Abstract

The invention discloses a method for preparing synthesis gas by co-processing a waste printed circuit board and an organic waste liquid, a heavy product obtained by low-temperature pyrolysis of the waste printed circuit board, waste lubricating oil and the organic waste liquid are used for preparing multi-element slurry for a synthesis gas preparation process, organic matters in the three wastes are fully utilized, and meanwhile, clean water resources are saved; the method has the characteristics of being high in resource utilization efficiency, turning waste into wealth and being environment-friendly, meanwhile, the debromination effect is good, and the problems that in the prior art, when the waste printed circuit boards are subjected to pyrolysis treatment, the recovery value of nonmetal parts is low, liquid products are difficult to utilize and the debromination effect is poor are solved.

Description

Technical field: [0001] The invention relates to the technical field of resource recycling and utilization, in particular to a method for co-processing waste printed circuit boards and organic waste liquid to prepare synthesis gas. Background technique: [0002] The harmless and resourceful recycling of waste printed circuit boards is an urgent problem to be solved in countries all over the world. Printed circuit boards are composed of metal parts and non-metal parts, among which metal parts have high resource recovery value and are currently the focus of industrialized recycling of waste printed circuit boards. Because the economic value of recycling non-metal parts is generally lower than that of metal parts, the recycling of non-metal parts of waste printed circuit boards is currently neglected, but resin and glass fiber in non-metal parts account for more than 60% of the total weight of circuit boards, and among them Contains brominated flame retardants. If the organic...
