“…Those results consistent with the previous study on copyrolysis of legume straw and lignite in a drop tube reactor from 500 to 700 ˚C. There was a trend towards linear product distributions at higher temperatures [5]. At the higher blending ratio, hydrogen availability during pyrolysis is much greater.…”

“…The largest degree of synergetic effects on the products yields was observed under 600 ˚C and the blending ratio of 73 wt.% in the co-pyrolysis of LS/DY. It can be concluded that both the higher blending ratio (around 70 wt.%) and the relatively lower temperature (around 600 ˚C) are the best conditions during the copyrolysis of biomass and coal on free fall reactor [5], [7].…”

The utilization of Indonesia low rank coal should be maximized, since the source of Indonesia law rank coals were abundant. Pyrolysis of this coal can produce liquid product which can be utilized as fuel and chemical feedstocks. The yield of liquid product is still low due to lower of comparison H/C. Since coal is non-renewable source, an effort of coal saving and to mitigate the production of greenhouse gases, biomass such as oil palm empty fruit bunch (EFB) would added as co-feeding. EFB could act as hydrogen donor in co-pyrolysis to increase liquid product. Co-pyrolysis of Indonesia low rank coal and EFB were studied in a drop tube reactor under the certain temperature (T= 500 ˚C) and time (t= 1 h) used N2 as purge gas. The effect of blending ratios of coal/EFB (100/0, 75/25, 50/50, 25/75 and 0/100%, w/w %) on the yield and composition of liquid product were studied systematically. The results showed that the higher blending ratio, the yield of liquid product and gas obtained increased, while the char decreased. The highest yield of liquid product (28,62 %) was obtained used blending ratio of coal/EFB = 25/75, w/w%. Tar composition obtained in this ratio is phenol, polycyclic aromatic hydrocarbons, alkanes, acids, esters.

To improve the yield and quality of coal pyrolysis tar while using pyrolysis gas (PG), a Ni/MgO catalyst was introduced to catalyze the pyrolysis of bituminous coal under a PG atmosphere. The effects of pyrolysis temperature, gas flow rate, catalyst packing methods, and atmosphere composition on coal pyrolysis were investigated. The yield and quality of tar obtained from Shihezi (SHZ) bituminous coal pyrolysis under N 2 , PG, and PG over a Ni/MgO catalyst were found to vary with the increase of pyrolysis temperature. The catalyst packed in the upper layer results in higher tar yields, but mixing the catalyst and coal leads to an increase in the maltene yield. The components in PG improved the tar yield and tar quality. Finally, a higher tar yield can be obtained from SHZ coal pyrolysis under CO/H 2 , CO 2 /H 2 , and CO 2 /CH 4 atmospheres using a Ni/MgO catalyst.
