The goal of this work was to improve the reactivity of two common zeolites, namely clinoptilolite and SSZ-13, by treating them with sulfuric acid. The treatment enhanced zeolite reactivity via dealumination and decreased particle sizes, which led to increased reactivity with calcium hydroxide, as ...
A. Hydrochloric acid, sulfuric acid, and nitric acid. B. Sodium hydroxide, potassium hydroxide, and calcium hydroxide. C. Sodium chloride, potassium chloride, and calcium chloride. D. Water, carbon dioxide, and oxygen. 相关知识点: 试题

Fluorapatite is treated with 93% sulfuric acid to produce calcium sulfate, hydrogen fluoride (HF) and phosphoric acid. The HF is removed as hydrofluoric acid. The overall process can be represented as: Ca5F(PO4)3 + 5 H2SO4 + 10 H2O → 5 CaSO4 2 H2O + HF + 3 H3PO4 ...
Aluminum compounds are treated under anhydrous conditions to prevent violent reactions, recover solvent, and form Al compounds suitable for landfill by reaction with anhydrous hydrolysis agent, eg calcium hydroxide. /Aluminum compounds/SRP: The most favorable course of action is to use an alternative ...

1 mL of 1 M sodium hydroxide is equivalent to 49.04 mg of H2SO4. STORAGE In an airtight container. Sulfuric Acid USP NF Grade Specifications: H2SO4 --- 98.08 Sulfuric acid [CAS 7664-93-9]. Sulfuric Acid contains not less than 95.0 percent and not more than 98.0 percent, by weight,...
The temperature would increase to 50–52°C by addition of calcium hydroxide, and thereafter the mixtures were kept stirring at 50°C for 30 min. After detoxification, the liquid was separated and re-acidified to pH 5.5 with sulfuric acid, followed by passing through a 0.22 μm membrane...
As a result, 89% of xylan conversion was attained along with 22mg of xylose decomposition at 121掳C with 0.2M sulfuric acid for 120min. In addition to this, prehydrolyzate liquors were detoxified with calcium hydroxide [Ca(OH) 2 ] at different pH levels (i.e., 8.5鈥 11.5) to ...
