In the present study, safflower biodiesel (safflower oil methyl ester) was produced through transesterification. Biodiesel fuel obtained from safflower was blended with diesel fuel in ratios of 2% (B2) and 20% (B20). Kinematic viscosity, density, water content, heating value, flash point, clouding point, pour point, ash content, copper strip corrosion and CFPP (cold filter plug point) tests were performed on B2, B20, B100 fuel blends and diesel fuel. A four stroke, single cylinder, water cooled diesel engine with a direct injection fuel system was operated with B2, B20, B100 and diesel fuels at partial load for 100 hours and samples were taken from the engine lubricating oil at certain hours. The wear elements iron, aluminum, lead, copper and chromium contents of the samples taken from the engine lubricating oil were examined.

Fe/HNT(Iron/Halloysite-nanotube) heterogeneous semiconductor catalysts operating effectively under visible light were developed by using FeCl3, FeSO4and Fe(OH)3sludge precipitated after electro-Fenton process and named as Fe/HNT-I, Fe/HNT-II and Fe/HNT-III, respectively. Chemical configuration and particle morphology of the catalysts were characterized with XRD, SEM-EDS and UV–vis DRS. Effect of the developed Fe/HNT photocatalysts was investigated for the degradation of Reactive Orange 16(RO16) textile dye under visible light. The photocatalytic decolorization of RO16 was 95.6%, 99.3% and 96.6%, respectively. It was found that the photocatalytic performance of Fe/HNT-III catalyst under visible light was effective compared to Fe/HNT-I and Fe/HNTII. The iron ratio in the catalyst’s structure(Fe:HNT ratio 0.25, 0.5 and 0.75(w/w)) and p H value(4, 7 and 9) in production phase were also changed to investigate the photocatalytic effect of Fe/HNT-III. An Fe:HNT ratio of 0.25 and a p H of 4 were determined as the optimum conditions for catalyst production. Optimum H2O2dosage value was also investigated for photocatalytic oxidation process and determined to be 10 m M. Finally, the optimum conditions were further used for the degradation of Terbinafine hydrochloride(Ter HCl) active drug and the treatment of wastewater from the textile and pharmaceutical industries.
