Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this article, the effect of gelatin as a binder to obtain granular activated carbon by joint processing of rice waste (husk and straw) and oil sludge was studied.Carbonation and activation of the granules were carried out in a hightemperature vacuum tube furnace of the BR-12 NFT series with a length of 200 mm, in a heating tube made of quartz glass with a length of 300 mm and a diameter of 60 mm.Carbonation was carried out at a temperature of 500°C, activation-by water vapor at a temperature of 850°C, at a ratio of water and carbonizate 2:1.The effect of the ratio of gelatin binder, rice waste and oil sludge on the properties of the activated carbon was studied.The optimal ratio of the joint processing of the mixture is rice husk: oil sludge: gelatin = 9:1:2 (by weight).The studies were carried out according to the following indicators: adsorption activity for iodine, total pore volume for water, mass fraction of moisture, adsorption activity for methylene blue, and bulk density.Granulated activated carbon corresponds to the BAU-MF brand.
