أُجريت الدراسة الكيميائية و الفلزية للبنتونيت و الزيوليت إذ تبين .Al2O3-MoO3 – Ag2O المحملين
وجود مونتموريلونيت و الفلز الزيوليتي من نوع "الفلبسيت". فضلاً عن ذلك أُجريت الدراسة الحرارية
التفاضلية لعينات البنتونيت و الزيوليت إذ لوحظت أفعال ماصة و ناشرة للحرارة. و قد درس امتزاز
النتروجين في الدرجة - 196 ° لكل من العينات، و لوحظ تناقص بسيط في المساحة السطحية بحسب
و لانغميور لمزيج البنتونيت و الزيوليت و حفاز الفضة عما كانت عليه في كل من البنتونيت BET
و الزيوليت و مزيج البنتونيت و الزيوليت.
Mineralogical
studies were made to identical the components of the catalyst, montmorillonite
and phylippsite and others were observed. The DTA diagrams indicated
characteristic indothermal and exothermal reaction. The adsorption –
desorption of N2 measurements were carried out at -196°C. A slight decrease of
surface area after having the catalyst been covered with Ag2O.

Most robotic industries depend on using (servo motors) and (stepper
motors) orcontinuous current motors (DC motors) for movement
transition, which increases the cost and complicates the robot’s
controlling process, as well as its driving circuits.
Some kinetic parameters have been determined in this work for thermal and catalytic
cracking of the mixed of polyethylene and polypropylene using batch method. The
cracking reaction was carried out at different temperature 470,490 and 510oC under
The study was carried out to remove of heavy metals (V+5, Ni+2)
under static conditions from aqueous solutions by Syrian Zeolite
mineral extracted from south of Syria. The results revealed that
operational conditions such as initial solution pH and concentration,
adsorbent particle size, the presence of competing cations, are able
to affect the adsorption capacity and efficiency of natural zeolite.
