Abstract
Proximate and Ultimate analyses of biocoal briquettes were undertaken with the aim of presenting the analytical results and ascertaining the optimum biomass composition for use as composite domestic fuel. Coal samples from 2 coal mines of Ogboyaga and Okaba in Kogi state of Nigeria were collected. The samples were pulverized and blend ed with sawdust at various mixing proportions of 0:100, 10:90, 20:80, 30:70, 40:60, 50:50 and 100:0 sawdust: Coal . Cassava st arch was used as binding agent while calcium hydroxide was used as a desulphurizer for the briquettes. Briquettes of various blends were produced. Proximate and ultimate analyses were carried out to ascertain the elemental composition of the raw material s and the biocoal briquettes. Experimental tests, which involved the determination of calor ific value was also determined. This study revealed that biocoal briquettes from Okaba and Ogboyaga coal mines are suitable for the production of environmentally solid fuel that can be used for domestic heat applications. It showed further that all
