This study investigated kinetics of torrefaction-induced weight loss in Pinus caribaea and Leucaena leucocephala grown in Nigeria, between 225\u2013300\u00b0C and axial stem position (top, middle, base). Oven-dried samples (300 g) were torrefied in a fixed-bed reactor under oxygen-limited conditions. Apparent rate constants were derived using a pseudo-first-order Arrhenius model. A total of 72 experimental runs were conducted. The sample weight loss increased with temperature. Pinus caribaea exhibited higher rate constants (0.0136\u20130.0761 min\u207b\u00b9) and lower activation energies (48.6\u201356.8 kJ.mol\u207b\u00b9) compared to Leucaena leucocephala. Axial variation significantly influenced activation energy, with base sections exhibiting 15\u201322% higher values than top sections. These findings demonstrate that biomass heterogeneity strongly affects reactor-scale torrefaction kinetics and should be considered in feedstock selection, process optimisation, and industrial-scale thermochemical conversion systems.<\/p>\n","protected":false},"author":6,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5518],"tags":[5581,5580,5582,5578,5579],"release_year":[],"ppma_author":[5552,5553,5554],"class_list":["post-5981","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-71-number-2-2026","tag-axial-heterogeneity","tag-fixed-bed-reactor","tag-thermochemical-conversion","tag-torrefaction-kinetics","tag-tropical-biomass"],"featured_image_src":null,"author_info":{"display_name":"Katar\u00edna Kalu\u017en\u00e1","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/kaluznavupc-sk\/"},"authors":[{"term_id":5552,"user_id":0,"is_guest":1,"slug":"francis-akinyele-faruwa","display_name":"FRANCIS AKINYELE FARUWA","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5553,"user_id":0,"is_guest":1,"slug":"olusola-olorunfemi","display_name":"OLUSOLA OLORUNFEMI","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5554,"user_id":0,"is_guest":1,"slug":"iyiola-ebenezer","display_name":"IYIOLA EBENEZER","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5981","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=5981"}],"version-history":[{"count":2,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5981\/revisions"}],"predecessor-version":[{"id":5997,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5981\/revisions\/5997"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=5981"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=5981"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=5981"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=5981"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=5981"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
