Corrigendum to: Kah, S.H., Joanna Jo, E.C., Sim, Y.C., Chin, K.C. (2013). Bulletin of Chemical Reaction Engineering & Catalysis, 8(1): 77-82. (doi:10.9767/bcrec.8.1.4569.77-82). In Abstract, typed as: “….. Due to information paucity, the physicochemical characteristics of the commercially obtained regener-ated Pt-Sn/Al2O3 catalyst (operated in moving bed reactor) and coke formation at different tempera-tures of reaction were discussed…..”In the Abstract, the phrase of “(operated in moving bed reactor)” should be deleted.
Erratum: Kah, S.H., Joanna Jo, E.C., Sim, Y.C., Chin, K.C. (2013). Bulletin of Chemical Reaction Engineering & Catalysis, 8(1): 77-82. (doi:10.9767/bcrec.8.1.4569.77-82).In Abstract section, the phrase of “(operated in moving bed reactor)” was deleted.Therefore, the sentence in the Abstract was corrected to: “….. Due to information paucity, the physico-chemical characteristics of the commercially obtained regenerated Pt-Sn/Al2O3 catalyst and coke for-mation at different temperatures of reaction were discussed…..”.

In order for Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group to publish and disseminate research articles, we need non-exclusive publishing rights (transfered from author(s) to publisher). This is determined by a publishing agreement between the Author(s) and Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group. This agreement deals with the transfer or license of the right for publishing to Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group, while Authors still retain significant all copy rights to use and share their own published articles. Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in any databases.
As a journal Author, you have all copy rights for a large range of uses of your article, including use by your employing institute or company.
