- W85156919 abstract "Steam pretreatment is the reaction of coal with steam at temperatures well below those usually used for solubilization. The objective of the proposed work is to test the application of steam pretreatment to coal liquefaction. A 300 ml stirred autoclave for liquefaction tests is being installed. Pretreatment and extraction tests were made with Blind Canyon coal alone, mixed with Illinois No. 6 coal, impregnated with iron, and impregnated with iron and sulfided using phenyl disulfide. Measurements show an increase in volatiles yield and a decrease in extraction yield with catalyst addition. These results are not yet definitive, because both yields may be artificially decreased by insoluble residue from phenyl disulfide. About one ram of purified {alpha}-naphthylmethyl phenyl ether was prepared and an additional 0. 8 gram were synthesized. Steam pretreatment of the model compound {alpha}-benzylnaphthyl ether was repeated with a Pyrex liner for the reactor tube. No differences have yet appeared as a result of using this liner (compared to bare stainless steel), evidence against any catalytic wall effect." @default.
