The invention provides an upgrading process of briquette coal raw material coated with low-order coal and a particulate matter, wherein the upgrading process includes steps of pelletizing the mixture of a biomass and the garbage, and then mixing with low-order coal and organic bonding agent, and forming a low-order coal main body raw material; pressurizing the non-low-order coal and forming a non-low-order coal briquette coal bed layer; adding the low-order coal main body raw material and the non-low-order coal in the non-low-order coal briquette coal bed layer, and making the non-low-order coal stay at the periphery of the low-order coal main body raw material; continuing to pressurize and form a briquette coal medium layer; adding the non-low-order coal in the briquette coal medium layer, pressurizing and acquiring the briquette coal raw material; upgrading the briquette coal raw material, and acquiring raw gas, oil tar, crude benzene, and coke. The upgrading process can solve the problem of limited application of the low-order coal, the biomass and the garbage in the absence of a large-scale industrial device in the prior art, and effectively overcomes the problem of low utilization rate of the existed tamping coke oven and surplus output of the coking industry; thus the upgrading process has considerate economic benefit and a certain social benefit.
