| 成果简介 | NOVELTY - Present invention relates to a method of producing biofuel from sewage sludge, namely sediment of primary settling tanks and dehydrated excess active sludge in pure form or mixed in any ratio, which consists in the fact that biofuel is produced from sewage sludge during hydrothermal liquefaction in a batch reactor, It differs from known designs in that conversion is carried out using a catalyst consisting of a mineral zeolite decationised matrix impregnated with nickel and copper ions in amount of 4 and 3% of the weight of the mineral matrix, respectively, while observing the following process parameters: dry substance dose of biomass 1:15–1:5, temperature 250–280 °C, pressure is 3.5–6 MPa, catalyst dose is 10–15% of waste water sludge weight in terms of dry substance. USE - Chemistry. ADVANTAGE - Present invention increases output of biofuel when processing sewage sludge by hydrothermal liquefaction. 1 cl, 1 dwg, 2 tbl, 3 ex |
