Embodiment 1

[0033] Embodiment 1, the present invention utilizes cephalosporin residue to prepare biomass fuel

[0034] Specifically include the following steps:

[0035] Step (1): the bacterial liquid produced after the fermentation of the cephalosporin is processed by high pressure plate and frame filtration, and the content of halogen and alkali metal is checked on the filter residue. The qualified filter residue is processed in the next step. During high pressure plate and frame filtration, perlite is added to help improve the filtration efficiency. The amount of perlite added is 3%, and the operation is stopped when the final plate and frame pressure reaches 1.6MPa.

[0036] If unqualified filter residues are obtained, the high-pressure plate and frame filtration treatment is performed again until the filter residues are qualified. The qualified standard of the filter residue is that the halogen content is less than or equal to 0.3%, and the alkali metal content is less than or equa...

Abstract

The invention provides a method for preparing biomass fuel by using cephalosporin residues, and relates to the technical field of biofuel. The method comprises the following steps: carrying out high-pressure plate frame filtration treatment to obtain filter residues with the halogen content of less than or equal to 0.3% and the alkali metal content of less than or equal to 0.4%, and drying the filter residues until the water content is lower than 25% to obtain the biomass fuel. The biomass fuel has a very high heat value and good combustion performance; meanwhile, the biomass fuel is high in calcium content, can play a role in sulfur fixation under the condition that a sulfur fixation agent is not added, and is beneficial to reducing the desulfurization load of combustion tail gas; moreover, the biomass fuel is low in halogen content and alkali metal content and small in damage to equipment during combustion, and the problem that the combustion equipment is corroded when the cephalosporin residues are combusted as the biomass fuel is solved. Besides, the biomass fuel prepared from the cephalosporin residues meets the requirements of national hazardous waste disposal and utilization standards, the disposal cost of the cephalosporin residues can be effectively reduced, and the method has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of biofuels, in particular to a method for preparing biomass fuels by utilizing cephalosporin residues. Background technique [0002] With the development of global industrialization, the use of traditional energy sources such as coal and oil has shown an exponential growth trend, which has gradually caused global energy shortages and rising prices. In this context, new alternative energy sources such as hydrogen energy and solar energy have been continuously developed and utilized, and the technological development of biomass energy has received particular attention from the industry due to its abundant raw material resources and high comprehensive utilization value. [0003] Antibiotic residue is the remaining fermentation residue after the production of antibiotics by microbial fermentation and metabolism. After the antibiotic bacterial residue is dried, the organic matter content in the dry matter reach...
