Embodiment 1

[0067] This example illustrates the advantages of the method of the present invention compared to conventional visbreaking methods. The raw materials in Table 1 (acid value 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 raw material vapor with a 40% wt KOH solution and then mixing it with a nickel acetate solution in a K:Ni weight ratio of 4:1. The catalytic emulsion is mixed with the raw materials, so that the potassium is 1000ppm based on the raw materials, and the nickel acetate is 250ppm, and the reaction mixture is placed under steam reforming conditions, including: the temperature is 430 ° C, LHSV = 2h -1, 8%wt steam based on feedstock (method 1). The emulsion and feedstock 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.
