| Research Abstract |
The tests of heavy oil sorption by the peat mixed with water indicated that the peat is capable of retaining A-type and C-type heavy oil as much as 4 to 5 times and about 6.5 times the peat, respectively. The cylindrical column tests indicated that the peat soaks upkerosene to a higher position in an oil absorption process and retains kerosene at a higher position in an oil desorption process compared with other oil absorbents. The A-type and C-type heavy oil in the peat was biodegraded by 70% and 30% under 25℃for 70 days, respectively.
