An interpolymer of ethylene and at least one alpha-olefin is claimed, wherein the ethylene interpolymer is characterized as having an average Mand a valley temperature between the interpolymer and high crystalline fraction, T, such that the average Mfor a fraction above Tfrom ATREF divided by average Mof the whole polymer from ATREF (M/M) is less then about 1.95 and wherein the interpolymer has a CDBI of less than 60%. The interpolymer of ethylene and at least one alpha-olefin can also be characterized as having a high density (HD) fraction and an overall density such that % HD fraction&#x3c;&#x2212;2733.3+2988.7x+144111.5 (x&#x2212;0.92325)where x is the density in grams/cubic centimeter. Fabricated articles comprising the novel interpolymers are also disclosed.

A method is disclosed for upgrading run-of-the-mine (ROM) lignites to remove the gangue (clays, rock etc.) which form ash when the lignite is burned. The unique features of the process, a combination of unit operations in a specified sequence, result in less loss of combustible fuel value without hydrodegradation (the production of a large volume of fines) normally associated with contact of the lignite with water as in pipeline transport of lignite.
