A new type pitch produced from crude petroleum was studied with a view to utilizing for production of metallurgical coke. This pitch has 0. 5-0. 6 C/H, about 200°C softeningpoint and high aromaticity. Adding to a charge coal for coke oven, the pitch increase the strength of the coke produced, and furthermore it was find that the qualities of the coke produced from some non coking coals are as good as some cokes from strongly coking coals.<BR>Moreover, it seems to the authors that application of hot briquetting technique to this pitch would has an advantages of the method in simple blending of the pitch to coals.<BR>On these results, the authors suggested some examples of system for production of "so called modified strongly coking coal" from non coking coals, and discussed these process.
