Abstract

A one-dimensional mathematical model was developed to simulate the performance of catalytic fixed bed reactor for carbon dioxide reforming of methane over Rh/Al2O3 catalyst at atmospheric pressure. The reactions involved in the system are carbon dioxide reforming of methane (CORM) and reverse water gas shift reaction (RWGS). The profiles of CH4 and CO2 conversions, CO and H2 yields, molar flow rate and mole raction of all species as well as reactor temperature along the axial bed of catalyst were simulated. In addition, the effects of different reactor temperature on the reactor performance were also studied. The models can also be applied to analyze the performances of lab-scale micro reactor as well as pilot-plant scale reactor with certain modifications and model verification with experimental data. © 2008 by Authors, Published by BCREC Group.

Journal Author(s) Rights

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. These Author copy rights can be exercised without the need to obtain specific permission. Authors who publishing in BCREC journals have wide copy rights to use their works for teaching and scholarly purposes without needing to seek permission, including, but not limited to:

use for classroom teaching by Author or Author's institution and presentation at a meeting or conference and distributing copies to attendees;
use for internal training by author's company;
distribution to colleagues for their reseearch use;
use in a subsequent compilation of the author's works;
inclusion in a thesis or dissertation;
reuse of portions or extracts from the article in other works (with full acknowledgement of final article);
preparation of derivative works (other than commercial purposes) (with full acknowledgement of final article);
voluntary posting on open web sites operated by author or author’s institution for scholarly purposes,

(but it should follow the open access license of Creative Common CC-by-SA License).

Authors/Readers/Third Parties can copy and redistribute the material in any medium or format, as well as remix, transform, and build upon the material for any purpose, even commercially, but they must give appropriate credit (the name of the creator and attribution parties (authors detail information), a copyright notice, an open access license notice, a disclaimer notice, and a link to the material), provide a link to the license, and indicate if changes were made (Publisher indicates the modification of the material (if any) and retain an indication of previous modifications using a CrossMark Policy and information about Erratum-Corrigendum notification).

Right Transfer Agreement for Publishing (RTAP)

The Authors submitting a manuscript do so on the understanding that if accepted for publication, non-exclusive right for publishing (publishing right) of the article shall be assigned/transferred to Publisher of Bulletin of Chemical Reaction Engineering & Catalysis journal (Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group).

Upon acceptance of an article, authors will be asked to complete a 'Right Transfer Agreement for Publishing (RTAP)'. An e-mail will be sent to the Corresponding Author confirming receipt of the manuscript together with a 'Right Transfer Agreement for Publishing' form by online version of this agreement.

Bulletin of Chemical Reaction Engineering & Catalysis journal and Masyarakat Katalis Indonesia-Indonesian Catalyst Society (MKICS), the Editors and the Advisory International Editorial Board make every effort to ensure that no wrong or misleading data, opinions or statements be published in the journal. In any way, the contents of the articles and advertisements published in the Bulletin of Chemical Reaction Engineering & Catalysis are sole and exclusive responsibility of their respective authors and advertisers.

Remember, even though we ask for a transfer of right for publishing (RTAP), our journal Author(s) still retain (or are granted back) significant scholarly copy rights as mentioned before.
