Abstract
A process for biomass catalytic cracking is disclosed herein. More specifically, the process is in presence of is a mixed metal oxide catalyst represented by the formula (X1O).(X2O)a.(X3YbO4) wherein X1, X2 and X3 are alkaline earth elements selected from the group of Mg, Ca, Be, Ba, and mixture thereof, and Y is a metal selected from the group of Al, Mn, Fe, Co, Ni, Cr, Ga, B, La, P and mixture thereof, wherein the catalyst is formed by calcining at least one compound comprising at least one alkaline earth element and a metal element.
Claims47
A process for catalytic thermolysis of cellulosic biomass, the process comprising heating the cellulosic biomass to a conversion temperature in presence of a catalyst system, wherein the catalyst system comprises a mixed metal oxide represented by the formula (X1O).(X2O)a.(X3YbO4) wherein X1, X2 and X3 are alkaline earth elements selected from the group of Mg, Ca, Be, Ba , and mixture thereof, and Y is a metal selected from the group of Al, Mn, Fe, Co, Ni, Cr, Ga, B, La, P, Ti, Zn and mixture thereof, wherein a is 0 or 1 and b is 0 , 1 or 2.
A process for catalytic hydropyrolysis of cellulosic biomass, the process comprising heating the cellulosic biomass to a conversion temperature in the presence of hydrogen, and in the presence of a catalyst system wherein the catalyst system comprises a mixed metal oxide represented by the formula (X1O).(X2O)a.(X3YbO4) wherein X1, X2 and X3 are alkaline earth elements selected from the group of Mg, Ca, Be, Ba , and mixture thereof, and Y is a metal selected from the group of Al, Mn, Fe, Co, Ni, Cr, Ga, B, La, P, Ti, Zn and mixture thereof, wherein a is 0 or 1 and b is 0, 1 or 2.
