Abstract In order to explore the feasibility of using semi-coke to prepare tea baked briquette, Xinjiang semi-coke and fruit charcoal were used to prepare the tea baked briquette based semi-coke. And the forming process parameters of the briquett were explored. The result revealed that with the increase of the forming pressure, forming water, binder addition ratio and residual water after drying, the filling density between the carbon particles and strength of the briquette became larger. And more compact. However, the high molding pressure would lead to the increase of the number of cracks on the briquette surface. And the carbon particle distance and the bonding property was larger and worse. When the forming pressure, forming water, binder addition ratio and residual water after drying were 25MPa, 28%, 5% and 7.5% respectively. The cold compressure strength of tea baked briquette based semi-coke reached 533N/unit. The calorific value of briquette was 28.47 MJ/Kg. And the volatile content was less than 14%, which was better than that of fruit carbon fuel. So it was reasonable to speculate that it could replace fruit carbon for baked tea.
