Three different power-to-methane process chains with grid injection in two scales (1 MW el and 6 ) were analysed regarding their investment operation cost. The based on biological or catalytic bubbling fluidised bed methanation combination proton exchange membrane solid oxide electrolyser cells. A bottom-up techno-economic analysis showed a cost benefit of around 17–19% lower biomethane product...

Co-gasification of refuse derived fuel (RDF) and wood chips was experimented in the Nong Bua dual fluidised bed steam gasifier Thailand. The effect mass RDF pellets feed (R/F ratio) investigated on performance entire process conditions product gas properties. test results showed that addition small ratio up to 30% did not affect operation conditions. concentrations H2, CO, CO2, CH4 from a binar...

Heat management problems often prevail in reactors when highly exothermic chemical reactions occur. In these situations, fluidised bed are preferred due to their excellent heat transfer capabilities. However, the design, scale-up and operation of is still challenging complex hydrodynamics. To gain a better understanding on transport reactors, degree temperature non-uniformity for several fluidi...

High temperature CO 2 and SO sequential capture in a bubbling fluidised bed was investigated using natural limestone synthetic composite pellets. Calcination conducted under oxy-combustion conditions, while carbonation sulphation occurred an air-combustion atmosphere. The goal of /SO is to desulphurise the flue gas first, followed by cyclic calcination. Here, fresh sorbent first used calcinatio...

The treatment and disposal of sewage sludge is one the most important critical issues wastewater plants. One option for liquidation production fuel in form pellets from mixed paper mill sludge. This study presents results combustion pelletized fuels, namely sludge, their 2:1 4:1 blends a fluidized bed combustor. flue gas was analysed after reaching steady state at temperatures 700–800 °C. Commo...
