Gasification of tri-fuel blends to syngas production

This study is conducted to utilize the various types of fuel such as coal, biomass and refinery residue to produce a synthetic natural gas (syngas) which is a mixture of carbon monoxide and hydrogen-rich gas. The gasification behavior of blended triple fuels was conducted using Bubbling Atmospheric Fluidized Bed Gasifier (BFBG) at TNB Research Sdn Bhd. The three fuels were also characterized using calorific value determination, proximate analysis (moisture, volatile matter, fixed carbon, and ash) and ultimate analysis (carbon, hydrogen, nitrogen and sulfur). The gasification tests using BFBG were conducted at constant equivalence ratio (ER) of 0.3, bed height of 150mm and air as the gasifying agent. H
