The reaction consists of a partial oxidation to propanal and complete oxidation to CO_2 and H_20, each of which progresses independently in parallel on own active sites. The rate of propanal formation indicates a characteristic oscillation. The oscillation seems to be a multiplicity caused by the switching between two different surface structures on each of which the partial oxidation progresses at different rate, high rate (γCHO^H) and low rate (γCHO^L). For γCHO^H andγCHO^L, the L-H and E-R models consistently explained all experimental data. Three rate equations for the two rates to form propanal and the complete oxidation are expressed γCHO^H =κCHO^HPc_3H_6^<0.25>Pn_2O^<0.42> γ^<CHOL>=κCHO^LPc_3H_6^<0.29>Pn_2O^<0.31> γCO_2=κCO_2Pc_3H_6^<0.36>Pn_2O^<0.81> The activation energies for propanal formation at high and low rates and for CO_2 formation were evaluated to be 9(±4)kJ/mol 92?218kJ/mol and 85(±5)kJ/mol, respectively. All the surface coverages of N_20, C_3H_6 and propanal during the reaction were evaluated to be θN_2O=0.13, θC_3H_6=0.69?1.17 and θCHO=0.15, respectively. θC_3H_6 is presumed to be a sort of trigger for the oscillating rate.","subitem_description_type":"Abstract"}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北見工業大学"}]},"item_2_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hiroshi, TAKEDA"}],"nameIdentifiers":[{"nameIdentifier":"33363","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tohru, KANNO"}],"nameIdentifiers":[{"nameIdentifier":"33364","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masayoshi, KOBAYASHI"}],"nameIdentifiers":[{"nameIdentifier":"33365","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"21-1-3.pdf","filesize":[{"value":"7.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"21-1-3.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6646/files/21-1-3.pdf"},"version_id":"4ea5e26b-30ef-4d8b-98cd-54a84f40f44e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Interpretation of the Multiplicity of Kinetics in Heterogeneous Catalysis*","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Interpretation of the Multiplicity of Kinetics in Heterogeneous Catalysis*"}]},"item_type_id":"2","owner":"1","path":["42"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-09"},"publish_date":"2007-04-09","publish_status":"0","recid":"6646","relation_version_is_last":true,"title":["Interpretation of the Multiplicity of Kinetics in Heterogeneous Catalysis*"],"weko_creator_id":"1","weko_shared_id":3},"updated":"2022-12-13T02:19:59.079640+00:00"}
