Aldehydes, stable Note 2. Samples that are gaseous at room temperature are not covered see Appendix X4. Among the renewable energy sources, biomass is the only source that has carbon in its building blocks which can be processed to liquid fuel. Oil palm residues represent good source of renewable energy when all the pyrolysis products are efficiently utilized.

By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable for measurement of water over a wide concentration range, that is, parts per million to pure water. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Determination of water using KF coulometric titration is not discussed. This may be used as solid biofuel, adsorbent and source of carbon. 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.

Hydrocarbons saturated and unsaturated. This test method covers the use of both pyridine and pyridine-free KF reagents for determining water by the volumetric titration. Some acids, such as formic, acetic, and adipic acid, are slowly esterified. It is the asmt of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test method 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. When using pyridine-free reagents, commercially available buffer solutions can be added to the sample prior to titration. This test method is designed for use with automatic titration systems capable of determining the KF titration end point potentiometrically; however, a manual titration method for determining the end point visually is included as Appendix X1.

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

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