Method for preparing activated carbon from peeled branch wood of initiated branches in eucommia bark leaf forest

Abstract

The invention belongs to the technical field of activated carbon preparation. The method comprises the followings steps of: with peeled eucommia branches in a eucommia bark leaf forest pattern as a raw material to prepare activated carbon, immersing the pretreated raw material and an activating agent in the presence of ultrasonic waves, and activating carbon for a certain period of time at certain temperature to obtain an activated material; and then, recovering the activating agent, rinsing, dehydrating, drying and the like to obtain the finished product of the activated carbon. The eucommia branches are unemployed wastes at present, so that the waste is employed. The invention not only solves the environmental problem, but also enlarges the raw material resources of the activated carbon and reduces the manufacturing cost of the activated carbon; and the purposes for comprehensively developing the eucommia bark leaf forest technology and manufacturing the activated carbon with high adsorption property are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of activated carbon production, and more specifically relates to a method for producing activated carbon by using peeled branches of eucommia leaf forest models as raw materials. Background technique: [0002] Most of the traditional activated carbon manufacturing processes are produced with expensive raw materials such as coal and wood. For today's scarcity of resources, this is obviously not a long-term solution. [0003] Eucommia ulmoides Oliv., single family, single genus, single species, is a rare and precious economic tree species unique to China, and also an important glue source plant with the widest adaptability in the world. It can be cultivated in most provinces of my country. The eucommia grove model belongs to the traditional cultivation model. The cultivated eucommia tree is tall, and it is difficult to collect seeds or leaves, and the cost of industrialization is high. If the bark is used, ...
