This article presents the experiments on hydroconversion of mixtures safflower oil (SO) mixed with straight run gas (SRGO) in a different ratio as an alternative to obtain biojet. The research was conducted two stages; first stage mixture SO/SRGO subjected hydrotreating at 350 °C, 380 80 bar, LHSV 1 h−1 and 1.5 h−1, over sulfided NiMo/Al2O3 catalyst, while second which already hydrotreated hydr...

evaluation of pre-fixed biological tissues preparation methods for atr-ftir biospectroscopy fourier transform infrared (ftir) spectroscopy in atr (attenuated total reflection) mode is a powerful tool for studying biomedical samples, which can provide important structural information on the molecular composition. currently, formalin fixation and paraffin preservation (ffpp) is the preferred source ...

Hierarchical AlSBA-15–zeolite materials were utilized as a supports for preparing hydroisomerization catalysts. Detailed consideration was given to: (i) the effect of zeolite type introduced into composites (where is ?, mordenite or ZSM-5) well (ii) promotion Pd addition. The showed higher activity in isomerization compared to Pt/AlSBA-15. enhanced efficiency explained by appropriate metallic a...

Abstract The Investment Casting (IC) process is a type of casting that can produce the suitable shape and size components by minimizing porosity defects. However, research on ICs for manufacture artificial hip joints made from Ti6Al4V still lacking. Therefore, purpose this study to determine mechanical properties an joint casted using investment method. stages used in are wax injection, ejectio...
