Method for producing green fuel by free radical treatment paper liquor waste slag and electrical catalytic reaction device

Abstract

The invention discloses a preparing method of green fuel by using free radical to deal with high concentration paper liquor waste slag and electrocatalysis reaction, which comprises the following steps: using electrochemical hydrated proton autoclave and initiating agent; cyclical generating hydroxyl group free radical (.OH), superoxide negative ion free radical (O2-), nitrogen-oxygen free radical (NO,NO2) and active oxygen (1O2, H2O2); proceeding free radical chain reaction with lignin, cellulose and hemicellulose and so on high molecular compound in electrocatalysis autoclave; proceeding electrolytic reduction; separating; dewatering; getting the product. This invention possesses simply craft and low cost, which can solve pollution caused by paper company.

Description

technical field The invention relates to the field of development and utilization of environmental resources and energy resources, and relates to a method of using free radicals to process high-concentration pulp black liquor waste residues to produce green fuels and an electrocatalytic reaction device for implementing the method. Background technique The paper industry is an important basic industry in the global industry. Its output value is higher than that of steel, aviation, and aerospace industries. It ranks third in the United States and fifth in China. However, the papermaking industry has also produced serious environmental pollution problems. According to the data of the State Environmental Protection Administration of China, the discharge of papermaking wastewater and the COD and SS emissions in papermaking wastewater still account for a high proportion of the total industrial discharge. , reaching 13%, 47.5% and 23.6% respectively. Especially in my country, mos...

Problems solved by technology

However, the above utilization measures have problems such as large project investment, complicated process, and low economic benefits for small and medium-sized papermaking enterprises, and still cannot fundamentally solve the problems of waste of resources and environmental pollution caused by emissions in this industry.
