Title: Способ получения низших олефинов
Inventor: BUKHARKIN A K
IPC: C10G11/02
Filed: 2000-02-07
Granted: 2001-06-20
Abstract: Изобретение относится к получению низших олефинов пиролизом углеводородного сырья и может быть использовано как в химической, так и в нефтехимической промышленности для производства полупродуктов органического синтеза. Способ получения низших олефинов проводят пиролизом углеводородного сырья в трубчатых реакторах при температурах стенки реактора 660 - 860°С в присутствии каталитической насадки с развитой поверхностью контакта, изготовленной из ферромагнитного сплава, содержащего (15 ± 1)% хрома и по (1,5 ± 0,5)% алюминия, молибдена и никеля. Сырье и материал катализатора перед поступлением в реакционную зону подвергаются комплексной обработке СВЧ-полями с круговой поляризацией и электронно-программируемой модуляцией. Подобный процесс позволяет получать газообразование на уровне 70,7 мас.% при выходе олефинов до 54,9 мас.%, в том числе этилена до 27,8%, пропилена до 15,3%, суммы бутиленов до 8,1% и дивинила до 8,2 мас.% от сырья, которым может служить прямогонная керосиногазойлевая фракция. Активация катализатора комплексным СВЧ-облучением позволяет в несколько раз снизить выход кокса при пиролизе.

Granted: 2001-02-27
Abstract: FIELD: mechanical engineering. SUBSTANCE: gearing has a body, coaxial driving and driven shafts with gears and intermediate gears of the first and second stages engages with them mounted on their supports and coupled to each other by intermediate shafts. Number of splines on spline shafts is different at opposite ends. Spline shafts are made for couping of device to them intended for their displacement. After installation of the first-line spline shafts, the second-line spline shafts are installed in succession with gearing loaded by normalized torque and rated axial force is applied to each spline shaft installed. In case of free axial displacement of one of spline shafts its angular position is changed, and operation of loading by torque and checking by axial force is repeated prior to assembly of all gearing lines, which ensures preset accuracy of power distribution over lines.
