COMPARISON OF SULFIDIC AND NON-SULFIDIC CATALYSTS FOR PYROLYSIS BIO-OIL HYDROTREATING

Popis výsledku v původním jazyce

By the European Union directive RED II1 , establishing a policy to produce energy from renewable sources, EU countries should fulfil up to 20 % of their total energy to the year 2020 by biofuels. One of the opportunities to gain this requirement is to use ablative pyrolysis to produce liquid bio-oil from wheat and barley straw. Bio-oil cannot be used directly as a fuel, due it&apos;s high acidity, low stability and high water content, and has to be upgraded. One of the technologies, which provides good quality products, is a catalytic hydrotreatment. The aims of this work are (i) describe the hydrotreatment process over the sulphided NiMo/Al2O3 and non-sulphided Ni/Al2O3, Pd/Al2O3 and Co/Al2O3 catalysts and (ii) characterisation of the bio-oil and upgraded products composition and physicochemical properties. For the upgrading, a continuous flow reactor with a fixed bed of a catalyst layer was used. Hydrotreatment of the bio-oil was performed under the following reaction conditions: temperature 280-320 °C, pressure 4 MPa, WHSV 1 h-1 , hydrogen flow 90 Nl∙h- 1. Obtained products were already phase separated into organic and aqueous phases in the sampling bottles. Elemental composition and physical-chemical propertiessuch as density, kinematic viscosity, Micro Conradson residue, water content, Total and Carboxylic acid numbers were determined for the organic phase. For the fraction composition, Simulated Distillation has been used. Analysis of off-gases was performed by GC-FID/TCD.
