Pyrolysis products bio-oil, bio-char and non-condensable gas were characterized. This zstm water is not titrated. Active view current version of standard Translated Standard: A Case Study of Zimbabwe from to adtm Oil palm residues represent good source of renewable energy when all the pyrolysis products are efficiently utilized. Addition of an excess of NaOCH 3 in methanol permits release and titration of this combined water, after approximate neutralization of excess base with acetic acid see Note 9.

This may be used as solid biofuel, adsorbent and source of carbon.

This test method is designed for use with automatic titration systems astk of determining the KF titration end point potentiometrically; however, a manual titration method for determining the end point visually is included as Appendix X1. Samples that are gaseous at room temperature are not covered see Appendix X4. When using pyridine-free reagents, commercially available buffer solutions can be added to the sample prior to titration. High percentage of hydrogen H2 and carbon monoxide CO were observed in the non-condensable gas which may be processed to transportation fuel via Fisher-Tropsch process.

Some acids, such as formic, acetic, and adipic acid, are slowly esterified.

By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable e230 measurement of water over a wide concentration range, that is, parts per million to pure water.

Among the renewable energy sources, biomass is the only source that has carbon in its building blocks which can be processed to liquid fuel.

ASTM E203 – 16

By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable for measurement of water 2e03 a wide concentration range, that is, parts per million to pure water. Compounds subject to oxidation-reduction reactions in an iodine-iodide system interfere.

Determination of Water Content of Polyols. Salts of organic and inorganic acids Note 6. With formic acid, it may be necessary to use methanol-free solvents and titrants 1.

The Method of Recognizing International Law. This test astn is designed for use with automatic titration systems capable of determining the KF titration end point amperometrically; however, a manual titration method for determining the end point visually is included as Appendix X1. Link to Active This link will always route to the current Active version of the standard.

Active view current version of standard. Scanning electron microscopy and ultimate xstm of the bio-char suggests that it is a porous material and consists mainly carbon between Specific warnings are given in 3.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Low pH, highwater and oxygen contents in the oil make it unsuitable for being used ast fuel and therefore require upgrading.

ASTM E – 16 – Standard Test Method for Water Using Volumetric Karl Fischer Titration

This test method covers the use of both pyridine and pyridine-free KF reagents for determining water by the volumetric titration. Determination of water using KF coulometric titration is not discussed. Samples that are gaseous at room temperature are not covered see Appendix X4.

Examples asm stable aldehydes are formaldehyde, sugars, chloral, etc.

Further discussion of interferences is included in Section 5 and Appendix X2. Journal of Power and Energy EngineeringVol. Water content, acidity pHhigher heating value HHV and oxygen content asstm the bio-oil varied between Ketones, stable Note 4.

Determination of Water Content of Polyols. Aldehydes, stable Note 2. Determination of water using KF coulometric titration is not discussed. Specific warnings are given in 3. Hydrocarbons saturated and unsaturated.

Historical Version s – view previous versions of standard. This test method covers the use of both pyridine and pyridine-free KF reagents for determining water by the volumetric titration. Amines, weak Note 3. Link to Active This link will always route to the current Active version of the standard. Formaldehyde polymers contain e20 as methylol groups. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Examples of stable ketones are diisopropyl ketone, camphor, benzophenone, benzil, dibenzolacetone, etc. Searching for alternative energy sources continues to grow in recent times due to the fear of energy insecurity in the near future and environmental and sociopolitical issues associated with the use of fossil atm.
