Abstract

Se proporcionan procesos para la producción de olefinas de materias primas de hidrocarburo. En un aspecto, los procesos de la presente invención utilizan bobinas que pasan a través por un horno de pirólisis para convertir parcialmente una materia prima de hidrocarburo en olefinas, seguido de la conversión adicional de la materia prima de hidrocarburo en un reactor adiabático. Una porción de las bobinas en el horno de pirólisis transporta la materia prima de hidrocarburo y el resto sólo transporta el vapor. Después de un período de tiempo seleccionado, el material que fluye a través de las bobinas se permuta. Al hacer fluir el vapor a través de las bobinas que previamente contuvieron la materia prima de hidrocarburo, puede ocurrir una descoquización en línea. En otro aspecto, se utiliza un reactor de elevada temperatura para convertir el metano o gas natural en olefinas.
