TH3196A - Process for the production of hydrocarbons - Google Patents

Abstract

In the preparation of hydrocarbons from synthetic gases on Co / Zr / SiO2 catalysts. It is prepared by diffusion, saturation and / or massaging a stationary bed catalyst, which provides a defined relationship between the outer surface (Se) and the inner (Si) so that C + 5 is formed. Selectiviti at height Bed catalysts should have Se (between 5 and 70 sq cm / ml) and Si (between 10 and 400 sq m / ml), as given in relation to the following, 106 is less than Se2 x Si> 2.5 x 104.

Claims (9)

1. The process for preparing hydrocarbons by a reaction using a carbon monoxide catalyst with hydrogen. Which exhibits characteristics that the carbonoxide and hydrogen mixture is exposed to the catalyst at high temperature and pressure. The catalist has 3-60 cobalt Section by weight And at least one other metal selected from cherconium, titanium and 0.1-100 parts chromium by weight per silica-alumina or silica-alumina. 100 parts by weight, this catalyst is prepared by massage and / or diffusion that characterizes the catalyst in a stationary bed form. And that the bed catalyst has an external surface area (Se) between 5 and 70 square centimeters / millimeter. And the internal surface area (Si) between 10 and 400 square meters / ml. As given in relation to 106> Se2 x Si> 2.5 x 104 2. The process, as assumed in claim 1, illustrates that the bed catalyst has Se between 10 and 50 sq cm / ml and Si between 15 and 200 sq m / ml. As it would give 2.5 x 105 correlation less than Se2 x Si> 3 x 104. 3. The process, as held by claim 1 or 2, that characterizes that the catlist provides an affinity (chemical formula) L = the total amount of colballs available on the catlist. Shown in milligrams of Co / mL, Si = internal surface area of the catalyst expressed in sq m / ml and R = weight ratio between the cobalt content given to the catalyst by massage And the total amount of cobalt available on the catalist 4. The process, as set forth in one of the claims 1-3, characterizes that the catalist contains 15-50 parts of cobalt by weight per 100 parts of the substrate. And other metals 0.1-5 parts by weight If in preparation the cobalt is added first and then another metal or another metal is 5-40 parts by weight. If in the preparation of another metal to go down first and then cobalt 5. The process, as set forth in one of the claims 1-4, characterizes that the catalist contains zirconium as another metal and silica as the substrate. 6. The process, as held by one of Clause 1-5, is characterized by that the process is performed at a temperature of 125-350C and a pressure of 5-100 bar. 7. The process, as it holds, in one of the claims 1-6, showing the nature of the H2 / CO mixture, there is a mole ratio of H2 / CO between 1.75 and 2.25. 8. Process, as set forth in one of Claims 1-7, that characterizes the preparation of central distillates from at least part of the cobalt catalyst-based product, where It has an initial boiling point higher than the final boiling point of the heaviest central distillate desired as the final product. Here, one or more noble metals of group VIII on substrate at high temperatures and pressures are subjected to hydrocracking. 9. The process, as assumed in Clause 8, illustrates the nature that in hydrocracking processes one or more noble metals of group VIII0.1-2% are used by: Weight 1 0. The process, as it assumes, in any of the claims 8-9 claiming the nature that in the hydrocreking process, platinum-based catalysts are used. Or palladium, a noble metal of group VIII and silica-alumina as a supporting agent.
