Abstract

The invention discloses a method for preparing fuel oil by catalyzing and cracking papermaking waste residues with the utilization of solid super strong acid, and aims to solve the problem that papermaking waste residues generated from the recovery and reuse of waste paper are not effectively utilized and bring enormous pressure to the environment. The method provided by the invention comprises the following steps of: drying the papermaking waste residues until the moisture content is below 5%; crushing, putting a crushed substance into a pyrolysis kettle, followed by a cracking reaction at the temperature of 100-500 DEG C for 0.5-10 hours under the action of a solid super strong acid catalyst, pouring a liquid obtained from the cracking reaction after the cracking reaction into a distillation kettle, respectively collecting to obtain a gasoline fractionation segment at the temperature of 40-190 DEG C and a diesel oil fractionation segment at the temperature of 250-330 DEG C. The method provided by the invention is simple and easy to operate, requires low production cost, can be used to effectively catalyze and crack the main component plastic waste of papermaking waste residues for the preparation of fuel oil, change waste into valuables and mitigate environmental pressure, and is especially suitable for a certain scale of industrial production.

Description

technical field [0001] The invention relates to the technical field of papermaking waste residue treatment, in particular to a method for preparing fuel oil by catalytically cracking papermaking waste residue with solid superacid. Background technique [0002] Waste paper recycling is an effective way to solve the shortage of raw materials for papermaking. It can save resources and reduce costs. It is an important measure for my country's paper industry to solve the problem of fiber raw materials. However, a large amount of waste residue will be produced after utilizing waste paper to make paper. The production and sales of hundreds of paper mills in Fuyang City, Zhejiang Province account for more than 60% of the domestic market. According to statistics, more than 2,000 tons of waste residues are generated every day. After analysis, the main component of waste residues is waste plastics, and the annual waste plastics production is 151,200 tons. Because plastic waste is not ...
