In this research, the continuously operated laboratory scale Kaldnes (k1) moving bed biofilm reactors (MBBRs) under partial nitrification-denitrification process were used for treatment of synthetic wastewater containing ammonium and glucose. The Anoxic and Aerobic reactors were filled to 40 and 50 %( v/v) to attach and retain biomass with k1 biofilm carriers, respectively. The favorite interna...

The choice of appropriate reactors and reforming strategies is key to make progresses on scaling up H2 production processes from raw bio-oil. This work compares the performance (conversion, product yields deactivation) packed-bed fluidized-bed (PBR FBR, respectively) using a NiAl2O4 spinel derived catalyst for bio-oil via steam (SR) sorption enhanced SR (SESR, with dolomite capture CO2). experi...

For aquaculture wastewater with low ammonium nitrogen concentration, combining the carrier adsorption and biological removal processes can maximize their respective advantages. Functional ceramsite that has excellent performance biocompatibility was key to moving bed biofilm reactor (MBBR) adsorption—shortcut simultaneous nitrification denitrification (shortcut SND) process. Our group prepared ...

Fractions of waste square timber and waste ordinary plywood were pyrolyzed in a pyrolysis plant equipped with a fluidized bed reactor and a dual char separation system. The maximum bio-oil yield of about 65 wt.% was obtained at reaction temperatures of 450-500 °C for both feed materials. For quantitative analysis of bio-oil, the relative response factor (RRF) of each component was calculated us...

In a novel dual bed reactor Fischer-Tropsch synthesis was studied by using two diffrent cobalt catalysts. An alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a Rutenuim promoted cobalt catalyst in the second bed. The activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed r...
