Embodiment 1

[0067] This example illustrates the advantages of the method of the present invention compared to conventional viscosity reduction methods. The starting materials of Table 1 (acid number 25 mg KOH / g) were used to prepare the catalytic emulsion of the present invention using potassium and nickel. The catalytic emulsion was prepared by first mixing the feed steam with a 40% wt KOH solution and then mixing it with a nickel acetate solution with a K:Ni weight ratio of 4:1. The catalytic emulsion was mixed with the raw materials so that the potassium was 1000 ppm and the nickel acetate was 250 ppm based on the raw materials, and the reaction mixture was placed under steam reforming conditions, including: a temperature of 430° C., LHSV=2h -1, 8% wt steam based on feed (method 1). The emulsion and feed were processed in a cracker with a volume of 1.2 liters. The feed rate was 2400 g / h, while the rate of the catalytic emulsion was 113 g / h.

Abstract

The invention provides a method of preparing catalytic emulsion, which comprises: providing a acidic hydrocarbon steam; providing a first aqueous solution of a first alkali metal; mixing the acidic hydrocarbon steam and the first aqueous solution; providing a second aqueous solution of a second alkali metal; mixing the mixture and the second aqueous solution to get catalytic emulsion. The method of the invention is good for keeping the stability of the emulsion and insuring the droplet size small enough, and increases the conversion of heavy resid fraction or other raw materials, to get hydrocarbon productions.

Description

[0001] This application is a divisional application of Chinese Invention Patent Application No. 98101186.1. technical field [0002] The present invention relates to a steam reforming process, and a catalyst for high conversion conversion of heavy hydrocarbon feedstocks to more valuable light hydrocarbon products, and to a process for preparing the catalyst. Background technique [0003] Various methods are available for converting heavy hydrocarbons into more desirable liquid and gaseous products. These methods include visbreaking and extreme thermal cracking. However, these methods still suffer from the following disadvantages: low conversion, and / or high percentages of undesirable by-products such as coke; resulting in transportation and handling problems. SUMMARY OF THE INVENTION [0004] The main object of the present invention is to provide a steam reforming process which has good conversion and reduced amount of undesired by-products such as coke. [0005] Another...
