The latest heavy oil cracking catalyst

New heavy oil cracking catalyst
Spanish scientists have recently developed a new catalyst that can more effectively crack heavy oil into small molecular fuels and chemical raw materials
after the lighter components in crude oil are extracted, there are some heavier hydrocarbons with more than a dozen or more carbon atoms in each molecule. In order to produce fuel oil and chemical raw materials with only 2 to 3 carbon atoms per molecule, heavy oil needs to be cracked. At present, the zeolite catalyst widely used in heavy oil cracking is an aqueous alkali metal aluminosilicate, with regularly arranged holes suitable for cracking reaction. The parts take advantage of Alibaba's advantages in big data, e-commerce platform, Internet products, etc. on the one hand; On the other hand, combined with the existing marketing and huge logistics network of mine 5, build an offline intelligent logistics system. When hydrocarbon molecules enter it during process transfer or transportation, they can be cracked in a highly acidic environment. However, the width of the channel entering the hole is only 0.74 nm, which limits its catalytic effect
the new zeolite catalyst synthesized by Spanish scientists is similar to the traditional zeolite catalyst, but the number of channels in each hole has increased from 4 to 6. Preliminary tests show that the catalytic effect of this new material, known as "ITQ-21", is better than that of octahedral zeolite, and cracking undoubtedly puts forward higher requirements for the material. The product contains more octane and the quality of fuel oil is higher
