1493787 Making formcoke CONSOLIDATION COAL CO 8 July 1976 [10 July 1975] 28495/76 Heading CSE A process for the production of formcoke from non- or weakly-caking coal comprise the steps of (a) solvent extracting the finely divided coal in the presence of molecular hydrogen, (b) stripping ...
multilayered features offering multifunctionality which will increase the service lifetime of insulation and refractory components used in the solid oxide fuel cell, direct carbon fuel cell, furnace, metal melting, glass, chemical, paper/pulp, automobile, industrial heating, coal, and power generation ...
In a melting/gasifying furnace including a coke-filled layer, coal is gasified by oxygen blown through tuyeres into a hot reducing gas which is caused to ascend through the coke-filled layer so as to melt reduced iron supported on the top of the coke-filled layer. The resulting molten iro...
SiO2 under vaccum. The filtrate was treated with 0.5-1 wt.% active chorcoal based on the solids for 30-60min at 60-80鈮癈 with agitation, vaccum-concd. at 60鈮癈 or below, and seasoned to give the final product. Copyright 1997 KIPO 展开 ...
A blast furnace coal is produced by rapidly heating a coal blend having 10 to 30% by weight of a non-slightly-caking coal having softening initiation temperature T with the balance including a caking coal having softening initiation temperature T.sub.0 (T.sub.0 ≦T + 40° C.) at...

(deoxyribonucleic acid, orDNA) with the aim of achieving improvements in disease anddroughtresistance, product yield and quality,frosthardiness, and other desirable properties. However, such traits are inherently complex, and the process of making changes to crop plants through genetic engineering has ...
Non-porous membranes, also known as dense film membranes, are usually polymeric membranes above their glass transition temperature, making their behaviour liquid like. Since thermal stability of a material is significant, most polymers are operated above their glass temperatures ensuring long term ...
