    [20] [20] > In a further embodiment, the lipid material provided in step a) comprises about 30 to about 2000 N mg/kg phosphorous, preferably about 30 to about 1000 mg/kg phosphorous, more preferably D about 50 mg/kg to about 600 mg/kg phosphorous.
    [20] [20] o BRIEF DESCRIPTION OF THE DRAWINGS
    [20] [20] > As the test material passes through the pipe, the temperature of the test material increases to the N temperature level of the heated rod. As the test material starts to cause fouling on the surface of e the heated rod, the temperature difference between the rod, whose temperature is kept constant, E and the test materialout of the pipe, increases. The higher the temperature difference between the rod and the test material, the higher the fouling tendency. 3 In the experiment, the original lipid material was animal fat from Europe. The lipid material was not & subject to any pretreatment. The lipid material was used in the fouling tests as is, and also after lab- scale heat treatment. The heat treatment was performed in 1L Parr-reactor by heating the lipid material to 280 °C and keeping the lipid material at that temperature for a time of 60 min. Thepressure was not controlled during the batch heat treatment and the pressure was let to rise. After the heat treatment, two samples were created: heat treated material as is (containing solids created during the heat treatment) and heat treated material after filtration (2 um). The test matrix is presented in Table 1. Table 1. Test matrix of the fouling experiment set.
