Embodiment 1

[0022] 1. Carbonization process: add 100 grams of dried bamboo chips to 30% H 3 PO 4 Soak in 1000 grams of aqueous solution for 20 hours, filter with Buchner funnel, take the filter cake and dry at 100°C for 24 hours to obtain bamboo chips impregnated with phosphoric acid, then pyrolyze in a tube furnace, that is, at a heating rate of 30°C / min Raise the temperature to 110°C, keep it warm for 3 hours, then cool down to room temperature (20°C) naturally, wash the product with deionized water until neutral, and dry to obtain bamboo charcoal.

[0023] 2. Sulfonation process: take 2 grams of the above bamboo charcoal, add SO 3 10 grams of fuming sulfuric acid with a mass fraction of 50%, heated to 100°C for sulfonation at a constant temperature for 2 hours, added deionized water to cool to terminate the reaction, filtered, and washed the filter cake with deionized water until no sulfate was detected with barium chloride aqueous solution ion, obtain 2.2 grams of bamboo charcoal su...

Abstract

The invention discloses a method for preparing fuel oil from waste paper waste residue, which comprises the following steps: pretreating waste residue generated after papermaking with waste paper; by using the pretreated waste paper waste residue as the raw material and bamboo charcoal sulfonated solid acid as a catalyst, carrying out cracking reaction at 100-500 DEG C for 0.5-10 hours; and after the reaction finishes, distilling the cracking liquid, and collecting the 40-330 DEG C fraction as the fuel oil. The method for producing fuel oil by using the solid acid catalyst does not generate solid waste, and thus, is environment-friendly; and the method disclosed by the invention is suitable for large-scale industrial production, is a green and clean production technique capable of changing wastes into valuable substances, and has no application reports of industrial production at present.

Description

(1) Technical field [0001] The invention relates to a technology for utilizing waste paper and residue, in particular to a green process technology that uses a novel carbon-based sulfonic acid type solid acid as a catalyst and utilizes cracking technology to produce oil from waste paper and residue. (2) Background technology [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. According to statistics, there are thousands of tons of waste paper and waste slag produced every day. After analysis, the main component of waste residue is waste plastics. Because plastic waste is not easy to rot, it seriously affects the ecological environment of the earth. Therefore, the treatment of wa...
