Effect of the hydrogen to feedstock ratio on the hydrotreating of the mixture of petroleum middle distillates and rape-seed oil
Original language description
The hydrotreating of vegetable oils and animal fats is a possible way to produce a high-quality renew-able diesel fuel component. It can be produced by processing the bio-raw material in new units or by the co-processing of the renewable raw material together with the petroleum middle distillates in existing hy-drotreating units. This work was focused on investigating the effect of the hydrogen to the feedstock ratio on the hydrotreating of a mixture of petroleum middle distillates and rapeseed oil in a weight ratio of 8:2 in a tubular fixed bed reactor. The hydrotreating was performed using a sulfided Ni-Mo/Al2O3 catalyst, a tem-perature of 345 °C, a WHSV of 1.0 h 1, a pressure of 4.0 MPa and a hydrogen to the feedstock ratio in the range of 120 600 m3∙m-3. The hydrogen to feedstock ratio of 120 m3∙m-3 was not sufficient to desulfurise the feedstock to the level of 10 mg∙kg 1. On the contrary, increasing the hydrogen to feedstock ratio to above 240 m3∙m 3 had no significant effect on the yield and quality of the obtained products. Therefore, the ratio of 240 m3∙m-3 was considered as sufficient for the hydrotreating of the mixture of the petroleum middle distil-lates and rapeseed oil.
