Despite th. fact th.t a few coun.ries in.th. Mediterran.an.an. th. Middle East h.ve limited crude oil reserves, th.y h.ve abun.an. biomass feedstocks. For in.tan.e, Jordan.relies h.avily on.th. importation.of n.tural gas an. crude oil for its en.rgy n.eds;but, by applyin. th.rmoch.mical con.ersion.tech.0}ques, leftover olive oil can.be used to replace th.se en.rgy sources. Un.erstan.in. th. ch.mical, ph.sical, an. th.rmal ch.racteristics of raw materials is essen.ial to obtain.n. th. most out of th.se con.ersion.processes. Th.rmogravimetric an.lysis was used in.th.s study to examin. th. th.rmal beh.vior of olive-solid residue (kern.l) at th.ee differen. h.atin. rates (5, 20 an. 40 C/min. in.n.trogen.an. oxygen.atmosph.res. Th. in.tial degradation.temperature, th. residual weigh. at 500 an. 700˚C an. th. th.rmal degradation.rate durin. th. devolatilization.stage (below 400˚C) were all determin.d. It was foun. th.t in.n.sub>2 an. O2 atmosph.res, both.th. in.tial degradation.temperature an. th. degradation.rate in.rease with.in.reasin. h.atin. rates. As h.atin. rates in.rease in.th. n.sub>2 atmosph.re, th. residual weigh. at 500 or 700˚C decreases sligh.ly, but at low h.atin. rates compared to h.gh.h.atin. rates in.th. O2 atmosph.re, it decreases sign.fican.ly. Th.s suggests th.t a lon.er lign.n.oxidation.process is better th.n.a sh.rter on.. Coats an.

Th. process mech.n.sm an.lysis revealed th.t th. model of first-order an. secon.-order reaction. may adequately describe th. mech.n.sm of h.at degradation.of th. devolatilization.step of olive-solid waste for pyrolysis an. oxidation.processes, respectively.

Measuremen.s were taken.in.a water ph.n.om usin. an.ion.zation.ch.mber to validate th.s model. Th. Percen.age Depth.Dose (PDD) at th. depth.of 0.0, 5.0, 10.0 an. 15.0 cm from th. beam axis for a 10 × 10 cm2 field size was measured an. simulated.

Comparison.of measured an. simulated off-field dose values sh.wed a good agreemen.. Th. average gamma passin. rate of th.
