Effect of Fe₂O₃ on steam gasification of subbituminous coal/woody biomass mixture

Abstract

This study investigated the steam gasification of Indonesian Adaro coal and Japanese cedar mixed in a 1:1 ratio with the physical addition of 10 wt% Fe 2 O 3 in 50 vol% H 2 O at ambient atmospheric pressure and 800°C for 1 h. The primary objective of this work was to examine the effectiveness of an iron catalyst on the interaction between Indonesian Adaro coal and Japanese cedar. The study demonstrated that the H 2 evolution amount for co-gasification of Japanese cedar and Adaro coal (with 1:1 ratio in weight) without a Fe catalyst was 100 mmol/g-char. However, the H 2 evolution amount for co-gasification with the addition of Fe 2 O 3 was 152 mmol/g-char. The increase in the cogasification for H 2 evolution was based on a change in the char structure during pyrolysis and gasification. 282

Kinetics and Physicochemical Morphology Evolution of Low and High-Ash Pyrolytic Tire Char during CO2 Gasification

“…The active ash of tire char can further be divided into two classes. One class is known to reduce the gasification reaction activation energy, and AAEM and Fe 38 are typical examples. This class is referred to as catalytic ash in this work.…”

Experimental study of the catalytic effect of iron on low-rank coal gasification

“…The process of low-rank coal gasification with carbon dioxide or steam at high temperatures produced gaseous products of hydrogen and carbon oxides, a small amount of methane, and other light hydrocarbons. Gaseous products can be used in the system of Integrated Gasification Combined Cycle (IGCC), chemical synthesis, fuel cells, and fuel 4,5 .Catalytic gasification in the coal conversion process is a promising way to develop significantly higher efficient coal conversion technology than non-catalytic gasification [6][7][8] . Using a catalyst in the process of coal gasification can decrease the required size of the reactor and enhance the reaction rate of coal and gasification agents.…”
