Acid-modified phonolite and Foamed zeolite as supports for NiW catalysts for deoxygenation of waste rendering fat

Popis výsledku v původním jazyce

Acid-modified phonolite material (synthesized according to [1]), Al2O3/foam zeolite and foam zeolite were used as catalyst supports for NiW catalysts with various Ni/W weight ratios. The zeolite type materials were prepared by a novel procedure from natural clinoptilolite. Phonolite materials were loaded with 15 °wt. % of NiW phase with Ni:W ratios 0.5, 1.0 and 2.0. Al2O3/foam zeolite was loaded with 35 wt. % of NiW with Ni:W = 0.30 and pure foamed zeolite was loaded with 43 wt.% of NiW phase with Ni:W = 0.30. Catalysts properties were compared in deoxygenation of rendering fat into hydrocarbons. A reference NiW/Al2O3 catalyst (32 % NiW, Ni:W = 0,28) was used for comparison of catalytic properties of synthesized materials. Catalytic tests were carried out in an autoclave pressurized at 7 MPa (H2) at room temperature. Then, it was hermetically closed and heated to 365 °C for 1 h under vigorous stirring. Catalysts were characterized by N2 physisorption, XRD and XRF. Waste animal rendering fat was used as feedstock. The liquid products were analysed by simulated distillation, C, H, N, S elemental analysis, ATR and density (15 °C). Gaseous product was characterized by RGA-GC. Thus, the yields to different products such as free fatty acids or hydrocarbons were obtained. Phonolite modified solids were tested the first time as catalysts and compared to clasical NiW/Al2O3 and novel NiW/foam zeolite type materials.
