Phalen seam coal

SOME PROPERTIES OF OXIDIZED PHALEN SEAM COAL... 

Carbonization of the oxidized Phalen Seam coal at 550°C resulted in a non-agglomerated char. Dilatation and FSI results for this coal are given in Table II and confirm its non-coking character. The semi-coke obtained from dilatation experiments had an isotropic structure, as shown in Figure 1. 

The effect of reactor temperature and hydrogen pressure on the weight yield of solid residue recovered subsequent to hydrogenation of the oxidized Phalen Seam coal is shown in Figure 4. 

Oxidized Phalen Seam coal hydrogenated at 450°C for 3 hours at different hydrogen pressures gave the dilatation results presented in Table III. Optical micrographs of the semi-cokes obtained from dilatation experiments are shown in Figures 5 to 8.

The oxygen content of the solid residue recovered from hydrogenation experiments of Phalen Seam coal at various hydrogen pressures are given in Table IV. The oxygen content was found to decrease from 6.63% for coal samples hydrogenated at 1.5 MPa to 2.54% for coal samples hydrogenated at 13.9 MPa.

An oxidized bituminous coal from Phalen Seam in Nova Scotia was obtained from the Cape Breton Development Corporation. Some properties of this coal are given in Table I. Hydrogenation was carried out in a stainless steel, vertical fixed bed reactor of 155 ml capacity Q). Approximately 150 g of sample, -4 to 8 US...
