The method is used to obtain values of the plastic properties of coals and blends used in carbonization and in other situations where determination of plastic behaviour of coals is of practical importance.

Rheology of Coal

For this analysis, 5 grams of minus 40 mesh prepared coal is packed into a retort barrel along with a stirrer. A constant torque is applied to the stirrer and the coal is heated at 3C/minute. As the coal softens, the stirrer begins to turn. The maximum fluidity value of your sample is expressed in dial divisions per minute (DDPM) of the stirrer rotation.

Both the heat-treated and untreated coal extracts were further investigated by elemental analysis, thermogravimetric analysis, solid-state 13 C nuclear magnetic resonance, and X-ray diffractometry, and it was found that the heat treatment will increase the degree of graphitization. The aromatic carbon content was found to correlate significantly with the fluidity of coal, and the relationship

3.1. ESI FT-ICR MS analysis of shale oil and coal tar Figure 1 illustrates negative-ion ESI FT-ICR MS spectrums of LSO and SLTCT. It is clearly seen that the molecular weight range of LSO is wider than that of SLTCT. The peaks with masses of LSO are within the molecular weight range of 150-600 Da, while the m/z values of SLTCT are from 100 to 350. Being lower than 600, these m/z values

10.03.2020Phase changes of the porous coal structure are connected mainly with its chemical properties. Over the last decades, attempts were made to do it based on structural analysis of coal itself as well as its extraction, oxidation, hydrolysis or pyrolysis products [10, 15, 16].Nevertheless, up until now, a specific single chemical formula was not proposed.

Slagging and fluidity behavior of coal ash under gasifier

The objective of this study is to predict the slagging and fluidity behavior of coal ashes from the physical/chemical properties of parent coals to determine the optimum operating parameter of a slagging-type coal gasifier. Three types of coal samples, such as Alaska Usibelli, China Datong and Posco (blended coal), are analyzed for their ash composition and ash fusion temperature. To

To investigate the relevance of th e amount of low -density polyethylene (LDPE) on coal fluidity development and coking pressure generation, Gray -King pyrolysis at three different temperatures was carried out using a coking coal and its blends with up to 10 wt% additions of LDPE. The structure and morphology of the semicokes could be a useful way to elucidate the mechanism of the interactions

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The Gieseler plastometric characterization of the American Pittson coal gave maximum fluidity, temperature range, Gieseler ratio 1(A1), Gieseler ratio 2(A2) of 2218 ddpm, 0.20, 4.13 respectively. The free swelling index analysis and determination for volatile matter content gave 7 and 27.15%, respectively.
