Publication number: 20210162378Abstract: The current invention relates a process for making and using a bulk catalyst precursor (i.e. no support material is added as such) comprising Ni and Mo and/or W and an organic component, wherein the molar ratio of C:(Mo+W) ranges from 1.5 to 10. The bulk catalyst precursor is prepared from a mixture of metal-precursors with an organic agent. The organic agent is partly decomposed to form a mixed metal-oxide/C phase which is in effect the bulk catalyst precursor. This bulk catalyst precursor (i) is effectively insoluble in water (ii) does not have any appreciable pore volume or surface area and (iii) does not contain a (nano)crystalline metal-oxide phase as characterized by XRD.Type: ApplicationFiled: February 16, 2021Publication date: June 3, 2021Inventors: JACOB ARIE BERGWERFF, WILHELMUS CLEMENS JOZEF VEERMAN, RONALD JAN HUIBERTS, SONA EIJSBOUTS-SPICKOVA
