METHOD FOR COAL CONVERSION |
摘要 |
FIELD: mining. ^ SUBSTANCE: coal hydrogenization takes place in the presence of a catalyst comprising a molybdenum compound as a transition metal. Products of the coal hydrogenization are separated into liquid fractions and a solid residue that contains said transition metal. Sludge from the coal hydrogenization is mixed up with limestone and low-grade coal, and then incinerated. The liquid fractions are distilled and disposed of. Fly ash formed from burning the solid residue is collected and treated with a mixture of ammonia and ammonium carbonate. An obtained suspension is filtered and molybdenum compounds are extracted thereof in the form of an aqueous solution that is reused as a component of the catalyst for the coal hydrogenization. A solid residue from the suspension filtration comprising trace rare elements is treated with hydrochloric acid while being heated and then said trace rare elements are extracted thereof by a solution of three-n-butyl phosphate in kerosene oil. ^ EFFECT: invention allows combining the process of catalyst reactivation with the extraction of trace rare elements. ^ 1 tbl |
