Pulverized Wyoming subbituminous coal was beneficiated by low-pH oil agglomerationat CONSOL to prepare the coal for direct liquefaction. Conventional cleaning is not veryeffective in cleaning this coal; for example, conventional oil agglomeration only givesabout 20% ash rejection. To improve ash rejection, the coal-water slurry was acidifiedto a pH of about 0.5. Oil agglomeratio...

introduction: aloe vera compounds have inhibitory activity on fungi, bacteria, and viruses. this study examines the antibacterial activity of a. vera purified extracts including gel, boiled skin, boiled gel, and distilled extract against pathogenic bacteria, staphylococcus aureus, methicillin-resistant s. aureus (mrsa), klebsiella pneumonia and pseudomonas aeruginosa were elucidated. method: th...

Many patients use herbal supplements to treat chronic cardiovascular conditions and often combine herbal ingredients with cardiovascular medications. However, physicians do not reliably elicit a history of herbal use from their patients and may overlook herbal supplements' adverse effects. Although often considered harmless by patients, herbal supplements may cause adverse cardiovascular effect...

A dynamic model for the simulation of the batch operation of a multicomponent packed distillation column is developed. The accuracy of simulation code is verified by using two types of mixtures (cyclohexane-n-heptane-toluene and ethanol–water) theoretically and experimentally. An optimum internal reflux ratio profile is searched to maximize the distillate amount of a specified concentration for...

Asavas and aristhas are medicines prepared by fermentation. In some medicines alcohol produced by fermentation is distilled and added to the powdered drugs for a fixed period, filtered and the filtrate is used as medicines.Karpurasava is prepared by distilling the alcohol. The quantity of alcohol in the distillate was 9.87% by the textual method while it was 5.77% by glass distillation apparatu...

Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC) agent, enhancing our knowledge about their biologic func...

A study has been made of various methods of distillation of solutions of furfural and of xylose with the object of increasing the 88-percent yield of furfural obtained from xylose by the present standard m ethod of distillation. Sources of error that have been considered are: Decomposition of furfural, volatilization of furfural, effect of rubber stoppers used in the distillation procedure, inc...

The chemical and physical characteristics of Malaysian palm kernel and its products are discussed in this article. The main products derived from palm kernel are palm kernel oil, palm kernel olein and palm kernel stearin whereas the by-products are palm kernel meal and palm kernel fatty acid distillate. The major composition of the kernel is oil (49%), followed by carbohydrate (26.1%), protein ...
