Journal ArticleDOI
Biomass gasification in a 100 kWth steam-oxygen blown circulating fluidized bed gasifier: Effects of operational conditions on product gas distribution and tar formation
TL;DR: In this paper, the effects of operational conditions (e.g., steam to biomass ratio (SBR), oxygen to biomass stoichiometric ratio (ER) and gasification temperature) and bed materials on the composition distribution of the product gas and tar formation from these fuels were investigated.
Journal ArticleDOI
Limestone and dolomite as sulfur absorbents under pressurized gasification conditions
TL;DR: In this paper, the capture of H2S by both calcined limestone and fully calcined dolomite was studied with a pressurized thermogravimetric apparatus.
Journal ArticleDOI
Surface area of calcium oxide and kinetics of calcium sulfide formation
TL;DR: In this paper, the authors evaluated the relationship between surface area and reaction rate and found that the rate of CaS formation increases exponentially with the specific surface area of CaO in micrometer size particles and that the effect of surface area on reactivity is at least as great as that expected for pure diffusion control.
Journal ArticleDOI
Hydrogen Sulfide Capture by Limestone and Dolomite at Elevated Pressure. 1. Sorbent Performance
TL;DR: In this paper, a set of physically and chemically different limestones and dolomites under pressurized conditions, typically for those in a pressurized fluidized-bed gasifier (2 MPa, 950 C), were compared with the same sorbents under combustion conditions.

The sulphidation of calcined limestone with hydrogen sulphide and carbonyl sulphide
A.B.M. Heesink,W.P.M. van Swaaij +1 more
TL;DR: In this paper, a thermogravimetric analyzer was used to study the sulphidation of calcined limestone with H2S, COS and mixtures of H 2S and COS at temperatures between 500 and 700°C.
