Low‐Temperature Mineralization of Crude Oil in Soil
Abstract Prudhoe Bay crude oil was added at 0,3, and 6% wt oil to wt of soil in a laboratory study designed to evaluate methods of enhancing crude oil mineralization at 10°C. Both mechanical stirring of the soil and fertilization were effective in enhancing mineralization. Under the most favorable c...
