen to carbon monoxide within the range of 1 to 4. Diesel fuels containing at least 95 wt % paraffins with an iso to normal ratio of about 0.03 to 0.3,
