FIELD: oil and gas production. ^ SUBSTANCE: invention refers to procedure for production of semi-finished product. The procedure consists in contacting oil stock with one or more catalyst at presence of a source of gaseous hydrogen for production of a common product containing a semi-product and gas and in separation of common product into semi-product and gas. The semi-finished product here corresponds to liquid mixture at 25C and 0.101 MPa and has contents of micro-carbon residue (MCR) as high, as 90% of MCR contents in oil stock wherein contents of MCR amounts to at least 0.0001 gram per gram of oil stock. Also, content of MCR is determined by the method of ASTM D4530. At least one catalyst is the catalyst on base of metal of group 6 of periodic table with average diameter of pores at least 90 à. Volume of pores with diameter at least 350 à amounts to as much, as 15% of volume of pores of carrier, wherein diameter of pores and volume of pores is determined by the method of ASTM D4282. Contact is performed at temperature 50-500C, pressure 0.1-20 MPa, hour volume rate of flow of oil stock 0.05-30 hour-1 and ratio of gaseous hydrogen in source of gaseous hydrogen to flow of oil stock 0.1-100000 nm3/m3. The invention also refers to catalyst for production of semi-finished product and to procedure of production of catalyst for output of semi-finished product. ^ EFFECT: production of semi-finished product with characteristics more improved, than characteristics of source oil stock. ^ 24 cl, 6 ex, 4 tbl, 8 dwg |
