  • Patent number: 11472755
    Abstract: Method of making BTX compounds including benzene, toluene, and xylene, including feeding heavy reformate to a reactor containing a composite zeolite catalyst. The composite zeolite catalyst includes a mixture of layered mordenite (MOR-L) comprising a layered or rod-type morphology with a layer thickness less than 30 nm and ZSM-5. The MOR-L, the ZSM-5, or both include one or more impregnated metals. The method further includes producing the BTX compounds by simultaneously performing transalkylation and dealkylation of the heavy reformate in the reactor. The composite zeolite catalyst is able to simultaneously catalyze both the transalkylation and dealkylation reactions.

  • Patent number: 9939837
    Abstract: Method for generating piecewise-affine multivariate functions, wherein the online computation of the search tree is performed in order to locate the input value in the polytopes of the partition, and the subsequent generation of the corresponding affine function. It also proposes a configurable and programmable device for generating piecewise-affine multivariate functions composed of an architecture with four functional blocks namely: a control unit block (1), a tree memory block, a parameter memory block and an arithmetic unit block; and it has at least three operating modes which can be selected using different values of a bus (config): writing of the tree memory, writing of the parameter memory and evaluating the affine function. It may include a fourth operating mode, which is the test mode.
