A comparison of catalysts zeolite and calcined dolomite for gas production from pyrolysis of municipal solid waste (MSW)

Catalytic Energy Production from Municipal Solid Waste Biomass: Case Study in Perlis-Malaysia

“…The use of dolomite for biomass gasification in fluidized bed is attractive since it is a cheap material and exhibits proven catalytic activity and effectiveness to reduce tars both in laboratory-scale gasifiers and pilot plants [8]. Dolomite is more effective than zeolite as catalyst although is less resistant against attrition and generates more particulates in the product gas [9,10]. Calcined dolomite has shown even better efficiency for increasing hydrogen content as compared to raw dolomite [11].…”

“…The loss in weight during the measurement was recorded continuously, and the results were presented as a function of temperature. The tar formed during gasification is one of the challenging issues, catalytic gasification for tar reduction has been promising [11,27,28]. Since a few decades, the use of catalyst in biomass gasification had attracted much attention.…”

“…The moisture content is measured and determined with the amount of water lost from selected materials upon drying to a constant weight. It is directly affected by physical and chemical properties of material which enable it to absorb the outlet water in the environment [11]. Fixed carbon is the carbon remaining on surface as charcoal.…”

“…Among these processes, biomass gasification and pyrolysis technologies have attracted the considerable attention from both industrial and academic researchers due to its high conversion efficiency [7,11]. However, the gasification process is considered as a self-sufficient autothermic technological process in terms of an energy balance.…”

“…Proximate analysis was investigated according to European PN-EN/PN-ISO and ASTM standards for determination of moisture (PN-EN 14774-3:2010; ASTM E-871) [8,23,24], volatile matter (PN-EN 15148:2010.900) [8,11,[24][25][26], fixed carbon and ash (PN-EN14775:2010), as well as determination of gross calorific value/high heating value (PN-EN 14918:2010 and PN-ISO 1928) [8,24] in biomass sample.…”
