stearic acid Archives - Soap Queen

Dec 14, 2016· That's why cold process soap is so fantastic for sensitive skin, and why soap from the store can leave the skin feeling dry and overly "squeaky clean." While cold process soap has many skin benefits, one downside is that cold process soap does not last as long in the shower as soap made from surfactants and detergents.

Treatment processes in petroleum refining

Sulfuric acid is the most commonly used acid treating process. Sulfuric acid treating results in partial or complete removal of unsaturated hydrocarbons, sulfur, nitrogen, and oxygen compounds, and resinous andasphaltic compounds. It is used to improve the odor, color, stability, carbon residue, and other properties of the oil. Clay/lime ...

US5008226A - Process for making acid activated bleaching ...

A process for making acid-activated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower ...

Actal Acid Clay Catalyst, Acid Activated Clay Manufacturers

Clay works bi-functionally as an acid catalyst and adsorbent. Acid catalyst nature of clay enhances the reactions involving the olefins and aromatics. These reactions are typically alkylation, isomerisation and disproportionation. As a result of alkylation reactions BrI due to olefins is reduced to desired level.

Chapter 7.1 Acid Activation of Clay Minerals - ScienceDirect

One of the most common chemical modifications of clays, used for both industrial and scientific purposes, is their acid activation. This consists of the treatment of clay with a mineral acid solution, usually HCl or H 2 SO 4.The main task is to obtain partly dissolved material of increased specific surface area, porosity and surface acidity (Komadel, 2003).

Re-refining of Used Lube Oil, II- by Solvent/Clay and Acid ...

They may be recycled through the use of re-refining process to achieve useful products. This study compares two different re-refining processes. A laboratory scale setup of solvent extraction/clay and acid/clay-percolation processes were established to re-refine used oil collected from different sources.

Comparison of BERC re-refining process with acid/clay ...

Abstract. This report compares the economics of acid/clay re-refining with the economics of the BERC solvent re-refining process. The costs of re-refining using the BERC process have been studied in a previous report entitled ''Predesign Cost Estimate for Re-refined Lube Oil Plant'' prepared for the Bartlesville Energy Research Center.

Acid Clay Catalysts – Advanced Clay Technologies

Acid Clay Catalysts Brand Name: XYLACT™︎. Designed for selective Olefin removal from BTX, XYLACT™︎ is the most e fficient clay catalyst in the market for the selective removal of olefins from Benzene/Toluene and Heavy Reformate (mainly Xylenes). Other grades of XYLACT™︎ are available for removal of organic N compounds (NFM, NMP) from Benzene feeds used in …

Cyclonic distillation tower for waste oil rerefining process

Feb 20, 1979· The solvent extraction/acid-clay process is a relatively new concept and involves pretreatment of the dehydrated waste oil feed stock with relatively complex and costly solvents, followed by conventional acid treatment and clay contacting. While the solvent treatment increases product yields, the cost thereof is considerable and therefore ...

Processing Edible Oils - Penn State Extension

Figure 3: A bag of bleaching clay. A simple acid wash of the raw pressed oil will cause many of the hydratable compounds to settle out of the water and become particles that can be settled, centrifuged or filtered from the remaining oil. Citric acid is often chosen as the acid for this operation. In one process, the oil is heated to 80°C (176°F).

Physical Refining – Degumming | Oil Palm Knowledge Base

Dec 26, 2015· Acid degumming leads to lower residual phosphorus content than water degumming and, therefore, is a good alternative if dry degumming and physical refining are to be the next refining steps. The acid degumming process might be considered as a variant of the water degumming process in that it uses a combination of water and acid.

Characterization, Acid Activation, and Bleaching ...

The hydrochloric acid activation of the clay affects its physiochemical properties as shown in Table 3. Activation resulted in increase in acidity which showed a decrease in PH from 5.90 to 3.98 for the special case of raw and 3 M hydrochloric acid activated clay.

Make Alumina using Hydrochloric Acid

The most promising of several acid processes investigated appears to be HCl leaching of the clay followed by crystallization of AlCl3·6H20 by sparging with HCl gas. To obtain Al2O3 by this process, calcined clay is leached with 26-pct-HCl, a solid-liquid separation is …

Chemical Processing of Phosphate

After the phosphate is separated from the sand and clay at the beneficiation plant it goes to the processing plant. There it is reacted with sulfuric acid to create the phosphoric acid needed to make fertilizer. The principal fertilizer product of the industry is diammonium phosphate (DAP), made by reacting ammonia with the phosphoric acid.

High-Temperature Reaction of Kaolin with Sulfuric Acid ...

Jul 18, 2002· A new procedure is described in which kaolin and a small amount of concentrated sulfuric acid are heated in a furnace at temperatures between 150 and 1000 °C. Parameters studied were reaction temperature and time, proton to alumina molar ratio, calcination temperature and time, and amount of water in the reaction medium. Al yield grew sharply until …

Heap leaching - Wikipedia

The process chosen depends on the properties of the ore. The final product is cathode copper. Nickel ores. This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher ...

Clay - Wikipedia

Clay minerals typically form over long periods of time as a result of the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents.These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals …
