The pyrolysis liquid can not be mixed with the transportation fuel, and any improvement is required. There is tar trouble, but the know-how to operate the rector is not opened. To get liquid at high yield, rapid heating and cooling are needed, and heat loss and recovery is an important issue. Merit and demerit should be considered.
