Abstract

Promotion of Coconut Shell Gasification by Steam Reforming on Nickel-Dolomite

Highlights

  • Gasification of biomass is a potential source of renewable energy to produce useful gases such as syn gas or pure hydrogen

  • At the start up of experimental run, the reactor was charged with 10 g Ni/dolomite catalyst as bed material and temperature in the catalytic bed was measured by thermocouple type K

  • Effect of catalyst: The influence of catalytic gasification on product gas compositions by using Nickel-dolomite catalyst operated at temperature 800°C, steam to carbon ratio (S/C) 0.95 and biomass feed rate 0.5 g min−1

Summary

Introduction

Gasification of biomass is a potential source of renewable energy to produce useful gases such as syn gas or pure hydrogen. The catalytic gasification process is an attractive technological alternative to deal with tar and to produce high yield of syn gas. Nickel and dolomite catalysts have been proven to be very active in terms of tar reduction and it shows excellent catalytic activity, resistance of coking and sulfur poisoning[2,9,10]. In this experiment, investigations were carried out to determine the efficiency of steam reforming nickel catalyst support on dolomite in a fluidized bed gasifier and to study the effects of some operating parameters on product gas compositions
