Abstract

The invention provides an upgrading process of forming materials containing low-order coal, biomass and rubbish. The upgrading process includes: evenly mixing and then pressing the low-order coal, biomass powder and rubbish powder into particles; mixing the particles with an assistant to form a mixture subjected to extrusion forming to obtain the forming materials; subjecting the forming materials to upgrading treatment to obtain raw gas, tar, crude benzene and coke; wherein the assistant is medium-order coal, a mixture of the medium-order coal with the low-order coal, an organic binding agent or a mixture of the organic binding agent with the low-order coal. By the arrangement, material cost of oil gas and coke products can be reduced, resource utilization of biomass and rubbish can be further realized efficiently, and considerable economic benefits and certain social benefits can be achieved; the problem about limited application of the biomass and the rubbish due to nonexistence of large-scale industrial equipment in the prior art is solved, and shortcomings that an existing stamp-charging coke oven is low in utilization and surplus in upgrading industrial capacity are overcome.

Description

technical field [0001] The invention relates to the production field of gasification coke, in particular to a process for upgrading the molding material containing low-rank coal, biomass and garbage. Background technique [0002] Since the 18th century, coal has become one of the widely used energy sources in the human world. In terms of my country's energy consumption structure, coal currently accounts for about 70% and is the main energy source for the survival of the people. According to the different structure and composition, coal is divided into three categories: lignite, bituminous coal and anthracite. Bituminous coal is further divided into low metamorphic bituminous coal and medium metamorphic bituminous coal. coal". According to statistics, my country's low-rank coal reserves account for more than 55% of the country's proven coal reserves, up to 561.2 billion tons. However, because low-rank coal is the product of the initial coalification process, it has low carbo...
