Problems solved by technology

However, hydrofluoric acid is a highly corrosive and highly toxic substance, and its removal effect on magnesium and calcium is insufficient.
Further, in the above method, there is a problem that the content of metal components in each plant-derived material deviates

Embodiment 1

[0096] 3 kg of coconut shells (produced in the Philippines and Mindanao) were put into a single-shaft crusher (Plastic Crusher 1005 manufactured by Yoshida Seisakusho) and crushed while scraping off the surface layer. Then, it was made to pass through the sieve of diameter 8mm attached to the discharge port of a single-shaft crusher, and the coconut husk (henceforth called crushed coconut husk) which had finished particle|graining was collect|recovered by this. Then, for 3 kg of broken coconut shells, according to the above-mentioned method for determining the average cross-sectional size, sieve to determine the average cross-sectional size, and simultaneously reclaim 120 g of coconut shells with an average cross-sectional size of 3.4 mm or more (on the 2.8 mm sieve), and soak them in 0.04M lemon 280 g of the acid aqueous solution was demineralized for 4 hours while stirring at 95°C. Then, it cooled to room temperature, deliquored by filtration, and the coconut shell was colle...

Embodiment 2

[0098] In Example 1, carbides were produced in the same manner as in Example 1 except that a sieve with a diameter of 11.5 mm was used instead of a sieve with a diameter of 8 mm.

Embodiment 3

[0100] In Example 1, carbides were produced in the same manner as in Example 1 except that a sieve with a diameter of 14.5 mm was used instead of a sieve with a diameter of 8 mm.

Abstract

The present invention is a carbon precursor composed of a chip having average cross-sectional dimensions of 4-35 mm, inclusive, determined by a sieving method, and relates to a carbon precursor derived from a plant material in which the content of a fibrous material having a length of 5 mm or more and a width of 2 mm or less is 6 wt% or less.

Description

technical field [0001] The present invention relates to a carbon precursor useful in the production of carbonaceous materials such as conductive materials, catalyst supports, and activated carbon, and a method for producing the same. Background technique [0002] Carbonaceous materials are used in various applications such as electrodes for capacitors, electrodes for electrolysis, activated carbon, and supports, and are fields and raw materials that are expected to be further developed in the future. Conventionally, these carbonaceous materials have been manufactured using coconut shells, coal coke, coal or petroleum pitch, furan resins, phenolic resins, and the like as raw materials. In recent years, the use of fossil fuel resources has had an impact on the global environment, and it is expected that their use will become difficult in the future due to the high price due to the decrease in their reserves. [0003] Therefore, carbonaceous materials manufactured from earth-f...
