“…Olivine has been investigated by several groups, with studies being carried out on non-calcined, calcined, and doped material [3,10,[22][23][24], and it is known that olivine needs to undergo activation to produce the catalytic effects on tar species in the raw gas. The changes in activity of olivine is commonly attributed to Fe migration in the particle, which has been shown to be a result of calcination [3], and to the CaO layer that is formed during the interaction with biomass ash [20,21,25,26].…”

“…Wang et al [214] studied the catalytic performance of Co/Mg/ Al catalysts in the steam reforming of biomass and found that the Co/Mg/Al (10/40/50) catalyst exhibited much higher activity and resistance to coke deposition than Co/α-Al 2 O 3 , Co/Al, Co/Mg, and Ni/Mg/Al (9/66/25) catalysts. Moreover, Fredriksson et al [215] studied the stability of Austrian olivine as tar removal catalyst. After exposure to oxidizing gases, the free Fe phases were identified: Fe 2 O 3 and Fe 3 O 4 or MgFe 2 O 4 .…”

The biomass thermochemical conversion process includes two major approaches: pyrolysis and gasification. The advantages of pyrolysis and gasification of biomass feedstock in the presence of various catalyst systems are critically reviewed. The role of a catalyst in pyrolysis of biomass and its major components cellulose, hemicellulose and lignin is investigated. The discussion is focused on elucidating the reaction mechanisms involved in the formation of aromatics and phenols during catalytic pyrolysis. The pyrolysis performance of two major catalyst systems, metal-containing catalysts and zeolite catalysts, is analyzed. The impact of the catalyst on the deoxygenation efficiency is ascertained. In the catalytic gasification process, two major catalyst systems including alkali metals and noble metal catalysts are employed. This review illustrates the function of the catalyst in improving the yields of syngas and hydrogen and the mechanistic aspects of the reduction of tar and char formed during gasification. Ultimately, the review is intended to introduce the state of art in the biomass thermochemical conversion with an emphasis on the importance of the catalyst in producing value-added products.

“…Therefore, many studies have been conducted to decompose tar into fuel gas. Researchers are using various minerals as catalysts in this decomposition process such as olivine, [10][11][12][13] clay minerals, 14,15) and iron ores. [16][17][18] Scrutinizing the properties of each biomass pyrolysis product, it is highly likely that bio-char can be used as a catalyst for decomposition of bio-tar, and which will increase the efficiency of biomass utilization.…”

This paper presents a technology to utilize bio-char and bio-tar from the pyrolysis of oil palm empty fruit bunch, EFB. In this study, tar vapor from pyrolysis of EFB was infiltrated within porous bio-char and carbon deposition occurred on the pore surface by chemical vapor infiltration process. For preparation, EFB particles were made into pellets. In the first part of experiments, porous bio-char pellets were produced by slowly heating the EFB pellets in a tube furnace in argon atmosphere to terminal temperatures of 500-800°C. In the second part, the porous bio-char pellets were used as precursor for tar decomposition process to deposit carbon within the bio-char pores. Tar vapor was obtained from the pyrolysis of EFB at 400-500°C at a fast heating rate for tar decomposition to occur. The purpose of this research is to investigate the amount of carbon deposited within bio-char by this tar carbonization process as compared to carbon contents of metallurgical coke. We showed how EFB bio-char was used as the tar filter and in the process to produce carbon-infiltrated bio-char, a useful renewable energy source for ironmaking process.
